Nf3 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. dxc3 {This endgame had only a couple of years of popularity a long time ago. It is very slightly better for White, but at some point people realized that if Black goes f6 and e5 he should equalize.} Qxd1+ 7. Kxd1 f6 8. Be3 e5 9. Nd2 Be6 (9... Nd7 {was Bogner-Li Chao from 2014. The Chinese player won that game.}) 10. Bc4 Kf7 11. Kc2 Be7 12. Rad1 {Technically the novelty of the game, though the last time any other move was played was back in 1991...} Rd8 13. Bxe6+ Kxe6 14. Nc4 Rxd1 15. Rxd1 Nc6 16. a4 {White has very little in this endgame... perhaps not even that. It seems that Topalov was ok with playing a position without any kind of advantage, perhaps even heading to a draw after two consecutive losses.} a5 17. f4 h5 18. Rf1 exf4 19. Bxf4 Ne5 20. Bxe5 fxe5 {The knight has no advantage over the bishop, and vice versa. The game is bound to be drawn in this position as there is nothing to attack.} 21. Rf3 b6 22. Rg3 Rg8 23. Kd3 Bh4 24.

Black has already expanded on the queenside, and has his knight on d7, which has always made me think that his position is superior to a normal Spanish.} 10. Rd1 Qc7 11. a4 Rb8 (11... Bb7 {was also possible, after} 12. d5 c4 {Black has some kind of Breyer type of counterplay after Nc5.}) 12. axb5 axb5 13. Na3 Ba6 {Apparently MVL missed the idea of d5 followed by b4, which perhaps gives White a minimal advantage, but it isn't anything exciting.} 14. d5 Qb7 15. b4 Bd8 $1 {Remaneuvering the bishop is Black's best bet in keeping equality.} 16.

Qxb6 Nxb6 {White's space advantage doesn't matter much here. It's too difficult to create any kind of play. The game is eventually drawn after this.} 23. g3 Nf6 24. Ng2 Ne8 25. Ra2 Bc8 26.

Nc4 Nd7 9. b3 a5 10. a4 f6 {This typical exchange Ruy Lopez type of structure has become more common as people are trying to avoid the endgame. However, it's hard to say what White has in this position. He has no real pressure and Black has the pair of bishops. The awkward pawn structure is too vague to be exploited.} 11. Be3 Bb4 12. Rc1 b5 13. c3 Bf8 14. Nb2 {Somehow I'm not convinced about putting a knight on b2.} Nc5 15. Qc2 Bg4 16. d4 exd4 17. Nxd4 bxa4 18.

Still difficult for Black to win since the bishop on f8 is so bad.}) 25. c5 $1 {An important move, killing the bishop on f8 and making it hard for the knight on b7 to rejoin the game.} Nd8 26. Nb2 Ne6 27. Nc4 Bxc5 (27... a4 $5 28. bxa4 Rxa4 29. Nb2 Nxd4 30. Bxd4 {is hard to make progress, but White just needs to defend and hope his fortress holds.}) 28. Nxe6 {A queen sacrifice.} Bb4 29.

Rxc6 {Anand didn't want to play this, but he figured every pawn he took was a good thing.} (33. Nc4 Bxc4 34. Rxc4 Qb7 35. Rc3 {is also close to a fortress.}) 33... Qd7 34. Rc2 Re8 35. Nc4 Bxc4 36.

Nb3 {was less than nothing for White in Carlsen-Leko, 2009.}) (15. b3 {was maybe better than the game continuation, as in Negi-Sargissian, 2011.}) 15... Nd7 {Aronian first long think makes sense. The knight reroutes to c5 where it will pressure e4 after kicking out the bishop on d3. Also the a6 pawn will get another defender.} 16. b3 Nc5 17. Bc4 Be6 18. Bb2 f6 19. Bxe6+ Rxe6 20. Nc4 Rb8 21.

Nd5 O-O 11. O-O Bxd5 12. exd5 Rc8 {As is typical in the Najdorf, White exchanged a piece on d5 and now 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 immediately wrong with it. 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 causes 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 declines from taking in order to keep 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.
