With opposite coloured bishops the attacking side has in effect an extra piece in the shape of his bishop.

Along with my retirement from chess analytical work seems to have gone too.

It must be clearly understood that Soviet players do not seek simple systems in the opening, but try to formulate opening systems in which everything is complicated, distinctive, or new.

Every great master will find it useful to have his own theory on the openings, which only he himself knows, a theory which is closely linked with plans for the middle game.

I only think well when my mind is calm.

If you are weak in the endgame, you must spend more time analysing studies; in your training games you must aim at transposing to endgames, which will help you to acquire the requisite experience.

You have to accustom yourself to practical study at home, you have to devote time to studies, to the history of chess, the development of chess theory, of chess culture.
