The fastest I have seen is KnightDreamer 3.2, less than a second (amd 1.6ghz): 7210 <first : 6 14 12 87899 d3a6 a2a6 e6e1 c1b2 c6c5 a6a1 e1a1 f1a1 7220 <first : c5b4 c3b4 (732.5k) 7330 <first : 7 36 24 173401 d3a6 a2a6 c6c5 f3g4 d7b5 g4e6 e8e6 a6a1 7330 <first : b5f1 g1f1 c5b4 c3b4 (722.5k) 7541 <first : 8 36 45 339150 d3a6 a2a6 c6c5 f3g4 d7b5 g4e6 e8e6 a6a1 7541 <first : b5f1 g1f1 c5b4 c3b4 (752.0k) 8041 <first : 8 47 94 710173 d3f3 ++ (754.7k) 8112 <first : 8 63 102 771046 d3f3 ++ (754.4k) 8342 <first : 8 94 125 958795 d3f3 g2f3 e6g6 g1h1 d7h3 a6d3 f7f5 d3c4 8342 <first : g8f8 c4h4 h3f1 h2h3 f1g2 h1h2 g2f3 8342 <first : (765.8k) 8953 <first : 9 134 186 1469112 d3f3 ++ (788.6k) 9494 <first : 9 182 240 1931757 d3f3 g2f3 e6g6 g1h1 d7h3 a6d3 f7f5 f1d1 9494 <first : b6f2 d3f1 h3f1 d1f1 e8e2 a2a5 g6g5 9494 <first : (803.6k) That's really good, considering Ruffian and Yace both take about 60 seconds.
