Should Carlsen triumph, he will, outside India, be widely expected to take the crown from Anand. Yet the title-holder is a vastly more seasoned match-player: it would be a fearsomely tough contest. The champion, more than 20 years older, has a lifetime plus score against Carlsen; but last year the Norwegian gained only his second victory at classical time-limits against Anand. I suspect this game will be giving the world champion nightmares, as Carlsen outplayed him with astonishing simplicity of means: 

1.e4 c5 2.Nf3 d6 3.Bb5+ (Carlsen plays a move thought to be innocuous: but he wants to avoid Anand's famed opening preparation in the main lines) Bd7 4.Bxd7+ Qxd7 5.c4 Nf6 6.Nc3 g6 7.d4 cxd4 8.Nxd4 Bg7 9.f3 Qc7 10.b3 Qa5 11.Bb2 Nc6 12.0-0 0-0 13.Nce2 Rfd8 14.Bc3 Qb6 15.Kh1 d5! (Anand's equaliser: his neat idea is that after 16.cxd5 Nxd5! 17.exd5 Rxd5 the pin regains his piece  16.Nxc6 bxc6 17.Qe1! Rdc8 18.e5 Ne8 19.e6! (Carlsen throws a pawn to disrupt Anand's piece co-ordination) fxe6 20.Nf4 Bxc3 21.Qxc3 d4 22.Qd2 c5 23.Rae1 Ng7 24.g4! (Further constricting Black's pieces) Rc6 25.Nh3!! (Very unobvious: Carlsen retreats the Knight, but it's actually heading towards the King) Ne8 26.Qh6 Nf6 27.Ng5 d3? (Missing Carlsen's idea) 28.Re5! Kh8 29.Rd1 Qa6 30.a4... and Anand, to the spectators' surprise, resigned. But Carlsen will regain his pawn with Rxd3, and then will gobble up the weakling on e6. Meanwhile, the world champion's entire army is in a state of horrible paralysis.
