Here's a good Mate in 9, which I've tried on a selection of engines: 2n2r1k/1rqp2p1/2pR1p1p/1bP1p3/pP5R/P3P3/BB3PPP/3Q2K1 w - - The line goes: 31. Rxh6+ gxh6 32. Qh5 Kg7 33. Qg4+ Kh7 34. Rxf6 Bd3 (or 34. Bb1+) 35. Rxf8 Bg6 36. Bg8+ Kg7 37. Rf7+ Kxg8 38. Qxg6+ Kh8 39. Rh7++ Almost all find 31. Rh6+ more or less immediately, although Hiarcs 7 would probably play 31. Bxe5 (also winning) at blitz. Times for Mate in 9 (200MHz): Junior 5 00:20 LGG 2,0 00:27 CSTal II 00:27 (giving a score of +34.60, not sure what this means) CM6000 00:30 (approx) Hiarcs 7 (180 MHz) 01:10 "White can mate in 13", it says, and remains content. Genius 6 01:30 Crafty 16.6 03:00 Fritz 5.32 11:14 Interesting... Der Bringer ?>30:00 Finds 31. Rxh6+ immediately -- I just love this GUI! Francis PS how do you put tabs into these messages?
