And White finished the game in the most artistic way with
1. e2e4  1... c7c6  2. d2d4  2... d7d5  3. e4d5  3... c6d5  4. f1d3 The Exchange line that Fischer revived in the 1970s lives a new life thanks to the rise of the London System. A lot of positions transpose from both the openings and the pawn chains are quite similar. 4... g8f6  5. h2h3 Underlining Black's major problem in the position: the future of his light-squared bishop. 5... b8c6  6. g1f3  6... c6b4  7. b1c3 This is quite an interesting sideline, but should not have come as a major surprise. Aronian is playing his Ragozin with colors reversed. 7... g7g6 Still trying to solve the bishop problem. 8. f3e5  8... a7a6  9. e1g1  9... f8g7  10. f1e1  10... e8g8  11. c1g5 White's plan is very easy and straightforward: bring the queen out, trade the dark-squared bishop, and mate on the kingside. 11... b4d3 Lines like the above-mentioned forced Keymer to make up his mind. 12. c2d3 Played without any thought $1 Aronian is already envisioning perfect domination with the beautiful knight pair on the c5- and e5-outposts. 12... d8b6  13. e5f3 A strong reaction $1 13... e7e6  14. c3a4  14... b6d6  15. d1d2 Aronian's opening choice was a huge success. He managed to smother the opponent's light-squared bishop and is in full charge of the dark-squares. 15... a6a5  16. a1c1  16... c8d7 Keymer was counting on this natural development to force the active knight back, but he was about to be unpleasantly surprised. 17. a4c5  17... b7b6 It seems the knight needs to retreat... 18. g5f4  18... d6e7  19. c5d7 But no, Aronian plays instead in the spirit of the famous Fischer-Petrosian game and is voluntarily parting with his amazing knight. 19... f6d7  20. c1c7  20... f8c8  21. e1c1  21... e7d8  22. d2c2 That is the price for the good knight: the only open file is in Aronian's hands and he infiltrates with his major pieces. 22... c8c7  23. c2c7  23... d8c7  24. c1c7  24... a8d8  25. c7b7 The black pawns are beautiful, but it is the activity of the pieces that comes first when evaluating these positions, and the difference there is horrendous. 25... g8f8  26. f4d6  26... f8e8  27. f3e5 Another strong move, completely paralyzing the opponent. 27... g7e5  28. d4e5 Ironically, instead of a pair of perfect knights White got the domination of a bishop versus a knight, and perfect pawn structure $1 28... d8c8 After this Keymer stands no chance. 29. d3d4  29... e8d8  30. b7a7 Now after some final preparation 30... c8c4  31. b2b3  31... c4c1  32. g1h2 White improves his king. 32... h7h6  33. h2g3  33... c1c3  34. f2f3  34... c3c6 And finally creates a second weakness with 35. h3h4  35... c6c8  36. h4h5  36... c8c6  37. g3h4  37... c6c8  38. g2g4  38... d8e8  39. f3f4  39... e8d8  40. h5g6
