Remember that their king safety included not just pawns around the king, but which pieces are attacking what squares, from long range as well as close range. Which pieces are attacking squares close to the king, etc. That takes a good bit of computing to discover. Hsu mentioned that 'king safety' was _the_ issue in most of the games. As I look at other micro games (ie fritz 6 in the Israeli league game posted today) it is easy to see why a program that understands square control around the enemy king would have an easy time... But it requires hardware to make this efficient enough that it doesn't kill the search completely... I would like that kind of eval, but I wouldn't like the 1-2 ply search I might get as a result. :) > >I think this is a real no-brainer, and the only reason he hasn't done it already >is possibly because the evaluation function isn't all that it's cracked up to >be. > >-Tom It worked against Kasparov. It worked against a lot of other GM players. A primitive version of it worked against all the other computers in the world... So "maybe it isn't all it is cracked up to be." "maybe it is _more_"...
