I wouldn't call it 'sloppy' at all, just 'different'. A stateless web-based approach to chess by definition has difficulties with a game. I think that Hsu originally wrote this kludged-up thing to play against humans. As I said, he estimated maybe 2200 or so if the opponent is not taking a long time to move. No thinking on the opponent's time. No repetitions. No hashing carried over from move to move. < 1 second of computation time per move. etc...
