Bb4 Rb8 26. c4 $2 {Actaually it would have been better to pass than play this move; Dominguez forgets that the reason that Black cannot go Be8 is thanks to Qc4+.} (26. Nh4 $1 g6 27. h3 $16 {provoking the weakness on f6 is important as Bxc5 becomes a threat in several lines.}) 26... Be8 $1 {White's rook is in some problems since White doesn't have Qc4+ any more.} 27. Bxc5 Bxc5 28. Ra6 Qb7 29. Nb3 {Now Black's pair of bishops give him very real chances to hold on.} Bb4 30. Ne1 c6 31. Nd3 cxb5 $1 {Nice. The calculation for this is simple and it forces the draw.} 32. Nxb4 bxc4 33. Qxc4+ Bf7 {White's up a piece, but obviously that will not be true for long.} 34. Nd5 (34. Nd5 Bxd5 35. Qxd5+ Qxd5 36. exd5 Rxb3 $11) 1/2-1/2

Nf3 e6 5. Be2 Nd7 6. O-O {Black has tried every move here, basically, including Ne7 (main line), h6, bg6, c5, be7, qc7.. but Jobava always finds ways to come up with a move no one has thought of. h5 earlier in the tournament wasa disaster, so he goes for a different style.} f6 {Probably objectively bad as Black doesn't seem developed enough for this break. However proving it over the board is not so easy.} 7. c4 (7. Bd3 $5) 7... fxe5 8. dxe5 Bc5 9. Nc3 a6 10. cxd5 cxd5 {Black is very close to finishing his development, and if he manages to do that he should be quite happy with his position. The blockade on d4 won't hold... unless Svidler gives up his structure.} 11. Be3 $5 {cementing White's hold over d4 at the cost of a long term weakness on e3 and e5.} Bxe3 12. fxe3 Ne7 13. Qb3 Qb8 14. Qa3 { Svidler doesn't even try to hold on to his pawn, instead he wants to develop an initiative that will keep Black's king in the center.} Nxe5 15. Nd4 N5c6 16. Nxf5 (16. g4 $5 Nxd4 17. exd4 Bg6 18. Na4 {kept quite a bit of compensation now that Black cannot castle kingside and White's knight is threatening to go to c5.}) 16... exf5 17. Bf3 Qe5 18. Qc5 O-O-O {of course, castling long doesn't look particularly safe, but Black is trying to get his king to the corner and then push White back. His development is almost finished.} 19. Rfd1 Kb8 20. b4 Rd6 $1 {This is a key resource, and a superb fine from Jobava. Thanks to this rook lift Black is able to beat White's attack back.} 21. b5 Rc8 $1 {This is the point. The knight on c6 is untouchable and taking on a6 does not work either.} 22. Rac1 (22. bxc6 Rdxc6 23. Qd4 Qxd4 24. Rxd4 Rxc3 $19) (22. bxa6 Nd8 $19 {The knight on d8 protects b7 against any checkmating threat, so the c3 knight is simply hanging. a7+ doesn't work since the knight on e7 is still defending the c8 rook.}) 22... Na7 23. Qa3 axb5 24. Ne2 Rxc1 25. Rxc1 Nac6 {White simply doesn't have enough for two pawns. Black is consolidating and the rest is easy for Jobava.} 26. Qc5 g5 27. h3 b4 28. a3 Re6 29. Kf2 d4 30. exd4 Qxc5 31. dxc5 {Transformatino of advantages. White wins a pawn, but it is temporary, and Black has all the pluses in the position now, including activity.} Ne5 $1 (31... Ne5 32. Ra1 Ra6 33. a4 Nd3+ {is a clean two extra pawns.}) 0-1
