The placing of the centre pawns determines the "topography" of a game of chess.

The rise of the Soviet school to the summit of world chess is a logical result of socialist cultural development.

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.

Time trouble is blunder time.

Once there is the slightest suggestion of combinational possibilities on the board, look for unusual moves. Apart from making your play creative and interesting it will help you to get better results.
