Not bad for a slow piece of shit written in BASIC. :) 74,000 NPS 1 31998 16 17 e5f4 d4d3 2 -266 17 90 e5f4 b5d3 2 -266 17 141 e5d4 b7b6 3 -88 18 290 e5d4 b7b6 d4e5 4 -130 22 1735 e5d4 b5c6 d4c3 b7b5 5 -123 29 4619 e5d4 b5c6 d4c3 e6e5 h6e3 6 -128 96 34085 e5d4 b5c6 d4c4 e6e5 h6e3 h8g7 7 -126 263 124417 e5d4 b5c6 h6g5 h8g7 d4d3 b7b5 f6e4 7 -126 461 262591 e5d6 b5c6 d6e7 d4d3 e7f8 b7b5 h6g7 h8g7 8 31992 540 400385 e5d6 b5c6 d6e7 d4d3 e7f8 b7b5 h6g7 h8g7 Now for my my other chess program, Deep BASIC, an ultra slow 16 bit chess program written in QB45. Finds it in a little over 4 minutes processing a massive 4,000 nps on my Athlon 650.

E5D6 Now for my dedicated chess computers... * My Scisys 1850 (1986) worked it out in 3 minutes using the mate solving level. * My Scisys Chess Champion 2150L (1988) finds the solution in 35 seconds using the problem solving level.
