Supposedly they had GM Benjamin (?) playing DB every day for months, correcting its mistakes. How is this possible without the chips, which supposedly arrived at the very last minute? Either they wasted months of a GM's time just screwing around, or they were tuning a software version of the evaluation function. With this amount of work and expertise going into the project, DB should have been tuned like a mofo. But then we hear about how the mobility weight was all screwed up for one game... how did a mistake like this happen?? If they'd been tuning the mobility weight to exactly the right value for months and months, you'd think they could get it right during the big game. -Tom
