This position is not that difficult, though there is no forced mate. I tried three engines on a PII 400. Fritz 5.32 finds the winning line at 13 ply plus 30 or 40 selective. Takes about 8 minutes. Crafty chooses the right move at 14 ply, though it only gives it 12 centipawns initially. Takes about 20 minutes, and I presume it will stay with that and increase its evaluation. LGGold 2.0 takes the cake again, finding the winning move in 65 seconds, and displaying the winning line and a strong eval about 15 seconds later. It seems quite good at searching tactical positions.
