Others, e.g. Hiarcs 8 or >Gandalf 4.32h (UCI)don't find Nf3+ in acceptable time. I suspect that Nf3+ is not the only winning move. Here is some analysis by movei on p850. It cannot see positive evaluation for black in a reasonable time and needs depth 13. Movei fails high later on Nf3+ but the reason is probably more extensions when Nf3 is a check. depth=13 +0.50 f8f6 g1h1 f6h6 h2h3 g5f5 b3d4 h6h3 h1g1 f5g6 g2g3 c8d7 g1g2 g6h6 a1e1 Nodes: 207226747 NPS: 162217 Time: 00:21:17.46 depth=13 +0.50 f8f6 g1h1 f6h6 h2h3 g5f5 b3d4 h6h3 h1g1 f5g6 g2g3 c8d7 g1g2 g6h6 a1e1 Nodes: 210928916 NPS: 162599 Time: 00:21:37.23 depth=14 +1.35 f8f6 g1h1 e5f3 g2f3 e4f3 f1g1 g5h5 g1g7 g8g7 e2f1 f6h6 f1g1 h6g6 g1d1 g6g2 d1d4 g7g8 Nodes: 445445811 NPS: 163343 Time: 00:45:27.05 depth=14 +1.36 e5f3 Nodes: 491452148 NPS: 164629 Time: 00:49:45.20 Uri
