Tactical knowledge is based mainly on captures, etc. and that is why most chess programs exceed when they search greater depths, but positional knowledge is one of the main things that most programmers are seeking. Both Belle and TECH relied upon tactics, mainly going to greater depths to find captures. It was not enough. Control of center and of the board, ie. mobility is where most of the better programs are finding their greatest strength. Bill
