1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. b1c3  3... d7d5  4. c4d5  4... f6d5  5. e2e4  5... d5c3  6. b2c3  6... f8g7  7. d1a4 The Grunfeld Defense is probably the toughest variation against 1.d4. This move is one of many possible attempts to confuse the opponent. While it's impossible to prove a scientific advantage, at least White can try to pose practical problems. This strategy will succeed in the present game. 7... b8d7  8. g1f3  8... e8g8  9. f1e2  9... d7b6 This is the first important moment for opening theory. 9...c5 is also possible and was played in 2019 in a game of the highest caliber. But the move played is an even better way to equalize. 10. a4b4  10... d8d6  11. e1g1  11... c8g4 This move is rightly criticized by GM Yermolinsky in his analysis of the game Inarkiev-Li Chao. 12. b4b3 Avoiding the queen exchange. 12... g4e6 The first new move of the game. It looks strange to go back with the bishop, but Black is luring White into playing d4-d5, as this will increase the scope of the g7-bishop. 13. d4d5  13... e6g4  14. h2h3 This is not the most accurate. White can fight for an advantage with 14.Rb1 or 14.Rd1. 14... g4f3  15. e2f3  15... c7c6  16. c1a3  16... d6c7 Too passive. Muzychuk misses the chance to setup a battery with queen and bishop that threatens the white king. Of course, it's always easy to decide on such matters with an engine turned on, as there is an important and difficult to find detail in the following variation. 17. a1e1 A subtle move, anticipating the capture on d5. However, this is not the best attempt. 17... c6d5  18. e4d5  18... g7f6  19. e1e4 A nice move, preparing to double rooks on the e-file and also supporting the advance of c3-c4. Moves with more than one idea are usually the best in chess, unless you analyze the position deeply with the computer. The machine crushes all dreams of a logical explanation and usually shows the way to equalize, no matter what. 19... f8c8  20. f3g4  20... c8d8  21. c3c4 Now White is positionally winning. Lei has everything she could ever dream of achieving against the Grunfeld: bishop pair, more space, and moving pawns. 21... h7h5  22. g4e2  22... a8c8  23. f1e1  23... d8d7  24. g2g4 A lovely move. I enjoy these pawn advances in front of the king very much, since they usually come as a surprise. 24... h5h4  25. b3e3  25... g6g5 Necessary, in order to avoid 26. g4-g5. 26. e2d3 Now the e7-pawn falls. 26... b6a4  27. a3e7 The simplest. 27... d7e7  28. e4e7  28... c7e7  29. e3e7  29... f6e7  30. e1e7  30... a4c5  31. d3f5  31... g8f8  32. e7f7  32... f8f7  33. f5c8 White is two pawns up, and the rest is easy. 33... b7b6  34. c8f5  34... f7f6  35. d5d6  35... c5b7  36. d6d7  36... f6e7  37. f2f4  37... g5f4  38. g1f2  38... b7d6
