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.

If your opponent is short (on time), play just as you played earlier in the game. If you are short keep calm, I repeat, don't get flustered. Keep up the same neat writing of the moves, the same methodical examination of variations, but at a quicker rate.

I can remember a case where Capablanca worked out an impressive combination, but then chose to make a simple move in answer to which his opponent resigned at once!

After a great deal of discussion in Soviet literature about the correct definition of a combination, it was decided that from the point of view of a methodical approach it was best to settle on this definition - A combination is a forced variation with a sacrifice.

My achievements in the field of chess are the result of immense hard work in studying theory.

Here is a definition which correctly reflects the course of thought and action of a grandmaster: - The plan in a game of chess is the sum total of successive strategical operations which are each carried out according to separate ideas arising from the demands of the position.

When you have finished analyzing all the variations and gone along all the branches of the tree of analysis you must first of all write the move down on your score sheet, before you play it.
