Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. f3 {Dominguez usually prefers this move order over 6.Be3 to prevent 6...Ng4.} Qb6 $5 {One of the new options available for Black now that White played 6.f3. This leads to highly complex play as White has some problems developing along the darksquares, but the queen on b6 can become a target.} 7. g4 (7. Nb3 {is more common.}) 7... Nc6 8. Nb3 e6 9. Qe2 Qc7 10. Be3 b5 11. O-O-O Nd7 12. Qf2 Nce5 13. Rg1 {Dominguez is the first to deviate, not waiting to see what Mamedyarov had in store.} (13. Kb1 Be7 14. Rg1 g5 $5 {led to a complicated game in which the Cuban played annihilated the Azeri in Dominguez-Mamedyarov, Tromso Olympiad 2014.}) 13... Rb8 14. a3 $5 {This seems to invite b4, but that move is actually not possible. } Bb7 (14... b4 15. axb4 Rxb4 16. f4 Nc4 17.

Both sides are trying to push their idea: Black has opened the b-file for his rook as well as trying to open lines for his bishops, meanwhile White is trying to punish Black's uncastled position.} dxe4 20. fxe6 fxe6 21.

Not only that, he has some positional pluses, including play against the isolated e-pawn.} Kf7 28. Ned2 (28. Ncd6+ Kg8 29. Qg3 {was more incisive.}) 28... Kg8 29. Ne3 Rc8 30. Qg3 e5 31. Nb1 Be6 32. Nc3 Ng6 33. Ned5 Qf7 34. Qe3 Qf5 35. Ne4 Rf8 36. b3 Qg4 37. Ndc3 Nf4 38. Kb2 {White has taken a roundabout way of consolidating, but now he has blockaded the e-pawn and his king is in relative safety. Dominguez is on his way to win this game, or so it seems.} Bf5 39. Rd2 (39. Nd6 $1 Qxg5 40. Qxe5 $18) 39... Ne6 40. Nd6 Qxg5 41. Re2 $2 {This move is simply hard to explain.} (41. Nxf5 Qxf5 42. Qb6 {leads to winning advantage since after taking on a6 White will have three passed pawns.}) (41. Qxg5 Nxg5 42. Nd5 {was a stronger way of exchanging queens as now the knights control the board. Black will have trouble holding on to his pawns.}) 41... Qxe3 42. Rxe3 Nd4 {now there is counterplay against c2 and it is not trivial to win this position at all.} 43. Rxe5 $2 (43. Nce4 $14) 43... Bxc2 44. Rd5 Rf4 {perhaps Dominguez underestimated this move, but Black is now out of the dangerous waters.} 45. Nce4 Bxe4 46. Rxd4 Rf2+ 47. Kc3 Bg6 48. h4 Rf3+ 49. Kb4 Bc2 50.
