1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. d2d3  5... f8c5  6. c2c3  6... b7b5  7. a4b3  7... d7d6  8. c1g5 This is a treacherous move. White invites the opponent to play the classic plan with h6-g5, leading to a sharp position. 8... h7h6  9. g5h4  9... c8d7 A rare choice. Two of the best chess players in the world decided to move the dark-squared bishop in this position, but they played it on different squares. 10. b1d2  10... d8e7  11. e1g1  11... g7g5  12. h4g3  12... c5b6 A new move, although the bishop retreat is necessary sooner or later. 13. a2a4 A typical move in the Spanish, opening the a-file. 13... a8b8  14. a4b5  14... a6b5  15. f1e1 These positions are difficult to play for both sides. Here, for example, Black has a dilemma: should he advance the kingside or castle $2 Apparently we have yet another case of the \"when in doubt, just castle\" principle. 15... h6h5 [%c_effect h5;square;h5;type;Inaccuracy;persistent;true] 16. h2h4  16... g5g4  17. f3h2 [%c_effect h2;square;h2;type;GreatFind;persistent;true] The right square. Sometimes you have to go back before going forward. 17... f6h7 [%c_effect h7;square;h7;type;Inaccuracy;persistent;true] 18. h2f1  18... h7f8  19. f1e3  19... b6e3  20. f2e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] Reinforcing the center and opening the f-column. 20... f8g6  21. e1f1  21... d7e6  22. b3d5  22... c6d8  23. a1a7 [%c_effect a7;square;a7;type;Interesting;persistent;true] Starting a very creative idea. Aronian is one of my favorite chess players; he has very deep strategic ideas. 23... g6h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] Sevian rightly accepts the complications. 24. a7c7 [%c_effect c7;square;c7;type;GreatFind;persistent;true] A beautiful tribute to Tigran Petrosian, the king of the exchange sacrifice. 24... h4f3  25. d2f3  25... e7c7  26. f3h4 White doesn't have even a pawn for the exchange, but his pieces are well placed, and the black king is in danger. It is worth noting the weakness of the dark squares. 26... d8c6  27. h4f5 [%c_effect f5;square;f5;type;Inaccuracy;persistent;true] There are better alternatives. Both 27.Rf6 and 27.d4 are very promising. 27... e6f5  28. f1f5  28... h5h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] Another accurate move. 29. f5f7 [%c_effect f7;square;f7;type;Inaccuracy;persistent;true] 29... c7f7  30. d5f7  30... e8f7  31. g3e1  31... h4h3 [%c_effect h3;square;h3;type;Mistake;persistent;true] Sevian advances the wrong pawn, and now his position becomes not defendable. 32. e1g3 [%c_effect g3;square;g3;type;GreatFind;persistent;true] White's king is well protected now, and the bishop becomes active, especially after the move d3-d4. Black's king and pawns, on the other hand, are vulnerable.
