I don't. I don't know. But what I do know is that I like Comet, Diep and TheKing, programs that play nice and pure attacking chess and I really hate more or less the rest of the programs, that try to get in the endgame as fast as possible to promote a pawn. I hate them totally utterly double when they win a high percentage of games with such anti chess. GT is not like that of course, but it's no attack artist either. If you could choose between a more pure and attractive playing style or win more games with an ugly style, what would you choose? Bas.
