Nowadays grandmasters no longer study their opponent's games so much, but they study his character, his behaviour and his temperament in the most thorough fashion.

When you play against an experienced opponent who exploits all the defensive resources at his command you sometimes have to walk time and again, along the narrow path of 'the only move'.

In chess, as in life, opportunity strikes but once.

In the middlegame one should not hesitate to advance a central passed pawn.

Two passed pawns advancing on the enemy pieces have brought me more than a dozen points in tournaments.

What the devil possessed me to reply 1. ... e5?? I compltely forgot that Spassky, like Spielmann in the past, very much likes to play the King's Gambit.

A strong player requires only a few minutes of thought to get to the heart of the conflict. You see a solution immediately, and half an hour later merely convince yourself that your intuition has not deceived you.
