(the only winning move). 49…Rg4 (or 49…Kb6) save the draw. 50.Rf5+ Kxb4 51.Rxh5 Rh1 52.Rh8 Rf1+ 53.Ke5 Re1+ 54.Kf4 Rf1+ 55.Kg3 Kc5 56.h5 Rh1 <Ju now returns the favor>  click for larger view57.Kg4? Missing the win. 57.h6! and 57.Kg2 were winning. A possible winning line:
57.h6 Kb6 58.Kg4 Kc7 59.Kf5 Rf1+ 60.Kg6 Rg1+ 61.Kh7 Kd7 62.Rg8 Rf1 63.Kg7 Rg1+ 64.Kh8 Rf1 65.h7 Ke7 66.Kg7 Rg1+ 67.Kh6 Rh1+ 68.Kg6 Rg1+ 69.Kf5 etc |
Oct-02-19 | | Damenlaeuferbauer: When I lied in bed with a cold and watched this game 10 days ago via live transmission on the internet, I was really shocked, that a reigning women world chess champion could not win an elementary, table base-won rook ending with about 25 minutes on the clock (so time pressure was no excuse): 56. Rd8! When you have just a free rook's pawn in a single rook ending, it is very important to cut the black king 4 files off. 56.-,Rh1 57.Kg4,Rg1+ 58.Kf5,Rh1 59.Kg5,Rg1+ 60.Kh6,Rh1 61.h5,Kc6 62.Kg6,Rg1+ 63.Kh7,Kc7 64.Rd2,Rh1 65.h6,Rg1 66.Kh8,Rh1 67.h7,Rg1 68.Rf2,Kd7 69.Rf8! Only move 69.-,Ke6 70.Rg8! Only move 70.-,Ra1 71.Kg7! Only move 71.-,Rg1+ 72.Kf8,Rf1+ 73.Ke8,Ra1 74.Rg6+,Kf5 75.Rf6+,Ke5 76.Rh6,Ra8+ 77.Kf7 +-
I guess that Em. Lasker, J. Capablanca, M. Botvinnik, V. Smyslov, T. Petrosian, R. Fischer, A. Karpov, G. Kasparov, V. Kramnik, M. Carlsen, and J. Polgar would have won this ending easily. |
