It seems that >some engines have a problem to find a mate, not to speak of a mate in 8! On my Pentium III-733 Goliath Light 1.5 (Chessbase engine) finds Mate in 8 in 20 seconds. I suspect that on faster hardware it would find the solution faster than Chessmaster (8 seconds on a Pentium IV-2.4, see John Merlino's post). Could someone with a fast PC try it, please?
