Once in a Moscow chess club I saw how two first-category players knocked pieces off the board as they were exchanged, so that the pieces fell onto the floor. It was as if they were playing skittles and not chess!

Alexander KotovIf 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.
