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.

I soon realized that it is not enough for a master simply to analyse variations scrupulously just like an accountant. He must learn to work out which particular moves he should consider and then examine just as many variations as necessary - no more and no less.

Experience and the constant analysis of the most varied positions builds up a store of knowledge in a player's mind enabling him often at a glance to assess this or that position.

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.

Drawing general conclusions about your main weaknesses can provide a great stimulus to further growth.
