I know nothing about chess. I just thought it was an interesting quote about making the next to last mistake instead of just making the last mistake.
"I became insane, with long intervals of horrible sanity." - Edgar Allan Poe
It's not bad. Tartakower was quite a character, though. A couple of other famous chess quotes from him are: "It's not enough to be a good player, you also have to play well" and "Moral victories don't count".
