You must not let your opponent know how you feel.

Anyone who wishes to learn how to play chess well must make himself or herself thoroughly conversant with the play in positions where the players have castled on opposite sides.

Once we have chosen the right formation in the centre we have created opportunities for our pieces and laid the foundation of subsequent victory.

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.

Just as the pianist practices the most complicated pieces to improve the technique of his fingers, so too a grandmaster must keep his vision in trim by daily analysis of positions with sharp possibilities, and this applies whether he prefers such positions in his play or not.

It has always been recognized that chess is an art, and its best practitioners have been described as artists.

Once upon a time supporters of the Steinitz-Tarrasch school had a very high opinion of a queen-side pawn majority. Modern strategy on the other hand categorically denies that such a majority is an independent factor of any importance.
