A Fortress that Wasn't

This game, played at Corus 2007, was annotated by Anand in the March 2007 issue of Europe Echecs. The players have just captured loose Pawns on e5 and f3. Karjakin tried to set up a fortress with 33.Rc5 Qh1 34.Rc4 Qe1 35.Rf4, but Anand chipped away at the fortifications with 35...h5!

Anand gave his last move '?' and noted, 'Clearer was 47...bxc3 48.Rf4+ Kg6 49.Rf2 Qxh4 50.Kc2 Qd4 followed by the advance of the h-Pawn.' He won anyway on the 63rd move after clearing a path for the a-Pawn.
