csmath: 6. Bg5
[Three Knights sideline not played on the top level.]8. Rc1
[Typical Exchange Grunfeld position with only one difference, early placement of bishop on g5.] 8. ...Bg4?!
[Natural move although 8. 0-0 would have been more in the spirit.] 13. ...b5?!
[Critical moment of the game. Black has problem developing knight but this sacrifice seems ad hoc and ill prepared. 13. ...Rd8 14. h4 h6 15. Bf4 Qa5 16. Bc4 b5 17. axb5 axb5 18. Bxc3 19. Kf1 Bf6 20. Rxc5 Na6 21. Rc1 Rdb8! 22. Rb1 Nc7 is better.  click for larger view

16. c4?!
[16. Bf4! Be5 17. Bxd7 Bxf4 18. Bc6 Rab8 19. Qc2 leaves white with a pawn (19. ...Bxh2?! is a bad idea as after 20. f4 black will need to sac the piece).] 16. ...Ne5

18. f4

18. ...Ng4?
[18. ...h6! is typical given the black bishop is now poorly placed. Possible continuation 19. fxe5? hxg5 20. e6 h4 21. g4 gives black serious advantage. White could also play 19. Bh4 Rfa8! 20. Bg3 Ra3 21. Qb1 Nd3 22. Rcd1 Qc8! 23. Rxd3 Ra1 with advantage for black:  click for larger view
] There are moments in Grunfeld where black has to be creative and precise. Caruana missed this moment and now it is all downhill for him. 21. Bxf6
[Forced as black is planning Ra3.]
Mamedyarov will consolidate his position securing the king and keeping the pawn. This clearly spells trouble for black. 29. Rf1
 click for larger view29. ...Rf6?!
[...g5! is more precise with the same idea of pressure on f2. After 30. f5 (what else) ...Qb8! planning Qe5 and black still has some compensation for the pawn. The move Caruana played commits rook on a dangerous square.] 30. Qb3
[This is exactly the consequence of bad 29th move of black. However this is not as dangerous as it looks.] 30. ...Rb7?
[30. ...Re2! 31. Qd3 Ra2 32. Rd2! and now f2 is secured.]  click for larger viewHere black is close to being strategically lost. He has no countergame and he is pawn down. However there is a long way to prove that white should win this as the position is still very much playable and black could hope. 35. ...Bh4
[...Rg6 leaving f6 square free for bishop is the same.] 42. Rb1
[Of course not 42. h4? Qg4.]
43. ...Rxg1?!
[...h6 44. Qh5 Bf6 seems more persistent at least if not better. Strong defender would surely do the best to annoy his opponent. Caruana seems to be resigned to play the ending.] Now the remainder of the game is with a lot of manouvreing with black on the verge of defeat but the technical issues for white allow the black to contemplate half a point. 61. e4!
[Since white had no better plans he is trying to change the character of the position. This move is actually not winning but white cannot lose.] 61. ...Qc3
62. Qf7 [with mate threat.] Qxc3
63. Kg4 Qe2
64. Kf5 h5
