colour complex

“Mecking does not understand the significance of weak and strong squares. I have played him three times. In 1969 he lost to me owing to the weakness of his light squares. A year later he presented me with all the dark squares and again suffered defeat. And in the San Antonio tournament of 1972, Grandmaster Mecking again let me have dark-square control, and with it – victory. What distinguishes Mecking is lively piece play, but he has no genuine grasp of the underlying nature of a position; this is what makes me have doubts about his future as a player.” – Tigran PETROSIAN.

  1. You can dominate a weak square, or a few weak squares. When the weak squares are all of the same colour, we say that your strategy is to dominate a colour complex (Bernstein-Mieses). The domination of a colour complex often depends on the balance of Bishops on the board — especially if the defending side has only one bad Bishop.

    space

    We are often told to get at least a stake in the centre in the opening. Without this, you might get pushed off the board (Boleslavsky-Scitov, Hage-Nimzowitsch) With less space, swap pieces if you can. You might find the home of your pawn structure now fits. If you have more space, it might not be…

    tempo

    A tempo is a move, more or less — the turn used to make a move. You can gain or lose (or save) a tempo by your choices, especially in the opening. In the Modern Attack against the Two Knights’ Defence, White paradoxically can gain a tempo by playing, not f2-f4, but f2-f3 (Ng5) then…
