1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. d2d3  4... f8e7  5. e1g1  5... e8g8  6. b1c3  6... d7d6  7. a2a4  7... c6a5  8. c4a2  8... a5c6 [%c_effect c6;square;c6;type;Interesting;persistent;true] A curious move. Much more natural is to advance the pawn to c5; no wonder it's the move played most often. But Muzychuk's idea is to take the knight to b4, gaining a tempo thanks to the positional threat of capturing the bishop, and only then to take the pawn to c5. 9. c1d2 This was played by Praggnanandhaa in a rapid game. 9... c6b4  10. a2b1 A new move. This looks like an awkward square for the bishop, but White is planning Ne2 and then c3, when the bishop can go to c2 or a2. 10... c7c5 Both players continue with natural moves, improving their positions. 11. h2h3  11... f8e8  12. c3e2  12... b4c6  13. e2g3  13... h7h6  14. f1e1  14... c8e6 Black has finished development and has a more comfortable position. 15. c2c3  15... a7a6 [%c_effect a6;square;a6;type;Interesting;persistent;true] An interesting prophylactic move with the idea of reducing the impact of the b2-b4 advance. 16. d2c1 This seems very passive, but actually it's a good move with the idea of playing d3-d4. 16... a8c8 Useful so that the rook can act on the c-file after d3-d4. 17. b1c2 [%c_effect c2;square;c2;type;Inaccuracy;persistent;true] White is unsure of what to do. The worst nightmare for a chess player is to be left without a plan. 17... e7f8  18. c2b3  18... d6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] Black achieves the always desired central break. 19. e4d5  19... e6d5  20. g3e4  20... d5b3  21. e4f6  21... d8f6  22. d1b3  22... c6a5  23. b3c2  23... c8d8 Muzychuk is playing excellent positional chess, reinforcing her position. It's not easy for White to protect the weak d3-pawn. 24. c1d2  24... f6f5  25. e1e4 [%c_effect e4;square;e4;type;Mistake;persistent;true] This is met by a clever tactical idea. 25... c5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] This is essentially a winning move. Black wins either a pawn or an exchange. 26. a1e1  26... c4d3  27. c2d1  27... f7f6 Now Black is a solid pawn up. 28. b2b4  28... a5c6  29. b4b5  29... a6b5  30. a4b5  30... c6e7  31. d1b3  31... g8h7  32. b3f7  32... f5g6  33. f7c4  33... e7f5 The knight is ready to go to d6. 34. f3h4  34... f5h4  35. e4g4  35... d8c8 [%c_effect c8;square;c8;type;GreatFind;persistent;true] 36. c4a4  36... c8a8  37. a4d1  37... g6f5  38. g4h4  38... f8c5  39. e1f1  39... a8a2 The rest is easy: Black is not only a pawn up but has an overwhelming positional advantage. 40. h4a4  40... a2c2  41. g2g4  41... f5d7  42. a4e4
