Thanks for the message about not >taking it all personally. I am understanding your methodology and can now see >your viewpoint. Thanks......Dave Beauregard As I have said before, developing a program to beat human GM players, and developing a program to beat other computer programs, is two distinct things. If you watch on ICC, you will see what I mean. We have a new player there named "guitige" that seems quite good. He played 41 games vs scrappy, and lost all 41. He then went to play another highly-hyped program and got a win, loss, draw and win. He then went back to scrappy and lost 16 more in a row. He then left me a note "very difficult to reach anti-computer positions against your program..." That is what I have been working on for a _long_ time. To (a) avoid blocked positions by understanding them and (b) being able to play endgames vs GMs without fear. You won't find them trying to trade into simple endings in blitz games. It is not so easy to trick it nowadays. against human players, I can afford to make a few necessary positional concessions in order to avoid blocked positions and the draws that follow them around. But against computers, this can be suicide. You really can't afford to give up _anything_ (of course the opponent won't be trying to block the position, but crafty would be doing everything possible to avoid the _possibility_...) That's why I say they are "different" goals. And taking on the "GM problem" is (to me) the interesting one.
