Here is a very interesting crazyhouse position, after 1. e4 (0:00.000) e5 (0:00.000) 2. Nf3 (0:01.320) Nc6 (0:00.720) 3. Bc4 (0:00.380) Be7 (0:00.820) 4. O-O (0:01.870) Nf6 (0:00.710) 5. d4 (0:01.650) exd4 (0:03.299) 6. Nxd4 (0:01.050) Nxe4 (0:03.840) 7. Nxc6 (0:06.870) bxc6 (0:03.250) 8. Bxf7+ (0:08.350) Kxf7 (0:02.970) 9. Qh5+ (0:15.160) Kf8 (0:17.680) 10. N@g6+ (0:07.420) hxg6 (0:04.670) 11. Qxh8+ (0:01.480) Kf7 (0:00.770) 12. R@f4+ (0:08.950) B@f5 (0:06.420) 13. Qxd8 (0:04.280) Bxd8 (0:05.760) 14. Rxe4 (0:00.830) N@h3+ (0:06.310) 15. gxh3 (0:02.360) Q@g2+ (0:27.900) 16. Kxg2 (0:02.090) Bxe4+ (0:00.600) 17. f3 (0:01.100) N@h4+ (0:02.630) 18. Kf2 (0:01.040) R@g2+ (0:20.700) 19. Ke3 (0:03.960) Nf5+ (0:07.420) 20. Kxe4 (0:02.140) d5+ (0:09.120) 21. Kd3 (0:01.700) we get to this position [D]r1bb4/p1p2kp1/2p3p1/3p1n2/8/3K1P1P/PPP3rP/RNB2R2 b Black holding: [PP] White holding: [PPNNBQQ] which appears to be a forced win for black!!!! after 21. Kd3 (0:01.700) P@c4+ (0:00.000) 22. Kc3 (0:00.000) Bf6+ (0:00.000) 23. Kb4 (0:00.000) a5+ (0:00.000) 24. Kc5 (0:00.000) we get [D]r1b5/2p2kp1/2p2bp1/p1Kp1n2/2p5/5P1P/PPP3rP/RNB2R2 b Black holding: [P] White holding: [PPNNBQQ] Now it appears that there are two mating moves!!! be7 and bd7!!! When I put this into sunsetter, sunsetter preferes bd7, however if i give it be7, it finds the mate within seconds!! Strange. Sunsetter was unable to find the mate after i gave it bd7 after an overnight analyze. The mate was found by Dragonslayr on FICS and sunsetter only finds it when i play the next moves sunsetter actually advises! Very strange. The beauty of bd7 is that it is a non-check position, and white has lots of checks to give with all that material in hand. (lots of horizon to loook over) regards, lieven
