I played it out with Shredder, and about 40 moves after I made Bg4! it realized, it was a draw. Same with both Tiger's. However, after 2 minutes Crafty, Nimzo, Deep Junior 6.0, and Deep Fritz could not find Bg4. So perhaps Shredder and the Tigers are better "guessers" but they still have no idea what the hell is going on. :) Slate
