Here's a game I played on the live server against the Lvl 3 computer (HARD), at 2 1 time controls. I was surprised at how large a blunder the computer gave up in the endgame. I mean it really surprised me. Maybe the engine is configured to sometimes go for the second best line? I mean I really don't believe that it thought that was the best line. Anyways here is the game:

I wouldn't say so. I didn't think I really did anything all that great during the game. I guess I just kinda got lucky

I once played a computer.  I won by doing a glitch where I made an illegal move.  It was at ICC or Internet Chess Club.

I think computers are generally weaker than humans at end-games because they see only concrete variations, and are incapable of making plans. You could see whether the position was winning or not with ease while the computer was totally clueless, so it made a few routine moves and lost. Though I do wonder why it didn't resign after your pawns could inevitably Queen...........

c'mon two queens and it took you that long to mate him/her/computer but still nice game
