However, instead of long maneuvers, we will have an original game and a lot of action quickly. 12... a8c8 A good move to disrupt the natural development of the white pieces. 13. d1d2 [%c_effect d2;square;d2;type;Interesting;persistent;true] A creative move. The idea of Qd2 with the bishop on c1, followed by b3-Bb2, is known in many positions, but I admit that I had never seen this plan in a hedgehog structure. 13... d8c7 Black prepares to answer 14.b3 with b5, as now the white knight is unprotected on c3. 14. b2b3  14... b6b5 The critical move. 15. c4b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true][%cal dc7c3][%c_arrow c7c3;keyPressed;none;from;c7;opacity;0.8;to;c3;persistent;false][%c_highlight c3;keyPressed;none;opacity;0.8;square;c3;persistent;false,b5;keyPressed;none;opacity;0.8;square;b5;persistent;false,a6;keyPressed;none;opacity;0.8;square;a6;persistent;false] This is White's idea, an interesting piece sacrifice that leads to a very sharp position. All of this had already been played before by GM Kovalev. 15... c7c3  16. d2c3  16... c8c3  17. b5a6  17... b7a8  18. c1a3 White has two pawns for the piece, including doubled pawns on the a-file, but the passers are very dangerous. The position is difficult to play as Black, especially in a blitz game, despite the computer's assessment as equal. 18... d7e5 A logical move, improving the knight's position. 19. e1c1  19... f8c8  20. c1d1 [%c_effect d1;square;d1;type;GreatFind;persistent;true] The best chance for an advantage. 20... c8d8 The d6-pawn must be protected. 21. a3b4  21... c3c8  22. a2a4 [%c_effect a4;square;a4;type;Interesting;persistent;true] This seems slow, but actually it's quite interesting. White simply advances the pawns. 22... e5c6 [%c_effect c6;square;c6;type;Mistake;persistent;true] A mistake is fatal in a position as unbalanced as this. Black had to quickly seek counterplay. 23. d4c6  23... a8c6  24. b4a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] Opening the way for the b-pawn. 24... d8e8  25. b3b4 White's position is already winning, as the pawns cannot be controlled. 25... d6d5  26. b4b5  26... c6d7  27. e4e5  27... f6h5  28. a5b6  28... f7f6  29. e5f6  29... h5f6  30. a6a7  30... e6e5  31. f3f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] The most accurate. 31... d7g4  32. d1c1  32... f6d7  33. b6f2  33... d5d4  34. c1c8  34... e8c8  35. a1c1 White has many ways of winning.
