General endgame advice

1 key idea, 3 principles, 15 general laws, 12 practical guides and 6 tips for the ending

One key idea: the passed pawn.

  1. Endgames, and some middlegames, are all about creating and advancing a passed pawn. Either the pawn queens, or your opponent gets so tied up in knots trying to stop it that they lose something else.

3 principles (Fine)

  1. Without pawns, you must be at least a Rook ahead in order to force mate (exceptions: R+R wins against two minor pieces; four minor pieces win against a Queen)
  2. If you are two or more Pawns ahead the win should be routine by advancing the Pawns
  3. With only one Pawn advantage, you will win if you can use it to gain more material – it is not usually enough just to advance the Pawn. Often one Pawn advantage is thought to be a theoretical draw, although the practical difficulties may be very great. Winning by the advance of the Pawn may be won because it allows entry with the King, or causes distraction from one vulnerable side, or allows simplification into a known won ending.

15 general laws (Fine again)

  1. Doubled, isolated and blockaded pawns are weak: avoid them!
  2. Passed pawns should be advanced as rapidly as possible.
  3. If you are one or two pawns ahead, exchange pieces but not pawns.
  4. If you are one or two pawns behind, exchange pawns but not pieces.
  5. If you have an advantage, leave pawns on both sides of the board.
  6. If you are just one pawn ahead, in 99 cases out of 100 the game is drawn if there are pawns on only one side of the board.
  7. The easiest endings to win are pure King+Pawn endings.
  8. The easiest endings to draw are those with opposite coloured bishops.
  9. The King is a strong piece: use it!
  10. Do not place pawns on the colour of your bishop.
  11. Bishops are better than knights in all except blocked pawn positions
  12. Two bishops vs. B&N or N&N are usually a real advantage.
  13. Passed pawns should not be blockaded by the king: the only piece which is not much harmed by watching over an opponent’s pawn is the knight.
  14. A rook on the seventh rank is worth a pawn.
  15. Rooks belong behind passed pawns, of your own or the opponent.

12 practical tips (Mednis)

  1. The king is a fighting piece and should be centralised and used actively.
  2. Material advantage wins endgames: hold on to your material.
  3. Be wary of sacrificing pawns for development: only in Rook+Pawn endings is an active piece worth material.
  4. Try and gain tempi whenever possible, but without giving up material.
  5. The fewer the pieces, the more important the pawns
  6. Keep a flexible, sound pawn formation: avoid doubled, isolated and blockaded pawns.
  7. Passed pawns must be pushed.
  8. The outside passed pawn is an advantage: in King&Pawns endings it is decisive.
  9. Rooks belong behind passed pawns.
  10. In open positions the two bishops are murder: in most other positions they are a real advantage.
  11. In open or semi-open positions a bishop is usually superior to a knight.
  12. The knight is superior to the bishop in blocked positions or when the bishop is hemmed in by pawns on the same colour squares as the bishop.

[cool blue cat says:]

COOL TIP: MEDNIS says ‘good technique’ means:

  1. not allowing counterplay
  2. holding on to material advantage
  3. establishing a clear plan and following it
  4. being careful
  5. never being in a hurry
  6. avoiding complications
    • (and … winning the game!)

Weak pawns

“Doubled, isolated and blockaded pawns are weak: avoid
them!”

  — Fine, Basic Chess Endings

Introduction

“That’s what this match is all about – Pawns,
isolated or hanging. They might just as well play without
pieces.
” — Eddie GUFELD, considering yet another IQP position
in the 1974 Karpov-Korchnoi match (Game 16, position after White’s
24th move)

The English GM David Norwood once said that he made an offer to
analyse and comment on some club players’ games. They expected him
to offer some brilliant analysis, showing them where they had
missed golden opportunities, but his advice was more simple:
“remember Pawns can’t move backwards“. Now, that is one of
the first things any chess player learns, so they were very
disappointed – why was he telling them what they already knew?
Well, they may have known, but they were playing as if they didn’t
know. They were advancing pawns too far, too fast, too often. They
were moving pawns forward which got surrounded and caught, they
moved pawns forward which created holes near their king, they moved
pawns forward which became the focus of a sacrifice. And once they
had moved them forward, they couldn’t move them back. So be careful
with your Pawns!

  The two principal problems with poor Pawn formations
are:

  (1) opportunities provided to the opponents pieces (e.g.
occupation of ‘holes’)

  (2) weaknesses of the Pawns themselves.

  Let us start with a notable example:

Weak pawns: the ultimate collection: Deep Blue –
Kasparov, 1996

 

-+t+-+j+
+x+-+x+x
-Xs+-D-+
+n+x+x+-
-+-+-+-+
P-+-Q-+p
-P-+-Pp+
+-R-+-K-
Just horrible: every one of the six Black Pawns is isolated, or
isolated and doubled! The b-Pawns are also blockaded. Kasparov
staked everything on a King’s-side hack but after 25.
b3!
Deep Blue just grabbed the material and steered clear
of the tactics.

  There is a lot of meat in this game, which I append if
you want to go over it, but it should tell you one thing if nothing
else: weak Pawns can lose you the game.

  Could Kasparov have defended everything instead of trying
to hack? Well, no. It’s a bit like Franklin’s “For the want of
a nail
…”: for the want of a friendly neighbour, a d-Pawn is
weak; to look after the d-Pawn, the Knight is assigned guard duty;
for the want of the Knight, the initiative is lost; for the want of
active play, ground is lost on both sides of the board; for the
want of pieces free from defence, more weakness are conceded…
Once you have more than one weakness, the problem snowballs, and
your Pawns fall like ripe fruit into the arms of your opponent.

  Playing against Pawn weaknesses needs some persistence
but also some flexibility: this transformation of
advantages
is seen in several games below.

  The hanging Pawns have vanished. Has White equalised? By
no means. Black has a superior Bishop, a Queen’s-side Pawn
majority, and one of those odd minority Pawn formations on the
King’s-side which make it difficult for White to make use of his
majority. There is still a lot of play in the position, and Black
won.

…0-1 (42)

  As well as transformation of positional advantages, you
can see changes in the Pawn structure – which may be sought by both
sides. One well-known sequence may transform an isolated Pawn
structure to one with hanging Pawns:

A bit of theory

  There is one general problem with Pawn moves: the
creation of holes, which your opponent’s pieces can occupy.
Tarrasch used to say, “Every Pawn move loosens the
position
“. So the first and simplest form of weakness in a
Pawn formation is the hole.

  There are four principal varieties of weak Pawn:

backward Pawn

doubled Pawns

isolated Pawn

hanging Pawns

  And there is one further idea which you should know
about:

Pawn islands.

  Fine’s comment on the title page is in his endgame book,
which may give you a clue that the weakness of weak Pawns is most
important in the endgame: this is true. It may also give you a clue
that in the middlegame there may be some compensations for having
weak Pawns: this is also true, and is the basis for Tarrasch’s
famous dismissal of the supposed weakness of the isolated Queen’s
Pawn:

“Before the endgame, the Gods have placed the
middle-game.
“

The most miserable Pawn is the backward Pawn. There are very few
compensations for having a backward Pawn. On the other hand, I have
enjoyed demonstrating the positive side of hanging Pawns more than
once; these are probably the least miserable of the lot. Almost any
variety of weak Pawn is more miserable if it is blockaded or
otherwise cannot move out of the way of an attack: this is the
meaning of Fine’s last warning about blockaded
Pawns
. I’ll consider each type of Pawn weakness and
discuss their advantages and if appropriate their compensations.

 


Backward Pawn.

-+-+-+-+
+x+-+xXx
x+-X-+-+
+-+-X-+-
-+-+p+-+
+p+-+-+-
p+p+-PpP
+-+-+-+-
Black has a backward Pawn at d6.

  White has a potentially backward Pawn at c3.

Disadvantages of Backward
Pawns:

The Pawn on d6 is exposed to attack along the d-file but can
neither be supported by a friendly Pawn nor easily be moved out of
the way. The square in front of it (d5) is a potential outpost for
a White Knight.

Possible compensations with
Backward Pawns:

They may support neighbouring Pawns which are strong: above, Black
has a strong central point at e5.


Doubled Pawns

-+-+-+-+
XxXx+xXx
-+-+x+-+
+-+-+-+-
-+pP-+-+
+-P-+-P-
p+-+pPp+
+-+-+-+-
White has doubled Pawns at c3/c4 and g2/g3.

Disadvantages of Doubled
Pawns:

The hindmost Pawn at c3 is effectively backward, but it is the Pawn
on c4 which is most difficult to defend, as no Rook at c1 can
support it.

Possible compensations with
Doubled Pawns:

Doubling of Pawns should yield an open file: here the b-file might
not offer much but the h-file might be worth something. Capturing
towards the centre may give an extra ounce of influence over some
central squares: here the d-Pawn is both supported by a Pawn at c3
while the d5 square is covered by the Pawn at c4.


Isolated Pawn

-+-+-+-+
Xx+-+x+x
-+-+x+-+
+-+-+-+-
-+-P-+-+
+-+-+-+-
pP-+-Pp+
+-+-+-+-
White has an isolated Pawn at d4.

  Black has an isolated Pawn on h7

Disadvantages of Isolated
Pawns:

The isolated Pawn, like a backward Pawn, cannot be defended and
often cannot advance easily. It is therefore weak, and the square
in front of it is a potential outpost for opposing Knights.

Possible compensations with
Isolated Pawns:

The Pawn may support other pieces e.g. Knight on e5, and in the
example the Pawn on d4 gives extra space and mobility to White.
This is not true of Black’s Pawn on h7, which is only weak.


Hanging Pawns

-+-+-+-+
Xx+-+xXx
-+-+x+-+
+-+-+-+-
-+pP-+-+
+-+-+-+-
p+-+-PpP
+-+-+-+-
White has hanging Pawns at c4 and d4.

Disadvantages of Hanging
Pawns:

The Pawns are not quite isolated but have the same sorts of
problems, for, if one advances to be supported by the other, the
hindmost

Possible compensations with
Hanging Pawns:

Hanging Pawns on d4 and c4 confer a space advantage, which can be
nurtured for attack. An advance of one or other Pawn may open lines
for the attack, or result in a Passed Pawn.


Pawn islands

-+-+-+-+
Xx+xX-Xx
-+-+-+-+
+-+-+-+-
-+-+-+-+
+-+-+-+-
pPp+pPp+
+-+-+-+-
White has two Pawn islands to Black’s three.

Disadvantages of extra Pawn
islands:

The Pawns on the edges of Pawn islands are not isolated, but they
are slightly exposed. We might call them “semi-detached”; there is
only one Pawn which can protect them, and only one Pawn which can
protect the square in front of them. This looseness can be
exploited to create more obvious weaknesses.

Possible compensations with
extra Pawn islands:

Gaps between Pawn islands may be useful half-open files. I also
alluded, in the Spielmann-Nimzovitch game above, to a split
minority possibly being better at restraining an opponent’s
majority than an intact majority.

  One might ask:

  why does the side attacking the IQP blockade the square
in front of it?

  and why should the side with the IQP avoid exchanges?

  Simple answers: you blockade the IQP because it may
advance to d5 and blow up your position, and you avoid exchanges if
you have an IQP because the endings are bad for you and you might
make use of the extra space to create an attack.

Black seems to have supported his Pawns nicely, but Fischer’s next
three moves exploit the remaining looseness to create a new
formation in which White has the better minor piece, prospects of
attack, and an enduring initiative.

forced and has the disadvantage of leaving the c-Pawns without

blockades the Pawns.

The Benoni in quotes

John Nunn tells us that the Benoni is often called:

“One big swindle”

C.H.O’D. (Hugh) Alexander once remarked:

“If God played God in the Ben-oni, White would win. But at any other level, Black’s practical chances are excellent.”

The Art of Analysis, Part 2

You aren’t allowed to read on until you have had a go at analysing the games yourself!

Chess and Psychology

Introduction

Many people use the word “psychology” to refer to ‘gamesmanship’, or perhaps to the familiar failings of attention or attitude during play. For example, I have written and collected material elsewhere about getting your mental attitude right: there are examples (good and bad) in the Psychology section of the Canon, there is some good advice on a Poster for Juniors, and in a compilation of Advice for the middlegame. But here I would like to discuss some of the research that has gone on into chess by psychologists – if you like, the science of chess thinking.

 The reason for doing this, apart from my own general interest, is because:

  • chess research has had a big influence on psychology (particularly in skill research: see, for example, Nicolas, Charness, Vicente and Brewer)
  • chess research may have important implications for players
  • many players have misconceptions about what chess research shows: until recently (at least!), this included myself

Chess research seeks to answer: “How do chessplayers think?“. This was actually the title of a commendable series of articles by Simon Webb in CHESS magazine in the late ‘seventies, and if you would like to work through a few examples before reading on, I have collected some material in a separate Web page. I’ll make reference to this page where appropriate below.

Analysis vs. judgement

Many chessplayers have read Alexander Kotov’s book Think like a Grandmaster. It describes how Kotov lifted himself from the also-rans of strong players to become a grandmaster, and what is more, he tells us how he did it: through rigorous training in the analysis of complex positions. His method led him to describe the approach of selecting candidate moves:

“All candidate moves should be identified at once and listed in one’s head. This job cannot be done piecemeal, by first examining one move and then look at another.” — Kotov,A Think like a Grandmaster, tr. Cafferty. [1978] (Batsford)

Kotov also insists that each branch of what may be a complex tree should be examined once and once only: anything else shows lack of confidence and leads to a waste of precious minutes on the clock.

  I know club players who feel guilty because they rarely or never use this technique. There are a number of important points that can be made in reassurance:

  • Kotov was already a strong player before he adopted this approach, and while this may be what one needs to get from FM to IM, it may not be the most important thing for you;
  • not all strong players adopt Kotov’s candidate move approach (would they be still stronger using it? – see position 6/78 – W to move candidate moves?);
    and, most importantly,
  • not all positions are suitable for this approach: it is a way of working through positions of a pronounced tactical nature.

Now, it is possible to conclude that this analytical approach is almost irrelevant to club play. For example, Reti famously once said:

“Those chess lovers who ask me how many moves I usually calculate in advance, when making a combination, are always astonished when I reply, quite truthfully, ‘as a rule not a single one’ “

Moreover, if you read many primers on play: Chernev’s Logical Chess, for example, or his The Most Instructive Games of Chess Ever Played or even Nimzovitch’s My System, they all seem to emphasise positional play and judgement as being the most important aspect of chess.

 There is something quite appealing about concluding that strategical judgement is more important than tactical analysis. It may confirm the supremacy of the world of ideas over the brute and grubby realm of tactics; in a sense, strategy is a more inclusive, higher-level way of talking about positions than tactics, just as the gas laws are a higher-level way of talking about the behaviour of gas molecules.

 But as well as being appealing, it may be correct. Many people have argued that chess research shows that, whatever makes the difference between masters and the rest of us, it’s not the ability to calculate. For example, the British GM David Norwood has published a booklet summarising his views on chess, which includes this statement:

” It is often supposed that, apart from their ‘extraordinary powers of memory’, expert players have phenomenal powers of calculation. The beginner believes that experts can calculate dozens of moves ahead and he will lose to them only because he cannot calculate ahead so far. Yet this is utter nonsense. From my own experience I can say that grandmasters do not do an inordinate amount of calculating. Tests (notably de Groot’s experiments) supports me in this claim. If anything, grandmasters often consider fewer alternatives; they tend not to look at as many possible moves as weaker players do. And so, perversely, chess skill often seems to reflect the ability to avoid calculations. It is, in truth, not clear that chess is a game of calculation. Of course there are times when intense calculation is called for, and often the master is better at dealing with these situations than the amateur. No wonder, he has had more practise than the amateur, but all the same his innate calculating ability need not be any greater. Most of the time it is something quite different that is required in chess, something more akin to ‘understanding’ or ‘insight’.” — David NORWOOD, Chess and Education [1995, Gresham College, London].

Paul Powell’s Chess Page includes a polemic to much the same effect, and there are a number of off-line sources (what are they called again? Oh, yes, “books”) which concur. I’d like to look at de Groot’s research, but first, review the history of chess research that de Groot had to go on before his own studies.

Memory: the touchstone of talent?

I don’t know any other sport or game in which you can arrange a simultaneous display, but it is one of the most impressive demonstrations of chess skill. Masters take on dozens of opponents with little apparent mental effort, and achieve huge winning percentages. There seems no time to calculate, as the moves are made almost at a glance. More amazing is blindfold chess, and yet masters can even give blindfold simultaneous displays.

 What enables masters to do this?

 The most obvious explanation is that they are cleverer than the rest of us. But while there are some links between Chess and IQ, masters are not do not score much more highly than other players – certainly not enough to explain the dramatic differences in performance you can see at a simul. And although chess masters’ memory for chess, as Binet showed, is striking, it seems no better for other spheres.

  In fact, for a long while there seemed not much more to add than that masters are better than other players at chess – full stop. What was needed was some task that was not the game of chess itself, but which showed important differences between masters and the rest of us. One was found in the recall of chess positions.

  The paradigm was established in an experiment by Djakow, Rudik and Petrovsky [1927]. They presented a chess problem to masters and non-players, and found that after a minute’s exposure the masters could recall the position very much better than the non-players, although this is perhaps a difference that one would expect.

  In his book Thought and Choice in Chess, Dutch master and psychologist Adrian de Groot describes how he extended and refined this experiment. He also showed a series of chess positions to a panel composed of four chess players for a few seconds only. Grandmaster Euwe and Master de Groot were very good at this – almost perfect (93%) – whereas other players (an expert and a club player) were much worse (68% and 51%), getting no position entirely right. de Groot talks about a “gulf that separates the master from the non-master“.

  This is a difference that perhaps is more of a surprise. de Groot had another surprise for us too: he showed the following position “A” (from one of his own games) to five Grandmasters and five experts, and recorded and analysed their thoughts:

  He then drew up a table of the number of depth of lines analysed. [ If you would like to compare your thoughts, there is some light commentary here: Comment on (de Groot).] He concluded:

“It is unequivocal that depth of calculation cannot be the prime distinguishing characteristic between the grandmaster and the expert player.“

This hits one with rather a thump. But of course:

“Substantial differences in thinking do exist. The gap between levels of performance of the G- and E-group is enormous: four of the five subjects would almost certainly have won the game; even the fifth would have had a better chance than the E-players who without exception let their opportunity go down the drain.“

de Groot’s research thus led to two things:

  • a widespread belief that GMs do not calculate much better than other strong players
  • a very fruitful series of studies on the recall of chess positions.

The subsequent research on recall (e.g. Chase and Simon’s famous study) is of less immediate interest to me here than research on chessplayer’s thinking as such. There is a lot of recall research, which I summarise briefly:

  • recall tends to be in bite-sized chunks, e.g. fianchetto/castled king [Kg1,Rf1,Bg2,Pf2,Pg3,Ph2], or an inter-related set of pieces in attack and defence
  • errors tend to be of the same “chunked” nature: for example, including typical elements that are normally missing [say, a Bg2], or excluding elements that are not normally present [say, a Pf4]
  • recall by strong players is no better than other players for random positions (Chase and Simon, 1973)

[This seems also to relate to performance: performance in finding mate-in-one by strong players is no better than other players for random positions (CHESS, April 1984, pp. 289-290), although in a best-move test Holding found clear strength differences.]

  There’s a nice real-life example of chunked memory, and playing by analogy, in John Nunn’s game against Korchnoi in the Blindfold round of the 1994 Melody Amber tournament.

 So we seem to have a paradigm for research which is not itself chess, but seems able to tell us something about the way chessplayers perform during games – even suggesting how they think. There was developed the ‘recognition-association‘ model, which suggested that strong players play essentially by analogy: recalling positions and elements of positions, and making judgements about the current position based on this recall. This surely makes a great deal of sense. How often have we seen players flash out the ‘stock’ Bxh7 sacrifice? Is this skill or merely recognition? Gerald Abrahams, in The Chess Mind, argues strongly for the primacy of vision, and says:

“Seeing the idea precedes the logical argument.“

Similarly, Hartston and Wason give an imaginary post mortem conversation which I seem to have heard before:

[Stronger player rejects a move suggested by the weaker player]

  Weaker player: What’s wrong with it?

Stronger player: It’s not good.

Weaker player: Why not?

Stronger player: It’s not the sort of move you play in this sort of position

[end of conversation]

So, this “vision thing” seems more important than memory or calculation. I have two immediate caveats to the direction that chess research took, following de Groot:

  • It should be noted immediately that even if GMs do not calculate much better than other strong players, if you want to be a strong player, then I think you do need to be able to calculate. de Groot presents no data for club-class players compared to “experts”, but I suspect they would be pretty telling. It may not be the thing that is most important for you to improve, and it may be the thing that is most difficult for you to improve, but I have a feeling that tactical alertness and reliability in analysis are important to develop for we club players.
  • Even if we accept that Grandmasters’ judgements and technique are much better, and that many positions do not require analysis, it still may be that GMs do calculate rather better than other strong players when the need arises.

But there are further cautions one needs to make. Anecdotally, I have read:

“… one other thing is the GMs superiority in tactics. For example Christiansen can find tactics in any position. If you’re a GM you should be able to overpower the IM tactically. The GM will often blow out the IM in this area. ” — Nick de FIRMIAN, in How to get Better at Chess Chess Masters On Their Art by GM Larry Evans, IM Jeremy B Silman and Betty Roberts

And in fact, if you look at the the de Groot material again, the GM/Expert measures were completed once for each player, for only one position. It may be that de Groot chose a position with a number of features that made it particularly hard for the experts to grasp. The key move 1. Bxd5 is a little anti-positional and the Black position does not look vulnerable at first blush. It is interesting to speculate what results he might have got with this one: Colle – O’Hanlon, Nice Ol, 1930: 1. d4 d5 2. Nf3 Nf6 3. e3 c5 4. c3 e6 5. Bd3 Bd6 6. Nbd2 Nbd7 7. O-O O-O 8. Re1 Re8 9. e4 dxe4 10. Nxe4 Nxe4 11. Bxe4 cxd4

I guess nearly all players would consider the critical continuation 12. Bxh7+ Kxh7 13. Ng5+, but I suspect experienced masters would run through the tree of variations more thoroughly and deeply than experts and club players.

  Now, Dennis Holding in his 1985 book The Psychology of Chess Skill, collates a number of strands of evidence which suggest that in fact, as we might have all suspected at the outset, strong players do analyse deeper and faster than weaker ones, even in random positions. [But they also are more efficient, homing in on good lines and abandoning duff ones. So it’s not just quantity but also the quality of their analysis which is better.] Norwood’s claims above look more shaky.

  The points made above are not meant to be unkind to de Groot: his work has been so widely cited because it was exciting and important. [I do feel a bit cheated by Norwood, who after all could have found Holding’s work as easily as I could.] But it is in the nature of science to improve on past work. There are lots of other good things in de Groot’s book: for example, when do players abandon a line of thought and look for something better? (Answer seems to be: when the assessment of a position at the end of the variation being considered is out of keeping with the initial evaluation of the position.)

Towards a general model

Teichmann once said that “chess is 99% tactics“, and CJS Purdy added “Chess is the art of analysis“; on the other hand David Norwood and Reti suggest that analysis is relatively unimportant.

  Surely both positions are partly true. (This “one the one hand…, on the other” style makes one yearn for genetic engineers to develop the one-armed academic.) I might offer that memory, judgement and analysis are all important, that we have different abilities and experiences for each aspect, and that different positions make different demands on each skill. Without some pains being taken to discover the balance of skills amongst players of different strengths (style notwithstanding), and the balance of demands of different positions, we are not yet in a position to say what (if anything) is the key to chess mastery.

 In support of this general position, I quote from the abstract of a paper by Dennis Holding:

“The paper reviews the evidence for and against the recognition-association theory and a forward-search (SEEK) theory of chess skill. The recognition-association theory appears to be founded on indirect evidence concerning visual short-term memory, together with supplementary assumptions that may be questioned, and provides no role for verbal processes. There is no direct support for the theory, which omits forward search for reasons that are reexamined. In contrast, the SEEK theory maintains that move choice is based on search and evaluation processes supplemented (or else supplanted) by a knowledge base. These processes are directly evidenced by experimental findings. The objection that search theories cannot account for speed chess is met by a review of the available evidence. It is concluded that chess skill relies on thinking ahead rather than on pattern recognition.” — Holding, PSYCHOLOGICAL RESEARCH, 1992

Now, we needn’t agree with everything Holding says, but it is clear that we may have been hasty in dismissing the importance of analysis (thinking ahead).

  The whole of this issue of Psychological Research is devoted to chess, and Holding has written a whole book on The Psychology of Chess Skill (1985). There is clearly much research of interest going on, much of which suggests that chess is more complicated than the ‘recognition-association’ model. And however resounding the pronouncements made about the importance of chess skills, chess remains more complex, and more interesting, than any pat statement.

  One last point. It may be that de Groot had something right all along, namely, his method. I think part of the attraction of the later recall paradigm is that there is no messiness: subjects are given a definite task and the languageless patterns of results are scored according to a definite scheme. But de Groot saw no virtue in this style of work: in fact his book is in part a long plea in favour of “introspective” methods in psychology, where subjects are encouraged to talk about their thinking, and the whole messy, unreliable collection of their words is analysed. I have a suspicion that rather than seek the key(s) to chess through some neat experimental technique, the closer we come to studying chess itself, the more likely we are to find an answer.

In addition to books and papers cited above, I have found interesting and useful Krogius’ Psychology of chess and Pfleger and Treppner’s Chess: the mechanics of mind. Hartston and Wason have published a readable book on the Psychology of Chess: it has had favourable reviews and covers the psychoanalytic approach rarely referred to elsewhere.

“The most important feature of the chess position
is the activity of the pieces. This is absolutely fundamental in
all phases of the game (opening, middlegame and especially endgame). The primary constraint on a
piece’s activity is the Pawn structure.

itself but in its usefulness for concrete ends.

A.1. Vanished centre

e.g. Scotch 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 then …d5 and

  The placing of the pieces and/or a development advantage
will decide if the game has any real meat.

A.2. The QP centre

e.g. French 1. e4 e6 2. d4 d5 3. exd5 exd5

  The open e-file and outpost at e5 (e4) may become crucial
if pieces are allowed to settle there. The natural break c2-c4 does
little to add tension, unless castling is performed on opposite
sides; the Q-side is then risky with outpost at c5.

A.3. The KP centre

e.g. Philidor or Closed Lopez 1. e4 e5 2. Nf3 d6 3. d4 Nd7 4.

  Assuming King’s-side castling, the break f2-f4 is much

A.4. Symmetrical Four Pawns
Centre: (i) KPs forward

e.g. Closed Giuoco Piano 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. d3
d6

  White can prepare the advance d2-d4 with c2-c3, or go for
f2-f4. Black may try to prevent this e.g. h7-h6 and g7-g5, or go
for broke on the Queen’s-side.

A.5. Symmetrical Four Pawns
Centre: (ii) QPs forward

e.g. Queen’s Pawn Game 1. d4 d5 2. Nf3 Nf6 3. e3

  The advance e2-e4 is more difficult to achieve than d4 in
A.4; the more common plan is c2-c4 and a shift of
the struggle to the Queen’s-side. If for some reason c2-c4 is
impossible or undesirable, then e2-e4 must be sought.

B.3. Partially Fixed Centre
(i) tension form

e.g. Philidor and Closed Lopez 1.e4 e5 2. Nf3 d6 3.d4 Nf6 4.

  White will try to maintain d4 with c2-c3 and use extra

b6 4. Bd3 c5 5. f4 Ba6 6. Nf3 cxd4 7. Nxd4 Bxd3 8. cxd3

  White has a post on d4 for a Knight. The major pieces may
come off on the c-file, when White has a post on d4 for a King;
without exchanges White can play for attack and break with
f4-f5

B.7. Mobile Centre (i) King
Pawn

e.g. Nimzo after exchanges of the d- and c-pawns, or other slow
opening after d3, e4 and …d5xe4

  There will be a struggle for e5 e.g. White will sieze it
with a N and play for attack. This can be resolved by the advance
of either e-pawn, when we have structures considered above.

B.8. Mobile Centre (ii) Queen

e.g. Indian Defence with …e5xd4, e3xd4, or Alekhin Exchange
variation 1. e4 Nf6 2. e5 Nd5 3. c4 Nb6 4. d4 d6 5. exd6 exd6

  White has a space advantage and is very likely to play c4
(else …d5 will come quickly), when Black will be short of space.
Black must put pressure on the White centre.

  There will be a struggle for d5, which can be resolved by
the advance of either d-pawn, when we have structures similar to
those above, although White can go for a bind with c4-c5.


C. Extra Central Pawns

C.1. Absolute Centre

e.g. King’s Gambit Declined 1. e4 e5 2. f4 Bc5 3. Nf3 d6 4. c3
or Nimzo after cxd5,…exd5 and e4, …dxe4 and fxe4

  A substantial asset, but not decisive – the reason being
the pressure that can be put on the pawns by the opponent’s rooks
(they are in fact a type of hanging pawns). If the centre can be
kept intact, and perhaps advance, then the advantage will manifest
itself.

 


-+-+-+-+
Xx+-+-Xx
-+-+x+-+

C.2. Hanging Centre

e.g. French 1. e4 e5 2. d4 d5 3. Nd2 Nf6 4. e5 Nd7 5. Bd3 c5
and later dxc5, and …f6,exf6, …Nxf6

  Another hanging formation, with a key square at e5. If
White can occupy e5 or at least prevent …e6-e5 then Black will be
worse. Usually Black can keep White pestered with enough nuisances
to keep in the fight, but often a single tempo will make the
difference between a successful blockade and a successful
advance.

 


-+-+-+-+
XxX-+xXx
-+-X-+-+

C.3. Classic Centre

e.g. Giuoco Piano 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5.
d4 exd4 6. cxd4

  One of the strongest formations – if White can keep it
intact. In the Giuoco Piano line above Black can disrupt it with
…d5. But if Black retreats with 6…Bb6 the centre will either
form the basis of a crushing attack, or simply roll forward.

 


-+-+-+-+
Xx+-+xXx
-+x+x+-+
+-+-+-+-
-+-Pp+-+
+-+-+-+-
pP-+-PpP
+-+-+-+-

C.4. Neo-Classic Centre
*

e.g. Slav, Queen’s Gambit Accepted, Grunfeld Defence, Queen’s
Indian 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 dxc5 5. a4 Na6 6. e4 or
1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. Qb3 dxc4 6. Qxc4

  Again strong: Black’s best hopes are to hit at it with
…e5 (risking d5) or …c5. Sometimes in the Grunfeld …f5 may
play a part.

 


-+-+-+-+
Xx+-+xXx
-+-+x+-+
+-+-+-+-
-+-Pp+-+
+-+-+-+-

C.5. Neo-Classic Centre: with
open file

e.g. Grunfeld 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4
Nxc3 6. bxc3 c5 7. Bc4 Bg7 8. Ne2 cxd4 9. cxd4

  Tactically this may still be dodgy for Black, but
strategically is prefereable to C4, as the cramp
is less, the opportunities to hit at the centre (and directly at
pieces) are better, and the Queen’s-side majority is an endgame
plus.

 


-+-+-+-+
Xx+-+xXx
-+x+-+-+
+-+-X-+-
-+-Pp+-+
+-+-+-+-
pP-+-PpP

C.6. Unbalanced tension
form

e.g. Slav 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. e3 Nbd7 6.
Bd3 Bd6 7. O-O O-O 8. e4 dxc4 9. Bxc4 e5

  A tense formation: White can exchange on e5 (rival
majorities), Black can exchange on d4 (ditto), or White can push d5
(not strategically worrying for Black, but may be troublesome
tactically).

 


-+-+-+-+
XxX-+xXx
-+x+-+-+

C.7. Latent Central Majority
(i) QP in reserve

e.g. Delayed Exchange Ruy Lopez 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6
4. Ba4 Nf6 5. O-O Be7 6. Bxc6 dxc6 7. d3

  Often in the RL Exchange White plays d4, and after
…exd4 has a free majority on the King’s-side. Here Black would
play …c5 if White hinted at this, so White must either play more
slowly for d4, or try f4, or leave things in the centre as they are
and creep over to the King’s-side for an attack on the Black
King.

 


-+-+-+-+
Xx+-+xXx
-+x+-+-+
+-+x+-+-
-+-P-+-+

C.8. Latent Central Majority
(ii) KP in reserve

e.g. Queen’s Gambit and Caro-Kann Exchange. 1. d4 d5 2. c4 e6
3. cxd5 exd5 or 1. e4 c6 2. d4 d5 3. exd5 cxd5.

  White has a choice of plans: to prepare the advance e2-e4
(usually by f3), or to play the minority attack.

  The e4 advance is favoured by (a) the d4-pawn not being
vulnerable, and (b) two bishops to fight in the resulting open
position. So in the line 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. a3 Bxc3
5. bxc3 d5 6. cxd5 exd5 all the signals are there for the e4 plan
to be favoured; in the QGD the minority attack is most common.


D. Closed Formations

D.1. Blocked oblique (i) QP

e.g. King’s Indian 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 O-O 5.
Nf3 d6 6. Be2 e5 7. d5, or from Ruy Lopez with d4-d5 (cf.
B3)

  White has only two ways to open a file: the breaks f4 and
c5. The former may leave a weak backward pawn on e4 after …e5xf4
(even if White can reply g3xf4), so the latter is preferred. Black
will naturally counter with …f5. White can also easily achieve
b4, with a strong Queen’s-side initiative, but Black’s attack on
the castled White King is dangerous.

pPp+-PpP

D.2. Blocked oblique (ii) KP
forward *

e.g. French advance 1. e4 e6 2. d4 d5 3. e5 (also
Caro-Kann)

  In practice …c5 and …cxd4, cxd4 is common,
tranferring the position to F3. Without …c5
Black is crushed by the advance f2-f4-f5. So the only important
position is if Black pushes past with …c5-c4, as in the line 1.
e4 e6 2. d4 d5 3. e5 c5 4. c3 Nc6 5. Nf3 Qb6 6. a3 c4. White will
still aim for the attack, but Black can play for infiltration of b3
and to open lines with …b5-b4. Black can castle Queen’s-side, but
this may make …b5 more difficult.

D.3. Stonewall

e.g. most common is the Dutch 1.d4 f5 2. c4 e6 3. Nf3 Nf6 4.
Nc3 d5, but also Semi- Slav and other QP openings.

  Black plays for a King’s-side attack, with an outpost on
e4 and a pawn-break …g5 and …f4; White’s easiest strategical
plan involves assault of c6 with c4-c5 (usually) and b4-b5
(always). White can also try to get at e6 with f3 and e4.

  More generally White must aim at restraint of …e5,
exchange of dark-squared bishops, and controlling key squares with
Ns on f3 and d3.
Usually c4xd5 is met by …c6xd5, but if White is organised for b4
then …e6xd5 may wrong-foot White’s pieces.

D.4. Anti-Stonewall

e.g. Semi-Slav 1. d4 d5 2. c4 c6 3. Nc3 e6 4. e3 f5 5. f4!

  If White has this option Black is advised to avoid the
Stonewall; the King’s-side attack is unlikely to get far and the
assualt on c6 is just as dangerous.

D.5. Pseudo-Stonewall
(Botvinnik)

e.g. English Opening 1. c4 c5 2. Nc3 Nc6 3. g3 g6 4. Bg2 Bg7 5.
e4

  If Black can organise …d5 White’s formation will
shatter; White must adopt a move-order whereby …d5 is impossible
or undesirable. Then the central bind can enable a King’s-side
initiative with f2-f4 and f4-f5. If both players adopt this
formation, the advantage will go to the player who achieves f4
first.

D.6. Wyvill Formation

e.g. Nimzo-Indian 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 b6 5. a3
Bxc3 6. bxc3 d6 7. e4 Nbd7 8. Bd3 O-O 9. O-O e5 10. d5

  Marmaduke Wyvill, the nineteenth century MP, specialised
in this formation; the details are important here.

  Ideal for Black is an outpost on c5, and Queen’s-side
castling. Then the assault on the weak c-pawns can be carried out
in safety, and Black can even think about opening a file with
…f5. But White should not volunteer for d4-d5, and usually Black
can only induce this by playing …c5; if in addition Black has
castled King’s-side White has good chances.

  Sometimes pressure with …Re8 and …Qe7 threatens a
discovery with …e5xd4, and this may be enough to provoke d4-d5;
Euwe once played …Na5, …Ba6 and …Qe6!

D.8 Winawer Formation

e.g. (and almost exclusively) 1. e4 e6 2. d4 d5 3. Nc3 Bb4 4.
e5 c5 5. a3 Bxc3 6. bxc3.

  White has prospects of a King’s-side attack with f4-f5,
but Black’s attack on the c-pawns can be certain of opportunities.
The big structural disadvantage for Black is the lack of the Bf8,
creating possibilities of a dark-square campaign. Black should
castle Queen’s-side, if at all.

pPp+-PpP

E.1. Ruy Lopez
Formation

e.g. Philidor or Ruy Lopez Steinitz Variation with
…e5xd4.

  White’s superior mobility gives a lasting advantage. It
can be milked for a direct attack on the King; White can post the
Bc1 on b2. These days most players don’t fancy this defensive task
as Black and try to maintain the e5 pawn.

E.2. French/Caro formation

d5 3. Nc3 dxe4 4. Nxe4

  With the Bc8 stuck behind the Pe6, Black has a lasting
problem. White can post a Knight on e5 and play sharply to restrict
Black’s pieces and attack the Black King.

  It is natural to seek …c5, but even after an exhange
White has the Queen’s-side majority. In the Caro version the Bc8
usually escapes, so Black’s chances are better here, even if it
takes two moves to play …c5. Very often Queen’s-side castling is
an option for either side.

E.3. Sicilian Formation
*

e.g. 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3

  A very delicate situation strategically; White has a deal
more space, and prospects of a King’s-side attack. But Black has an
extra central pawn, a minority attack and pressure down the c-file,
and myriad tactical opportunities.

  The development of the Bf8 is important; after …e6 and
…Be7 Black has good central control but a slightly weak point on
d6; the centrally sounder …g6/…Bg7 adds so much to Black’s
Queen’s- side play that Black would play it all the time, if it
didn’t also create new opportunities for White’s King’s-side attack
after h4-h5.

  White can achieve a powerful bind, and stop Black’s
counterplay, by playing c2-c4. Black may be able to equalise by
good defensive play and achieve a freeing break with …b5 or
…d5, but it is essentially a defensive task that misses out on
the counter-attacking possibilities of the Sicilian.

5. Bg2 Nb6 and later d4 and …e5xd4; see also
E3.

  Simply, each side must advance their majority.
With Queens on, advancing pawns on the King’s-side cannot be done
casually, but neither can their advance be ignored.

E.5. Rival Majorities (ii)
with no open file between

This formation can be achieved by the centre pawns pushing past
each other once their partners have been exchanged, but more often
it will arise from A2/A3 after an exchange on an
outpost square.

  The plans are clear for each side; the bishop’s pawns
must advance, with equal chances.


F. Half-open
formations

F.1. Half-Open with an open
file (i) symmetrical

e.g. Echange Slav 1. d4 d5 2. c4 c6 3. cxd5 cxd5

  This is plainly similar to other symmetrical formations,
with tactical or dynamic features (lead in development, two
bishops, concentration of force) being more important than the pawn
formation. The structurally important thing here is on which side
the dark-squared bishops are placed.

F.2. Half-Open with an open

e.g. Ruy Lopez, Tchigorin Defence 1. e4 e5 2. Nf2 Nc6 3. Bb5 a6
4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 O-O 8. c3 d6 9. h3 Na5 10.
Bc2 c5 11. dxe5 dxe5

  This is strategically very much richer. Usually there are
too many pieces around for invasion via the d-file to be possible,
but it should not be overlooked. White has an outpost on d5, and
after an exchange on d5, e4xd5 gives a passed pawn and the Bc2 and
Nd2 can look forward to a bright future. White also has a plan of
Nf5 and a King’s-side attack, and may seek to control c4 after
a2-a4.

  Black has counterplay on the Queen’s-side, and if c5-c4
proves possible, Black suddenly has avoided any nasties on c4 and
has a goal on d3. So White’s pursuit of King’s-side goals cannot be
careless.

F.3. Half-Open with an open
file (iii) Blocked Oblique

e.g. King’s Indian, Ruy Lopez or French; cf.
D1/D2

  The discussion in D1/D2 was all about how to open a file,
but here such a file already exists. Four possibilities present
themselves, combining each central pawn being forward with either
bishop file being open. Care and exploitation of the open file
affects markedly the plans described above; both players may switch
to the side with the open file in order to keep an eye on it.

  Exchanges of rooks down the open file reduce the chances
of a successful mating attack, but do not much reduce the
positional pawn advances.

F.4. Half-open with half-open

Nf6 4. e5 Nd7 5. f4 c5 6. Nf3 cxd4 7. Nxd4 Bc5 8. Be3

  Black has chances against the Queen’s-side; c4 is an
outpost that cannot easily be disturbed by b2-b3. White’s chances
come on the King’s-side, and the attack must be swift and sure – f5
and h4 may figure in the attack. White should maintain a Knight at
d4, although Black can exchange or otherwise badger it. If Black
can force White to abandon d4, then the advance …d5-d4 may decide
the game in Black’s favour.

F.5. Half-open with half-open
files (ii) Caro-Kann / QGD Exchange

e.g. 1. d4 d5 2. c4 e6 3. cxd5 exd5 or 1. e4 c6 2. d4 d5 3.
exd5 cxd5

  We see this formation from White’s point of view in the
diagram, where we might expect White to be better developed than
Black. The half-open e-file and outpost on e5 gives prospects of a
King’s-side attack, even if Black had the majority there, as the
advance …e5 will be difficult or impossible. Black must counter
with a minority attack, and can think about spending a moment to
exchange the bad Bc8.

F.6. Passed pawn, protected
but blockaded

e.g. This may arise from D1 after an exchange
on c5.or from C4 after the advance of both the c-
and e-pawns is combined with the advance of the d-pawn

  White has a difficult game: no way of opening a file
recommends itself, and Black can roll down the Queen’s-side. With
the e-pawn replaced by a pawn on c4, Black’s chances would
naturally come with …f5. The best blockader is always a Knight,
who loses no squares to the pawns on c5,d5 or e5, and is handily
placed to support pawn advances on either side.

F.7. Isolated Queen’s Pawn
*

e.g. Queen’s Gambit Accepted 1. d4 d5 2. c4 dxc4 3. Nf3 Nf6
4.e3 c5 5. Bxc4 cxd5 6. exd4 or Caro-Kann Panov Attack, 1. e4 c6 2.
d4 d5 3. exd5 cxd5 4. c4.

  Isolated pawns are weak, but central pawns are strong.
The critical and common case is the isolated Queen’s pawn (IQP)
where the strength and space is greatest. White can avoid exchanges
and has hopes of a King’s side attack based on a N on e5 and a B on
the b1-h7 diagonal; Black can consolidate and pile up on the d4
pawn, seeking exchanges and an advatageous endgame.

F.8. Hanging Pawns *

Often derived from IQP after …Nd5xc3 and bxc3, then c3-c4.
Directly from e.g. Semi-Tarrasch 1. d4 d5 2. c4 e6 3. Nf3 Nf6 4.Nc3
c5 or Queen’s Indian 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. e3

  The pawns are strong and can be turned to attack because
they control so many key squares, but if either pawn moves the
weakness of the other will be sharply etched. Again, the defending
side can seek exchanges and the endgame, but this is nothing like
as straightforward a game as the IQP. There is a defensive idea
based on the advance of the isolated a-pawn, hoping to disrupt the
Black Queen’s-side pawns.

 

You know when you’ve been Benko’d

Steve Homer


In the Benoni Black often struggles to arrange …b5 with moves
like …Na6-c7, …b6, …a6 and …Rb8. Here in the Benko Black
plays it at once, as a gambit.

Key ideas for Black:

For example, in the main line after

1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.bxa6 g6
6.Nc3 Bxa6 7.e4 Bxf1 8.Kxf1 d6 9.Nf3 Bg7 10.g3 0-0 11.Kg2
Nbd7

 

r+-+qB-R
PkP-+-Pp
-Pn+-N-+
+-+p+-+-
-+-+pX-+
+xS-X-+-
xLxXs+-+
+jT-D-+t

  • Control of long dark diagonal, especially the central dark
    squares e.g. …Nfd7-e5

     

  • Pressure against the d5 Pawn

     

  • Queen’s-side attack with e.g. …Qb6, …Rfb8, …Nbd7-b6-c4.
    White’s extra passed(!) Pawn usually remains frozen with terror on
    a3 or a4.

     

  • Central attack with …e6, …d5

We can see all of these ideas below. White must counter on the
King’s-side or in the centre. Oddly for a gambit line, Black
usually won’t mind the exchange of Queens in the Benko, because the
Queen’s-side initiative persists, while White can no longer hope
for mate on the other side.

  However, in none of the games below did White play the
main line, and in only one was the gambit Pawn accepted! This is
not just to avoid theory, as, according to BCO, Black often emerges
with enough pressure to draw in the main lines.
