Rc2 f6 {The first deviation of the game. 12...Ba6 has been played before by Caruana (against Giri in Wijk aan Zee). Although the game was drawn, his position was a little suspicious.} 14. Qe2 Bd6 15. O-O g5 $5 {Black didn't want to capture on f4, so he forces White to capture himself!} (15... Bxf4 16. exf4 $6 {leaves the e6 pawn weak in the long run, and e5 will never be achieved.}) 16. Bxd6 Nxd6 17. Re1 a4 18. Nd2 e5 $5 19. e4 $1 {Creating serious tension on the center...} f5 $1 {A funny looking move!

Qd3 {repeating the line that Anand played against MVL earlier in the tournament.} Nbd7 {Grischuk was having none of that endgame, instead he decided to allow a knight to d5, changing the pawn structure.} 10. Nd5 O-O 11. O-O Bxd5 12. exd5 Rc8 {As is typical in the Najdorf, White exchanged a piece on d5 and how his structure has a majority on the queenside. However Black has good dark-square control and the b3 knight is very bad, it will take some time to regroup it.} 13. c4 Ne8 14. Qd2 b6 {Around here Carlsen mentioned that he didn't like his position, but to be fair there is nothing wrong with it immediately. In the long-term, however, Black's plan seems more obvious than White's.} 15. Rac1 a5 16. Na1 {No one wants to play this move, but it has a sneaky idea. Also it caused Grischuk to start thinking heavily.} g6 17. b4 $5 Ng7 (17... axb4 18. Nc2 {is the point, as the knight quickly heads to c6. Grischuk doesn't take to keep the control of b4.}) 18. bxa5 bxa5 19. Bd3 Nc5 20. Bc2 a4 21. Rb1 {White's knight on a1 is awful, but he has control of the b-file, pressure on a4 and the pair of bishops. It is hard to say who is better.} e4 $5 {Changing the position. White is happy to trade his c4 pawn for the e5 one though.} 22. Bxc5 Rxc5 23. Bxa4 (23. Qe2 $5 {is a little more ambitious} Qc7 (23... f5 $5) 24. Bxa4 Rxc4 25. Bc6 $16) (23. Bxe4 Rxc4 24. Qd3 $11) 23... Rxc4 24. Bc6 Nf5 25. Qe2 Rc3 26. Qxe4 Ra3 {White wins the pawn on e4, but thanks to this strong rook the a2 pawn is doomed. The position looks rather drawish.} 27. Qe2 Bf6 28. Nb3 Qe7 29. Qxe7 Nxe7 30. Nd2 Rxa2 31. Nc4 Rd8 {I was expecting the players to sign the scoresheets around here, but Carlsen started playing very strange moves.} 32. g4 $2 (32. Rbd1 $11) 32... Bd4 33. Rbd1 Bc5 {suddenly White is just worse. He has problems with his d5 pawn and the f2 pressure.} 34. Rd2 Rxd2 35. Nxd2 Nxc6 36. dxc6 Rc8 37. Ne4 Rxc6 38. Rd1 {The extra pawn is hard to convert, but from here on out Grischuk will torture the World Champion.} h6 39. h4 Kf8 40. Kg2 Ke7 41.
