I do that. Not sure how many advantages it gives though. >I do this for material. But I can't easily do it for other things. IE "How >many pawns are on this file?" I keep track of that too. Not sure if it's quicker or slower, but it works OK, so I don't really bother checking..... :) I don't do 'how many rooks on each file' though. That gets calculated during the eval. Cheers, Colin
