Anand is again the first to vary. He clearly wants to stop Topalov from getting his improvements in first. [13...a6

Anand gets out of the way of discovered checks. It is possibly too dangerous to go Queenside although that isn't clear. [17...Kc7

18.a5
This seems to be new. Probably both players had prepared this move although Anand did start to think here. [18.Bb6

19.Bb6
White replied immediately.

19...Rf8
Black continues to try and unravel with Rf8 Bf8 and Rf8-f7-d7 but this takes time of course

20.Rac1
f5
Trying to activate rook and bishop before lines open and White can exploit his lead in development.

21.e5
Keeping Black's light squared bishop locked in.

21...Bg5
Quite a quick reply attacking the rook and intending Bf4

22.Be3

22...f4?
Played quickly again and a terrible move that allows the knight into d6 [22...Bxe3

23.Ne4
Using a discovered attack on the rook to plant his knight on the excellent square d6. It isn't really possible to believe Anand missed this intermezzo, but if he did it was a terrible oversight

was possibly even better]

26...Be7
27.Rc1+
[27.Bb4

27...Kd7
Forced. White has a complete bind in this position so Anand heads for a difficult opposite bishop endgame with drawing chances [27...Kd5

Kd7
As always bishops of opposite colours make the position drawish even though White has an extra protected passed pawn. Now Indian GM Harikrishna proposed a possible winning plan involving a king march to h6 and h4-h5 which I thought was rather unpatriotic of him :)

and the bishop is tied to the d6 pawn. This is terribly hard to assess and in practice unless Vishy thought the line played was losing he would not sacrifice a pawn but I am not sure how White wins from here]

54.Kg5
Topalov is just meandering now but he is about to be rewarded.

54...Bc6??
Within moves of the draw Anand blunders fatally. A truly dreadful move. He removes the possibility of protecting the h-pawn with his bishop which is an easy draw. [54...Bd3
putting the bishop on the b1-h7 diagonal and now Kf7-e8-d7 draws for example 55.f4
