Luck will only take you so far before >it fails... looked at the first 4 rounds. I think Crafty was pretty lucky, as it showed at least two evaluation "problems" that need attention. In the Fritz game it allowed the bishop to get trapped rather than losing one of those passed, connected queen-side pawns. Fortunately it knew that KRN vs KR is almost always drawn, and with the databases it knew *exactly* when this was true. In round 3 (I think) it was also somewhat lucky, as it gave up a pawn to prevent the opponent from castling. This might be ok, but it had to trade queens to close the deal, and simply ended up a pawn down in an endgame. It managed to outplay the opponent, but this could have easily been a draw or a loss. It seemed to understand advanced passed pawns much better than the opponent however and sort of swindled a win. I'm going to look at this and hope it doesn't happen again, since there is no way to get code changes to Jason because the tournament hall has *no* outside connection. It hasn't played its best game yet, I predict. I hope it has played its worst already, however. :)
