"The great master places a Knight at e5; mate follows by itself."
"Some Knights don't leap - they limp."
"A chess game is divided into three stages: the first, when you hope you have the advantage, the second when you believe you have an advantage, and the third... when you know you're going to lose!"
-- Savielly Tartakower
Good positions don't win games, good moves do.

I've wasted a Black.
[ABRAHAMS, after drawing a game with the Black pieces]
You can retreat pieces... but not pawns. So always think twice about pawn moves.
[Michael STEAN, in Simple Chess]
Open files can be used by both players. The chess player, not being an unselfish advocate of equal opportunity, naturally prefers a one-way system.

When asked, "How many moves do you see ahead?", CAPABLANCA replied:
"One move - the best one." (*)
Similarly, when asked, "How is that you pick better moves than you opponents?", ALEKHINE responded:
"I'm very glad you asked me that, because, as it happens, there is a very simple answer. I think up my own moves, and I make my opponent think up his."
(*) According to Horowitz + Reinfield's "How to think ahead in Chess" (published in the 1940's I believe), it is attributed to someone who BEAT Capa. - Peter Ballard
I have also seen it attributed to Tarrasch!
