Take a positional position, where a GM has exact knowledge that it is WON in the long run IF NOT the program makes such and such. And now the clue: it could well be that this is a position where your programs would ALL say I'm better or almost won. I see that you still haven't understood the weak sides of computer chess compared to human chess. Your long range chess sucks badly. Not that I would be happy with it. (But it is clear that the best GM are able to ALWAYS find a new trick to surprise the machine. It's ridiculous to assume that Kramnik suffered badly after ChessBase tweaked the allegedly "horrible" possibility to exchange Queens. Kramnik had hundreds of other weaknesses to exploit. But as I read there will be a re-match, and a re-rematch, so?) Rolf Tueschen
