I don’t think I’ve felt as sorry for a player for a long time as I have for Kamsky in this game. He certainly doesn’t need my pity, but nevertheless, I’m gutted for him. He played excellently until he missed a couple of subtle moves. He was a hairs breadth from winning the full point, but alas, chess hurts bad sometimes.

Credit though to Cheparinov who had the vision to make life difficult for Kamsky. A phenomenally complicated game. 31 Nh5! Was so energetic, creating all sorts of threatening ideas. He made the position difficult enough so Kamsky couldn’t defend accurately in a complex position.

Hi <Boomie> Absolutely never would I copy words or analysis without giving a name of the writer,

I like analysing games that are interesting and exciting. I spent about 2 hours on the above game, analysing it with my computer. It takes time to check things through and sometimes I get it wrong (always an eagle eyed kibitzer on this website ready to correct you) but I like to try to understand the game as a whole and try to talk about the game instead of just adding reams of analysis. The game here was so complicated that I added more analysis than I usually do.

It's nothing unique to me. Anybody with a computer and a little time can do the same thing.
