The solution is: 49... Rb4 $3 50. cxb4 a4 $1 51. b5+ Kxb5 52. Ba3 c3 53. Rb1 Kc4 54. f4 Kxd4 55. Kf2 Kc4 56. Ke1 d4 57. Ke2 Kd5 58. Kf3 Bb7 59. Re1 Kc4+ 60. Kf2 b2 61. f5 exf5 62. e6 Bc6 0-1 This position is also part of the Bednorz-Schumacher bs2001 test suite. A suite which is much more difficult and interesting than the wac suite. However, chances are low to solve 90+ prozent of the positions with current programs and to come out with different solutions. It's more 'fun' to run your program against wac - your program will look better, whatever you do. But if anybody who hasn't got the positions is interested, I add the suite in epd hoping to end discussion of dump wac.
