1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 O-O 
8. c3 d6 9. h3 Bb7!? {This explains the fantastical performance of 
Karjakin in the previous round. He has done a hard work in the Zaitsev to 
play it with the black pieces.} 10. d4 Re8 11. Ng5 Rf8 12. Nf3 Re8 13. 
Nbd2 Bf8 14. a4!? {Shirov choose the tactical main line against the 
Zaitsev} 14... h6 15. Bc2 exd4 16. cxd4 Nb4 17. Bb1 c5 18. d5 Nd7 19. Ra3 
c4 
    ( 19... f5!? {Is the other option, but here white has demonstrated a 
    lot of resources to attack the weakened black's king position} )
20. axb5 axb5 21. Nd4 Rxa3 22. bxa3 Nd3 23. Bxd3 cxd3 24. Nxb5!? {After 
testing it with my database, this is suposed to be a novelty. Shirov tries
to win the pawn, however black's compensation looks more than adequate.} 
24... Qa5 25. Nd4 Qc3 26. Nf5 Nc5 27. f3!? {Weakening the black squares 
but reinforcing the "e4" square.} 27... Bxd5 {After a long think, Karjakin
opted to play for a draw} 
    ( 27... Bc8 28. Ne3 Ba6 {Was suggested by Shirov as a possible 
    variation to play for a win with black pieces.} )
28. exd5 Rxe1+ 29. Qxe1 Nb3 30. Qe8 
    ( 30. Nxh6+ gxh6 31. Qg3+ Kh8 32. Nxb3 Qxb3 {Is a kind of winning 
    attemp by Shirov, but he didn'd like it, and me too, black's pawn and 
    potential play over the dark squares looks very menacing.} )
30... Qxc1+ 31. Kh2 Nxd2 32. Ne7+ Kh7 33. Qxf8 Nf1+ 34. Kh1 Ng3+ 35. Kh2 
Nf1+ 36. Kh1 1/2-1/2

e5 9. dxe5 Ng4 10. Bxb5!! {A terrible stroke from Aronian, putting a dark 
cloud over the variation.} 10... cxb5 11. Qxd5 Rb8 
    ( 11... Ra6!? {Was suggested by Aronian as the best defence} )
12. h3 b4 
    ( 12... Nxf2!? 13. Kxf2 Bxc5 {Is another interesting option, but white
    strong central position looks impresive.} )
13. axb4 axb4 14. Ne4 Nxc5 15. Qxd8+ Kxd8 16. Nxc5 Nxf2 17. Kxf2 Bxc5 {
After a forced simplification an ending ocurred with a pawn up for white 
and initiative over the weakened "b4" pawn and the enemy king.} 18. Bd2?! 
{Aronian think that this is not the precise way for developing initiative}
18... Kc7 19. Rhc1 Kb6 20. Nd4 Rd8 21. Rc2 Rd5 22. Rac1 Be6 {Now Grischuk 
was under extreme time pressure.} 23. Nb3 Rbd8 24. Ke2 Bf8 25. Nd4 Bc5 26.

    33. Kg4 Bd4 {Is an interesting option, black appears to have 
    compensation for the exchange.} )
28... Rd4 29. Rxd4 Bxd4 30. b3 Rc5 31. Rf1 Kb5 32. Rf7 Bc3 33. Be3 Rc6 34.
 Rb7+ Ka6 35. Rb8 Ka5 36. Bg5 h6?! {Grischuk is suffering because of his 
bad bishop and the active white rook, however his position is still 
playable. Under extreme time pressure he put all his pawns in dark 
squares, which proved to be fruitless.} 
    ( 36... Bf6! {And black is very close to draw} )
37. Be7 e5 38. g4 Re6 39. Bf8 g5 40. Rd8 Rf6 41. Rd5+ Kb6 42. Rd6+ {In the
endgame black is lost because of his bad bishop} 1-0
