Yar seems to be claiming that Shredder stated that BLACK has the mate in 58 moves. At least, that's what I'm assuming because it is Black to move and Yar said "mate in 58". However, Chessmaster is saying that WHITE is winning (positive scores always favor White in the CM GUI). I am not at all convinced that Shredder's announcement of mate is accurate. In particular, I would like to see the PV (all 115 plies of it!). jm
