The white pieces develop decisive activity, since there is no defence to the double capture on e6, followed by the rook’s entry to c7.

At first sight, Black is in trouble, because 27.Rxc8 is a threat and the bishop cannot escape this attack. But Black has a surprising way to activate:
The white queen is lured to e5, where she comes under attack, and the bishop gets the f5-square. In the game, Black did not find this resource, and after 26...Kh8 27.Qe5+ (he also wins with 27.Rc7 Bd6 28.Qf3 Bxc7 29.Rxc7, or 27.Qc2) 27...Bg7 28.Qc7 Qg8 29.Qxc8 Rxc8 30.Rxc8 Bf8 31.Bf1 b5 32.R1c7 e5 33.g3 e4 34.Bh3, resigned, because of the threats 35.Be6.

The game developed in such a way that Black had to give up on castling. It seems that his king needs to go to h7, freeing the path for his rook. However, Vishy Anand noticed that the white king is located a long way from his pieces, and the Rh8, without having moves at all, can become a great strength in conjunction with the h-pawn!
White shuts off the Bc6, but uses two tempi for this, which suffices for Black to include his bishop in the attack as well, with decisive effect.
He also had no chances of saving the game after 27.Bxe4 Qxe4 28.Qxe4 Bxe4 29.h3 Bxc2.
