Chess quotes:
"In chess, as in life, a man is his own most dangerous opponent." - Vassily Smyslov

"Chess is 99% tactics." - Rudolph Teichmann

"Good players develop a tactical instinct, a sense of what is possible or likely and what is not worth calculating." - Samuel Reshevsky

"No matter how much theory progresses, how radically styles change, chess play is inconceivable without tactics." - Samuel Reshevsky

"Tactics involve calculations that can tax the human brain, but when you boil them down, they are actually the simplest part of chess and are almost trivial compared to strategy." - Garry Kasparov

"Tactics flow from a superior position." - Bobby Fischer

"In general I consider that in chess everything rests on tactics. If one thinks of strategy as a block of marble, then tactics are the chisel with which a master operates, in creating works of chess art." - Tigran Petrosian

"...one other thing is the GM's superiority in tactics. For example Christiansen can find tactics in any position. If you're a GM you should be able to overpower the IM tactically. The GM will often blow out the IM in this area. " - Nick de Firman

"If the student forces himself to examine all the moves that smite, however absurd they look at first glance, he is on the way to becoming a master of tactics." - Cecil Purdy
