One of the things that first attracted me to chess is that it brings you into contact with intelligent, civilized people - men of the stature of Garry Kasparov, the former world champion, who was my part-time coach.
Economy, prudence, and a simple life are the sure masters of need, and will often accomplish that which, their opposites, with a fortune at hand, will fail to do.
I haven't played a chess match for several decades. At one point I lost most of my chess games. Then I realized many of my competitors were memorizing the best moves and I was unwilling to do this.
