Tartakower once wrote that after planting a Knight in the center you can go to sleep. This is not to be taken literally, of course, but it contains more than a germ of truth.

It often happens that a player is so fond of his advantageous position that he is reluctant to transpose to a winning endgame.

Young players calculate everything, a requirement of their relative inexperience.

The knight is renowned for, among other things, its suitability as a blockader ... Because its strength lies in short-range operations it is not uncomfortable standing in a single spot for long periods, as the Bishop is.

By playing slowly during the early phases of a game I am able to grasp the basic requirements of each position. Then, despite being in time pressure, I have no difficulty in finding the best continuation. Incidentally, it is an odd fact that more often than not it is my opponent who gets the jitters when I am compelled to make these hurried moves.

We often hear the terms 'positional' and 'tactical' used as opposites. But this is as wrong as to consider a painting's composition unrelated to its subject. Just as there is no such thing as 'artistic' art, so there is no such thing as 'positional' chess.

My style is somewhere between that of Tal and Petrosian
