Quotes of the Day
Botvinnik and Tal are among the best; I also like Spassky, but I think Petrosian is better than all of them. His weakness is too many draws, even against players he could beat easily. Maybe he lacks self-confidence.
Robert Fischer 1960
“Chess is the struggle against the error.”
Johannes Zukertort

Karpov, Kasparov, Korchnoi have absolutely destroyed chess by their immoral, unethical, prearranged games. These guys are really the lowest dogs around, and if people knew the truth about them, they would be held in more contempt than Ben Johnson, the runner, and they’re going to know the truth when I do this book!
Robert Fischer September, 1 1992
Drawing general conclusions about your main weaknesses can provide a great stimulus to further growth.
