I only see it play positional incredible bad, missing all kind of knowledge. It's really anti-computer style. Nowadays programs have a lot less problems with that. I see crafty even at a dual getting only half speed at which it will run at WMCC blowing away tiger in a positional way at the icc regurarly. Some games Tiger sees lands and sails off to hit the land real soon thereby playing well, others it doesn't see the land in the see and sails to unknown destiny and loses pathetic. To win a championship like this the first priority is a program that doesn't lose at all. I'm not impressed by Shredder's insight in the middlegame. Especially putting pieces into pins and other dangerous anti-positional things is something Shredder happily does, only its deep search and the fact that at these 13+ ply depths there are not many tricks left, allow usually such moves in a tactical way. Yet the bottom line is: shredder hardly LOSES a game. Therefore it always has a good chance to win a championship. Same is valid for junior. It just doesn't blow things quickly. It's missing some fundamental knowledge, but no matter whether it makes mistakes, it doesn't blow it soon. It is not bad in endgame either, one of the big reasons it won 1997 title. Shredder is real good in endgame. Tiger is in a few endgames not bad, but in the average endgame it loses a lot in very weird ways at the icc servers. That's basically blitz of course, so no big deal usual, but the slower games show the same problems also. Crafty might get killed real soon in its book against Kure book who had the chance to study automatically generated books real well as he's a lot on the internet. Against certain other programs crafty will also lose bigtime because of book. So i don't see crafty win either, but it will play in a reliable way of course. Very good tested. If you have a big weak point in your engine, you can shake it winning a heavy champ like this. Finally considering tiger and rebel will have nearly the same book, i definitely would be on the last if my choice was limited to those 2, at least rebel knows something about sacraficing pawns...
