But it doesn't see >anything remotely resembling a draw even after 14 minutes. > Here a quote of the analysis: "Selbst wenn Sie Computerschach vielleicht nicht mögen, dafür aber interessante Endspiele, dann schauen Sie sich die folgenden spannenden Varianten an: 60.. h4! 61. Sxg7 h3 62. Sg5 h2 63. Sg3 Kc7 64. Ke5 Kb7. Nun sieht es so aus, als könne Schwarz den Remishafen erreichen, z.B. : A.) 64...Kb7 65. f6 Sd7+ 66. Ke6 Sxf6 67. Kxf6 Kxa7 68. Ke5 Kb6 69. Kd4 Kb5 70. Kx3 c5 remis. B.) 64...Kb7 65. Ke6 Sd5! 66. b5 Sf4+ 67. Ke5 Sh5 68. bxc6+ Kxa7 69. Sh1 Kb6 70. Kd6 Sg7 71. f6 Se8+ 72. Ke7 Sxf6 remis. C.) 64...Kb7 65. b5 (gegen die Verteidigung ...Sb6-d5 gerichtet) 65. ..Kxa7 66. Kd6 Sd5 67. bxc6 Se3 68. c7 Sxf5+ 69. Sxf5 h1D 70. c8D und Weiß hat kaum reelle Siegchancen. Offenbar ließ YACE das Remis aus. In der Partie geschah 60...Kxe8?." SCHACH MAGAZIN 64 5/2003 I hope the analysis is understandable even in German, S=German for knight.
