1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8c5 The Arkhangelsk Variation, one of the favorite lines of the likes of Aronian, Caruana, Anand, and Shirov. 6. c2c3  6... b7b5  7. a4b3  7... d7d6  8. d2d4 The main direction. 8... c5b6  9. c1e3  9... e8g8  10. b1d2  10... h7h6  11. h2h3  11... f8e8 All of this has been seen before with Black planning to put the opponent's center under concrete pressure. 12. f1e1  12... e5d4 A very concrete approach, typical for the line. 13. c3d4  13... c6b4 Keymer went into the think tank from here and spent almost an hour on his next three moves. 14. d1e2 The first major thought by White. Dominguez deviates from a known top-game. 14... c7c5 Now it gets very messy since Keymer has no choice but to challenge the enemy center. 15. a2a3  15... c5c4  16. a3b4  16... c4b3  17. e2d3  17... f6e4 A temporary sacrifice and the center is at last ruined. 18. e3h6  18... c8f5  19. e1e4 Apparetly, an over-the-board novelty. 19... e8e4 I think Keymer chose right $1 Now the forcing line continues further. 20. d2e4  20... d6d5  21. h6g5  21... d8d7  22. e4c5  22... b6c5  23. d3b3  23... c5f8 The end of the tactical skirmish. White won a pawn, but Black has ample compensation thanks to his bishop pair. Still, White can push, relatively risk-free and this is what he is doing. 24. f3e5  24... d7e6  25. a1e1 Th correct approach. If White wants to play for a win, he will need some major pieces alive. 25... a8c8  26. g5d2  26... f5c2  27. b3g3  27... f8d6  28. g3a3 A nasty transfer from one side to another. It seems as if White managed to disrupt the harmony in the enemy camp. 28... c2e4 But Keymer quickly consolidates. 29. f2f3  29... e4f5  30. e5c4 At least depriving the opponent of the bishop pair. 30... e6g6  31. c4d6  31... g6d6  32. a3e3  32... d6g6  33. g2g4  33... f5d7
