The horrible move by Rybka:

Ehlvest - Rybka, Rybka-Ehlvest match 2, 2007, 47...Kb2? (Instantly a draw move)


Analysis by Rybka 1.2f 32-bit:

47.Tb8 Txa7 48.Kxh5 Ta5+ 49.Kg6 Ta4 50.Kf5 Ta1 51.g4 Tf1+ 52.Ke4 Tg1 53.Kf5 Kc2
  =  (0.00)   Tiefe: 15   00:00:30  521kN, tb=4596
47.Tb8 Txa7 48.Kxh5 Ta5+ 49.Kg6 Ta4 50.Kf5 Ta1 51.g4 Tf1+ 52.Ke4 Tg1 53.Kf5 Kc2
  =  (0.00)   Tiefe: 16   00:00:33  592kN, tb=4973

After 46...Kb2?? White can make a easy draw with Rb8!, but Ehlvest blundered (german: Mehrmals!). Lucky win for Rybka.
