If a chess statistician were to try and satisfy his curiousity over which stage of the game proved decisive in the majority of cases, he would certainly come to the conclusion that it is the middlegame that provides the most decisive stage.

If you can play the first ten or fifteen moves in just as many minutes, you can be in a state of bliss for the rest of the game. If, on the other hand, Bronstein thinks for forty minutes about his first move, then time trouble is inevitable.

It is better to follow out a plan consistently even if it isn't the best one than to play without a plan at all. The worst thing is to wander about aimlessly.

Once in a Moscow chess club I saw how two first-category players knocked pieces off the board as they were exchanged, so that the pieces fell onto the floor. It was as if they were playing skittles and not chess!

In choosing an opening plan players think most of all of harmonious development for the pieces, but sometimes leave the development of the queen out of their considerations. Yet the Queen is the most valuable and important piece and the whole outcome can depend upon how successfully she plays her role.

The proponents of Steinitz' theory - Tarrasch and his supporters - tried to express Steinitz' teaching in the form of laconic rules, and as often happens in such cases, they went too far. The laconic tended to become dogmatic, and chess began to lose its freshness, originality and charm.

You must not let your opponent know how you feel.
