Larry Evans, Chess Grandmaster, 1932-2010

I learned a great deal about chess from Larry Evans.  I still have my copies of his edition of  Modern Chess Openings (as well as Korn's 12th, the last to be printed in English Descriptive Notation) and Fischer's 60 Memorable Games.  My copy of New Ideas in Chess still finds its way into my bag for subway reading.
Here is something from New Ideas in Chess under the heading "A wing attack is best met by a reaction in the center".  It, like all of the examples in New Ideas, is drawn from his own tournament games.  This one is from Kagetsu v. Evans, Hollywood Open, 1954.

after ...P-Q4

Evans writes of this position: "This attacker does not always benefit from open lines.  He should try to close the center before embarking on a wing attack.  This cannot always be done.  The defender must keep his lines of communication open, and this requires a fluid center so that he may divert pieces from the other wing to the defense of the attacked wing".

A Small Game of Chess

I do not usually win against my many chess programs. That being said, I also do not believe that Chess programs "think". The problem with the computer is that, unlike a human, it can access every game ever played. It is like a human having access to every book ever written and every game ever played, and you have only what you can remember and tactics and strategies that you have learned. However, I play almost every day. The best program I have found is GnuChess and the engine associated with it called Phalanx. The following game was played against a weaker, but still passable, program.
