Lot's of great games there too! > >Actually I do not believe there was a 1 bc, 0 or 1ad. I think the sequence went: >2bc, 1, 2ad. Nope. It's 2 B.C., 1 B.C., 1 A.D., 2 A.D., etc. Too bad the rules wern't changed to modern standards until about 1400 A.D. or so. Before that the queen could only move one square diagonally, bishops hopped to every other square along a diagonal, pawns could not move two squares on their first move, a stalemate was a win, and also stripping your opponent down to a bare king was a win. Imagine all the great games lost to us dating back to 8000 B.C. and imagine what CheesBase would be doing to recover all those games! I can see it now: Mega Database 2006 -- 17.4 million games dating back to 8500 B.C.!
