Since I just now finished setting up Crafty 17.14 in Chesspartner and Crafty is
a tablebase program I gave the position to Crafty to see what it would do. It
takes Crafty 17.14 on my K7-900 only 1:07 to play Nxg3 with a score of 0.01.
People who don't want or don't like tablebases simply don't understand.....
