Yes, Shipov likes 50.-Kd4 and gives the following variations:
50...Kd3? Kramnik laesst hier vermutlich den Gewinn aus. [ Laut Shipov fuehrt
50...Kd4! zum Gewinn.
Einige Beispielvarianten: 51.Re2 f3 52.Rd2+ Ke4! ( 52...Ke5 53.b7 Ke4 54.Rxd6
Rxb2+ 55.Kg3 Rxb7 56.Rc6=)
53.Rxd6 Rxb2+ 54.Kg3 c3 55.Rc6 c2 56.b7 f2 57.Kg2 Kd3 58.Rd6+ Ke2 59.Re6+ Kd1
60.Rd6+ Kc1 61.Kxf2 Kb1]
