Hard to say based on one game. Yes, Rebel made some positional errors that were obvious to human players, such as letting your opponent take control of a file. But to say that the program "doesn't understand" based on that is a bit much. If you make a little change to king safety or some other aspect, a program can play totally differently. So the issue is tuning and balancing. What I'm saying is that we don't know how far "off" Rebel really is in it's play. What looks like a gross misunderstanding could be cured by a trivial adjustment. The point is that having the man-machine games will allow the program to be tuned for human play. >So where does that leave previous opinions about a DB board for the desktop? >We'll have to see what the next months of Rebel-GM games hold, but the market >for a DB chip is starting to look better and better. Certainly Hsu's card will be held to the same standards as Rebel. In fact Hsu has to perform better. And how easily can any playing aspect of Hsu's card be altered if need be? I tend to think that the card will whip butt on the Rohdes, since a slight tuning inaccuracy will be supported by brute depth search. Rebel needs some tuning, but it may have won anyway if it searched to 15 or 16 ply for every move. Hsu's card will do that easily. The combination of tuning and strength was enough to beat Kasparov, so even though it might be improved, I think it's already pretty close. ;) I suppose for marketing sake though Hsu should be rooting for the humans to beat the existing micros.
