I'm a chess enthusiast who mostly plays Chessmater 9000. According to the program, after 12 rated games, I'm somewhere around 1000, and that's only because one of the computer opponents, "Argyle", keeps beating my butt. Otherwise I think I'd be around 1200 becasue I have a fairly easy go with all the other opponents rated around the 1000 mark.
What I wanted from Sierawan's book was a good synopsis of modern King Pawn (e4) Defenses since that is what Chessmaster usually plays. I usually play white and I always open with e4. Why make it more complex than it has to be, eh? The real fun doesn't start until the middlegame, anyway, so let's just get there. The sooner the better.
