1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. d2d3  4... f8c5  5. e1g1  5... a7a6  6. c2c3  6... c5a7  7. c4b3  7... d7d6 Both players interpret the Italian Opening in one of the most classical ways possible. Everything is natural and logical. 8. f1e1  8... e8g8  9. b1d2  9... h7h6  10. d2f1  10... c8e6 There is an old question here about which is better, playing this move immediately or preparing it with ...Re8 first. 11. b3e6 11.Ng3 is more popular, but the move in the game is a thematic attempt to exploit the move ...Be6 when Black has to capture with the pawn. 11... f7e6 A typical pawn structure in this opening. 12. c1e3  12... a7e3  13. e1e3 An important position for opening theory and understanding. 13... d6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] A strong opening novelty and the first choice of the computer. The move appears to be dangerous both tactically and strategically, as it leaves the pawn on e5 weak, and it even runs the risk of being captured immediately after the 14.exd5 exchange. However, as is well known, generic concepts are not the most important thing in chess. Concrete calculation has the supremacy and here it proves that everything works. Black will have good development after the queen arrives on the d6 square, which has become available. Other moves fail to equalize completely. 14. d1b3  14... d8d6  15. a1e1  15... d5d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] 16. c3d4  16... e5d4  17. e3e2  17... f6h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] The point of Black's play: the knight can go to f4, but the real threat is a thematic exchange sacrifice on f3. 18. e2c2 Aronian is not afraid. 18... f8f3 [%cal af8f3][%c_arrow f8f3;keyPressed;alt;from;f8;opacity;0.8;to;f3;persistent;false][%c_highlight f3;keyPressed;none;opacity;0.8;square;f3;persistent;false] This move seems irresistible, but Keymer had to calculate very precisely to demonstrate its viability. Perhaps the alternative 18...Nb4 is simpler. 19. b3b7  19... c6b4 [%c_effect b4;square;b4;type;Brilliant;persistent;true] The only way to justify Black's previous move. 20. g2f3  20... d6f8 [%c_effect f8;square;f8;type;GreatFind;persistent;true] Again the only move $1 Razor sharp calculation. 21. c2c7  21... a8b8  22. b7a7  22... b4d3  23. e1d1  23... d3e5  24. d1c1  24... g8h7 [%c_effect h7;square;h7;type;GreatFind;persistent;true] A good prophylactic move, preventing Qxb8 followed by Rc8+. 25. a7c5 [%c_effect c5;square;c5;type;Mistake;persistent;true] This loses. 25... f8f6  26. f1g3  26... e5f3  27. g1h1  27... f3e5  28. g3h5  28... f6f3  29. h1g1  29... f3h5 White is helpless against the attack of the queen, knight and rook. 30. h2h3  30... b8b2 [%c_effect b2;square;b2;type;GreatFind;persistent;true] The last piece joins the attack.
