The problem with this is that you don't know, you have to guess. This is not your problem, the problem is that the machine is unavailable and does not compete. As someone who has some interest in saying true things and in not saying false things, I find it very difficult to say anything about DB, or for that matter DT. Absolutely no offense intended, but listening to anyone try to figure out DB is like reading medieval scientific writings. Good conclusions are hampered by lack of evidence and the necessity to avoid contradiction with religious dogma and previous scientific work that is deemed to be undeniably true. The fact is that unless the machine is produced and examined, we cannot conclude anything about it. IBM broke the machine down because they had achieved their goal -- the general population thought that they -- IBM -- had solved chess for all intents and purposes. I oppose this as completely as I can, for two reasons: 1) It did immense damage to the field of computer chess. The general population thinks that chess is solved. 2) The entire thing is not how science is supposed to work. Science does not take a result that may very well be due to chance, and refuse to attempt to repeat it. I absolutely refuse to allow anyone to make an unchallenged assertion that DB was strong at all. The fact is, we do not know if it was strong or not. DB was a PR project. It was not a scientific project. The stated goal of the DB project was to produce as many "impressions" as a Super Bowl commercial, for less money. Absolutely true -- no joke. I give IBM's result as much credence as I give to that UFO cult's assertions that they have produced a human clone, and I think that it is sick that the computer chess community stands for this. >After watching the game today, I get the impression that DJ is broken.

Does anybody know if >the DJ team has been fiddling with the program in preparation for the match? I don't believe that they are allowed to fiddle with it. It is possible that it is broken, but it is also possible that: 1) It has been tuned to play very actively, and the machine decided to pitch an exchange, in a difficult position, for some random reason involving perceived compensation. My own program certainly does this from time to time, even when the position is not necessarily difficult. 2) The strong hardware combined with DJ's well-known great strength created a situation wherein DJ knew it was toasted, and it thrashed out a move when it saw that its original choice was going down the drain. Either of these is very possible. bruce
