Double Bishop Endgames

by

Chris Bellers

“Deux fous gagnent toujours, mais trois fous,
non!
“

— Alexander Alekhin, on the advantage of the Two Bishops at
amateur level

This session looks mainly at endings involving BB vs. BN
or NN and no other pieces. They demonstrate that, even where pawns
are evenly placed, the two bishops are often enough to force a
win.

  If you have the two bishops, be prepared for patient
manoevring, and do not assume an automatic win. Game 3.1 is a
particularly long encounter where White gradually builds up a
winning position but slips at the end and should have only
drawn.

1. Opposite coloured bishops While many
opposite coloured bishop endings do end in draws, it is a mistake
to think that all such endings are automatically drawn. It is true
that an extra pawn often does not suffice, and sometimes not even
an extra two or three. However, there are a couple of ideas in
these endings that might be of interest.

  Firstly, there is ‘creeping round the edges’. In the
following position, Black seems to have a successful blockade.


1.1 ?? – ?? (cb), 1995

(wKe4,Be6,Pb7,f5; bKf6,Bb8)

1. Kf3 Bc7 ?

  Black must prevent Kg4, so …Kg5 is necessary

[After 1… Kg5 the game is drawn: 2. Bc8 Bc7 3. Ke4
Kf6 4. Kd5 Bh2 5. Kc6 Ke7 6. Kb6 Bb8]

2. Kg4 Bb8

[2… Kg7 3. Kg5 Bd8+ 4. f6+ Bxf6+ 5. Kf5]

3. Kh5 Bf4 4. Bc8 Bc7

[4… Kg7 5. Kg4 Bc7 6. Kg5 Kf7 7. f6]

 

5. Kh6 Bb8 6. Kh7 Kf7 7. Be6+ Kf6 8. Kg8 Bd6 9.
Bc8

  Again, Black is in zugzwang, and must give way allowing
the f-pawn to advance; once it reaches f7, the bK must go to f8,
and the wK can go ’round to support the other pawn.

9… Ke7 10. Kg7 1-0

 

  The other idea I learned the hard way. In the following
position, Black had lost a [pawn in the opening, and is now forced
to exchange rooks. However, I was not too unhappy about this as I
assumed the position was drawn. What does it look like to you?


1.2 Soesan – Bellars, Paignton, 1976

(wKe3,Bd4,Rb2,Pa5,c4,f3,g3,h2; bKc6,Bg6,Rd7,Pa6,f6,g7,h7)

?! Now the wK penetrates and the bishop is short of squares. The
rest of the game is an object lesson in how difficult it is to
defend with a bishop when the pawns are on the same colour.

[10… Ke6 11. c6 Be8 12. Kc5 also wins]

11. Ke5 Be8 12. Ke6 Kb5 13. Ke7 Bc6 14. Kf7 Kc4
15. Kg7 Kd5 16. Kxh7 Be8 17. Kg7 Ke6 18. h4 Kd5 19. Kf8 Bd7 20. Kf7
Bc6 21. Kxg6 Ke6 22. h5 Be8+ 23. Kg5 Bd7 24. Bc7 Kf7 25. Be5 Kg8
26. Kf6 1-0

 


2. Two bishops with an unbalanced pawn
position

The two bishops are particularly powerful and this alone is often
sufficient to win. The winning process consists of four steps:

place the pieces in the best possible positions
(i.e. where they cramp the opponent’s pieces)

set up an outside passed pawn (or a potential
outside passed pawn) – this means advancing the pawns as far as you
can

if the opponent’s king goes to the threatened
sector, go to the other wing – either to capture pawns with the
bishops or force an entry for the king

If the opponent does not try to stop the pawns
with his king, then advancing the passed pawn will cost him a
piece


2.1 Leonhardt – Bernstein, Barmen,
1905

(wKd3,Be3,g2,Pa2,b3,d4,d5,f4,h3; bKf8,Ng3,Bg7,Pa7,b7,e7,f7,g6,h7)

threatening b4-b5 and if …axb, the a-pawn will not recapture but
run to a8. So, if the pawn gets to a5, it cannot be stopped

7… Bg7 8. Ke2

[8. b4 Bc3 9. b5 axb5 10. axb5 Ke8 11. Ba7 Kd7 and if
now 12. b6 ? 12… Bd4 and the win is not straightforward]

  the second step is over; now we have the fourth idea

2.2 Perlis – Baird, Barmen, 1905

White cannot improve his position any more, and breaks through with
sacrifice to create a passed pawn

[18. bxc5 Nb8 19. Bxb8 Be8 20. Kd5 was
simpler]

18… Nb6 19. Bxb6 Be8 20. Bxc5+ 1-0

 

  Against a doubled pawn the two bishops will generally be
able to force a gain of material, or an outside passed pawn.


2.3 Soultanbieff-Flohr, Folkestone, 1933

(wKg1,Nh1,Bd2,Pb2,b3,d4,e3,f4,h3; bKg7,Bc6,h4,Pa6,b7,e4,e6,f5,h6)

The key here is White’s weak b pawns. The plan is to force b4, play
the K to the Q-side, capture one of the b-pawns and create an
outside passed pawn.

1… Kg6 2. Kg2 Bd5 3. b4 Kf7 4. Ng3 Ke8 5. Ne2

usually clear a path for the king by constricting the enemy
pieces

  Another theme is to exchange a B for N leaving pawns on
the colour of the opposing B.

3. Pawns blocked and/or balanced

The defender drawing chances are greater, but still has a difficult
game. The winning process consists of 5 steps:

1. weaken the opponent’s pawns

2. cramp the opponent’s peces

3. clear a path for the king

4. after the king has penetrated as far as
possible, force the exchange of the blocking piece

5. penetrate with the King and capture
material

in positions where the pawns are all on the same side. Here, even
an extra pawn may not be enough to win

Q

 

  Endings with the pawns all on one side are ALMOST ALWAYS
drawn if the superior side has 3 pawns or less, USUALLY drawn if he
has 4 pawns

 


4. Conclusion

The two bishops are better than two knights or bishop/knight
partnership in most normal positions.

  If the pawns are unbalanced, so that the side with
the bishops can set up an outside passed pawn, it is virtually a
forced win.

  If the pawns are blocked, the slightest weakness in the
pawn structure may be fatal.

  The three ideas in all such endings are:

limit the opponent’s mobility

stalemate the knight

exchange off pieces to transpose into favourable
simpler endings (especially those where the opponent’s pawns are on
the same colour as their bishop

Book review: The Sorcerer’s Apprentice (Bronstein)

[This review first appeared in Westward Ho!]


Book review: The Sorcerer’s Apprentice

by David Bronstein and Tom Furstenburg (1995) Cadogan 1995 ([[sterling]]?.??) 304pp.

This compilation is subtitled

40 Recommendations for the Novice; 40 Combinations with Explanations; 50 Games with Comments; 60 Games with Diagrams; 70 Picturesque Games

  There are also reminiscences and celebrations of Bronstein and his chess by his wife, by Smyslov (written when DB was 50), by the editors of 64 and by Boris Vainstein (at 60), and by the ‘apprentice’ Tom Furstenburg (at 70).

  I’ll skip over the recommendations for the novice, which are hard to quibble with but hard to see the use of. (“38. Only when a position with a mating finish can clearly be seen should you pluck up courage and fearlessly sacrifice a rook or even your queen.”).

  The combinations are given one on a page annotated with a diagram and commentary explaining how it arose, with occasional reflections on the art of combining by DB. Some were familiar, but most not, and all, of course, were a delight.

  The meat in this multilayered sandwich is the set of 50 annotated games, 120 pages of the book. Each game has comments and variations as you might expect, but often also engaging reminiscences about the opponent, or the tournament and the encounter. For example, the eleventh of the fifty was against Tartakower, and bears a splendid tribute to the man in introduction, and a wry anecdote in reflection.

  Among the reminiscences are embedded occasional reflections on chess and computers, and clocks, and Botvinnik, and the 1951 Botvinnik match, and Soviet chess politics. The politics may intrude into the chess in this book as far as the enthusiast is concerned, but it should not be forgotten how far politics intruded into Bronstein’s chess. His father was imprisoned for eight years, and while he was released and attended his son’s match with Botvinnik, he attended without permission to be in Moscow, and David “glanced regularly into the audience in order to reassure himself that his father was still there.”

  Bronstein also gives a couple of examples of his suggestion to record and reflect the time taken over each move, and muses on chess at faster limits for which he has been an advocate for some time.

  The book is a celebration and however partisan some of the commentary I was given to be indulgent.

  The 60 games with diagrams can be followed without too frequent recourse to a board, but I haven’t yet bothered with a lot of the 70 ‘Picturesque’ games given as bare scores. Perhaps a sentence or two of introduction might whetted my appetite – say, ‘A back and forth positional struggle in the last round, decided when White errs with 43…O-O‘. Still, too late for editing now, and I came to them gorged on the earlier feasts, and this apparently dry dessert may tempt me later.

  As an example, I picked this one, which I first saw in Barry Wood’s CHESS in 1976 (along with a 19-move suckering of Smyslov). This is Bronstein the artist and wizard, and even if you don’t know how he does it, it’s easy to admire and enjoy.

Book review: The Modern Chess Self-Tutor (Bronstein)

[This review first appeared in Westward Ho!]


The Modern Chess Self-Tutor

  David Bronstein, tr. Ken Neat

  ISBN 1-85744-136-2 Cadogan, 1995

  I buy chess books for instruction, for reference and for entertainment. This book I judge falls most neatly into the last category.

  Readers will recognise the usual Bronstein style – unconventional, entertaining, chatty; if you enjoyed the 200 Open Games anthology this will also suit you. However, I doubt if the author had a very clear idea about who he was writing this book for, since the topics and examples range from the trite to the magnificent.

  The blurb on the back says that this book “is not a self-tutor in the conventional sense, where the basics of the opening, middlegame and endgame play are drily explained. Instead the author engages in a frank conversation with the reader…”

  It’s all very interesting but can appear loose and self-indulgent. For example, Bronstein takes a page (17) to muse about why, after 1. e4 e5, it is most common to play 2. Nf3, without really answering his own question to my satisfaction. There are even places where Bronstein just wanders off into anecdotes about, say, buying second-hand books with Spassky in South America (p.108).

  Obviously, most of the text is a bit more focussed than that – Bronstein is usually both eloquent and engaging – but although the Chapter headings are enticing (The Strengths And Weaknesses Of The Position, Coordination Of The Pieces, etc.) they are not given a lot of analytic bite. The many examples given are all nice, but occasionally fit the text poorly, in my view.

  For example, on page 51 Bronstein offers: “Everyone knows which piece so frightens the Black King – the White Queen’s Rook, awaiting its hour in the corner.” This is a pleasing aphorism. However, the next example given was:

t+l+tSj+

1…Rxa1! 2. Rxa1 Bxd4 3. Rxd4 Nxb3 4. Rxd6 Qxf2! since 5. Qxb3 allows a choice of either 5…Qxg3/6…Qxd6 or 5…hxg3+ mating.

  It’s a fine achievement from the youthful Bronstein but does it really clarify the point about attacking with Rooks? Recently I showed this game down at the club:

Whiteley – Agnos [A52] 1994

1. d4 Nf6 2. c4 e5 3. dxe5 Ng4 4. Nf3 Bc5 5. e3 Nc6 6. Be2 O-O 7. O-O Ncxe5 8. Nxe5 Nxe5 9. Nc3 Re8 10. b3 a5 11. Bb2 Ra6

  It’s a poorer-quality game but in my view better instructional material.

  In short, there is no sense that the book has been edited with sufficient vigour. You can probably get better instruction for your money from other books, whatever your standard, but if you fancy an interesting chat over some striking combinations with your favourite uncle, this is fine.

Is a doubled c-pawn worth a Bishop?

Is a doubled c-pawn worth a Bishop?

Peter Lane

This is one of the great themes of the Nimzo-Indian and French
Winawer. We will look at it in both contexts: First, the
Nimzo-Indian.

  This method, developed by Huebner, forces the exchange
before White can escape by castling. Black then creates a blockade
on the dark squares.

Impertinent note from typist: when I first came
across this game as an example of weak pawns I was confused – whose
pawns are supposed to be weak? The answer really is White’s,
because his Bishops are hemmed in, and can neither easily defend
the White weaknesses nor attack the Black ones – hence the Black
weakness are more apparent than real.

With this pawn formation White might plan c2-c3, d3-d4-d5, c3-c4,
b2-b4 and c4-c5.

But here d4-d5 and c3-c4 can be met with …b7-b6. So this
formation lacks dynamism. But this dynamic weakness is
conter-balanced by a static strength, as a Pawn on d4 cannot be
forced to advance, being propped up by the c-Pawn. (However, adding
to this we see c4 is weak and hard to defend, and the a-pawn is
isolated. These factors lend Black an endgame advantage.

  We can now make a few comments about Spassky’s play:

  Firstly, White obligingly pushed d4-d5 blocking the game,
whereas any attempt by Black to exchange on d4 would open the
position for the Bishop pair.

  Secondly, the Knight’s development on f3 impedes the push
of the f-Pawn

  Thirdly, the rapid blocking tof the position by fxe5 and
a2-a4 worked against the Bishops.

  Lastly, a continued assault on b6 was needed to constrain
Black’s deployment in some way.

  Let us consider an alternative system of development
based upon the Deferred (Closed) Saemisch Variation, a sometime
recommendation of Keene, and a game with an interesting strategic
point.


Peter Lane – RJJ Gibbons, Exeter Vs.
Kingston, 1995

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 c5

  White loses a move playing a3 to force the chosen
formation.

5. a3 Bxc3+ 6. bxc3 O-O

(too early? – DR’s notes from the Express and
Echo)

7. Bd3 d6 8. Ne2 e5 9. e4 Qc7

  White leaves the f-pawn free to advance; Black’s reply
avoids the pin on g5.

10. O-O Nc6

(Black is playing normal Nimzo-Indian moves, but
White’s opening (with Ne2 rather than Nf3) is too dangerous for
normal methods. …Ne8 and f5 was called for – DR)

11. f4 Bg4?

[11… cxd4 12. cxd4 Nxd4 13. Nxd4 exd4 14. Bb2 Qb6
15. Qc2 and e5]

  Anyone else want to call this a losing move? Note that
Black threatens to exchange on e2, and take at d4. If White takes
dxc5 and fxe5, c4 and e4 become vulnerable to the Knights.
Otherwise White must play d5 – but doesn’t this lead to a blocked
position with White’s Bishop ineffectual as we saw before?

12. d5! Ne7 13. f5!

  Isn’t the first commandment, “Bishop like open
spaces, Knights like closed positions
“? – But White controls
so much of the board, can you find a good square for a Knight? Note
that fxe5, “opening the position”, woud have been a serious error,
allowing …Nd6 and …Ba6.

13…Nd7 (else Bg5) 14. Qe1 Bxe2
15. Bxe2 f6 16. Qh4!

  Now Black sees the idea!

16…Rfd8 17. Rf3 Nf8 18. Rg3 Nc8?

  Dropping a vital Pawn, but:

[18…Nd7 19.Qh6 g6 20.fxg6 hxg6 21.Rh3;

  The ‘interesting strategic point’ is that while the
Knights still always require outpost squares in blocked positions,
the Bishops can work around all but the tightest blockade to find a
diagonal (unless they are required for defence of pawns
attacked by active enemy Knights – DR
).

White went on to win: the ‘bad’ Bishop has a fine diagonal and the
Knight has no good squares.

…1-0

  The ideal structure for Black actually looks quite
different to the Huebner, with f7-f5 in place of d6/e5, and an
assault on e4, i.e. forget about blocking the Bishops, and instead
fight for chances in a more dynamic set-up.

Black wins with a Queen’s-side advance: the Bishop is very bad and
the Knight holds sway on both sides of the board. As in the
Spassky-Fischer game, the White Pawns have become blocked and an
obstruction to his own pieces.

…0-1

White’s Bishop still has some problems, and the struggle for
dominance by the minor pieces is still determined by the pawn
structure, the legacy of the exchange on c3.

Dynamic equality: Black’s knights have achieved favourable outposts
but Black has not enough play on the Queen’s-side for a win, given
the backward c-pawn and strong White Knight. (The weak c-Pawn
prevents a5-b4-a4-b3 and White managed to create play on the
King’s-side.)

1/2-1/2

Summary

I find that in the Winawer, White’s small spatial advantage
allows Black’s Knights room to manoeuvre and blockade the doubled
Pawns. In the Nimzo-Indian it is harder for the Knights to get to
work.

  The Pawns are not good or bad in themselves, only
in how they determine the relative strengths of the opposing
pieces.

  Silman’s ‘Re-assess your chess’
advises:

  When considering an exchange of Bishop for Knight,
ask yourself:

  1. is the position open or closed?
  2. Will there be support points for the Knight(s)? and if
    so:

    1. can the Knight(s) get there?
    2. does it matter if they do? [i.e. are they away from the
      main arena of play?]
    3. what can you do in the meantime with the
      Bishop(s)?
