Crafty completely ignores gxh6?? as an option, and if forced to make the move, realizes the position is drawn at 16 ply (this is within the Fritz GUI, no tablebase access enabled. So what is the code that allows it to avoid gxh6?? immediately, and how does it determine the draw after making the move gxh6? This would be rather easy for Dr. Hyatt to explain, hence the use of the word Crafty in the subject to draw his attention. :)) In any case most programs do see the draw, and without resorting to tablebases.
