you know once you subtract all the assinine positions and get right down to
positions that can be safely reached vs strong opposition the actual number of
good positions is a number that alot of pc's could actually handle.i think
people try to make chess seem like this great unsolvable game when in reality if
all the junk were thrown out ,all the good positions prob fit on a 40 gig hard
