Tartakoverisms

Dr. Savielly G. Tartakover (1887-1956) was famous for his witty sayings, which were called Tartakoverisms. Here are some:

Sacrifices only prove that someone has blundered.
It is always better to sacrifice your opponent's men.
The mistakes are all there waiting to be made.
Moral victories do not count.
A threat is more powerful than its execution.
An isolated pawn spreads gloom all over the chessboard.
Only a strong player knows how weakly he plays.
The player who wins is the one who makes the mistake before the last.
Tactics is what you do when there is something to do; strategy is what you do when there is nothing to do.
The game has three phases: the first when one hopes one has an advantage; the second when one believes one has an advantage; and the third when one knows one is going to lose.
Castling is the first step towards an ordered life.
The great master places a Knight on e5; checkmate follows by itself.
A passed a-pawn looks more dangerous on the second rank than on the seventh.
