1. e2e4  1... c7c5  2. b1c3  2... b8c6  3. f1b5 A popular subvariation for those who don't like opening the game against the Sicilian. 3... c6d4  4. b5c4  4... e7e6  5. g1e2  5... a7a6  6. a2a4  6... g8f6  7. e1g1  7... d7d5  8. e4d5  8... e6d5 It's clear that Black has absolutely no problems in this position. 9. c4a2  9... d4e2  10. d1e2  10... f8e7  11. d2d3  11... e8g8 [%c_effect g8;square;g8;type;Inaccuracy;persistent;true] This allows White to win a pawn. 12. c3d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 12... f6d5  13. a2d5  13... d8d5  14. e2e7 Black is close to equality thanks to his activity and the opposite-colored bishops. But I'd rather have equality being a pawn up than a pawn down. 14... c8e6  15. e7g5  15... d5g5 Only now does the game take a unique character. 16. c1g5  16... f7f6  17. g5e3  17... c5c4  18. d3c4  18... e6c4  19. f1e1 The endgame has a great tendency for a draw, but White can press without any risk. That's a pleasant feeling for a chess player—you know you're going to have your opponent defending for hours, and the worst that can happen is to get a draw. 19... b7b5  20. a4a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] When you have a material advantage in an endgame, keep the pawns on the board. This is a classic rule that has multiple exceptions, but it's still good to know. 20... f8e8  21. a1d1  21... a8d8  22. d1d8  22... e8d8  23. f2f3  23... g8f7 Black will play the endgame very passively, and that will be the problem. In the next few moves, it's possible to try an active plan, playing b4 and then b3 or Rd5. 24. g1f2  24... h7h5  25. h2h4  25... c4e6  26. e1c1  26... d8c8  27. f2e2  27... c8c4 [%c_effect c4;square;c4;type;Inaccuracy;persistent;true] 28. g2g3  28... c4c8  29. e3d4  29... c8e8  30. e2e3  30... e6d5  31. e3f2  31... d5e6  32. c1g1  32... e6f5  33. c2c3 [%c_effect c3;square;c3;type;GreatFind;persistent;true] Even after this move, Black might consider playing b4, as it's not so bad to lose the pawn as long as the bishop can blockade the queenside pawns. 33... f5c8  34. d4b6  34... e8e7  35. b6e3  35... c8e6  36. g3g4  36... h5g4  37. f3g4  37... e7c7 [%c_effect c7;square;c7;type;Inaccuracy;persistent;true] Muzychuk keeps waiting, but this strategy costs her the game. 38. g4g5 Now it's getting really dangerous. 38... c7c4 [%c_effect c4;square;c4;type;Mistake;persistent;true] The decisive mistake. 39. g5g6 [%c_effect g6;square;g6;type;GreatFind;persistent;true] After this move, the pawn structure on the kingside is annoying for Black, and it's no longer possible to save the game. 39... f7e7  40. e3d4  40... c4c8  41. f2g3  41... e6d5  42. g1e1  42... e7d7  43. e1d1
