1. d2d4  1... g8f6  2. c2c4  2... c7c5  3. d4d5  3... g7g6  4. b1c3  4... f8g7 Krush does not hide her intentions. This is a must-win situation for her, the color of the pieces does not matter. 5. e2e4  5... d7d6  6. f2f4 Nor does Yu hide her intentions. She is transposing into the Four Pawns Attack, one of the most aggressive ways to fight the KID. 6... e8g8  7. g1f3  7... e7e6  8. d5e6  8... f7e6  9. f1e2  9... b8c6  10. e1g1  10... b7b6 Played after serious thought. The long diagonal is very tempting for the bishop, especially now that the white one is not taking care of the e4-pawn. 11. f3e1 And this novelty has been played after an even heavier thought (more than 22 minutes on the clock). 11... c8b7 With the white knight away from the g5-square this is more than justified. 12. c1e3  12... c6d4 Krush is comfortably developing and does not experience any problems whatsoever. 13. e2d3  13... d8e7 A natural move. The rooks are connected. 14. e1c2  14... f6d7 Both sides are preparing for the grand central battle. 15. a1b1 Overprotecting the b2-pawn. Yu likely believed that she will have the time to deal once and for all with the active black knight and removed from the scene with Nc3-e2, but that is too slow. 15... f8f7  16. d1d2 Yu is demonstrating her mental power and admits her mistake. Unfortunately for her, this costed her another 11 minutes on the clock. 16... a8f8  17. b1e1  17... e6e5 Krush decided that the time had come. 18. c3d5 The most obvious move is not the best one here. Now Black would claim large advantage. 18... b7d5  19. e4d5  19... d4c2  20. d3c2  20... e5f4  21. f1f4 A critical moment. 21... f7f4 Krush chooses a complicated way. 22. e3f4  22... g7d4  23. g1h1  23... e7f6  24. g2g3  24... d7e5  25. d2e2  25... d4b2 Finally Krush won the pawn, but Yu managed to consolidate her position and White's active pieces control a lot of squares. 26. h2h4  26... b2d4  27. h1g2  27... f6e7  28. e1f1  28... e7d7 Immediately trying to capitalize on the inaccuracy. 29. f4e5 Once again Yu demonstrates flexible thinking. So far it has never been a good idea to swap off this bishop for the knight as Black was always enjoying the better bishop and therefore the better attacking chances. But the last few moves have changed the situation and it is White who can start an attack before the opponent in many lines. 29... f8e8 Krush keeps playing for the win. But this is a blunder, which suddenly leads to... 30. e2f3  30... d4e5  31. c2a4 And it all ended with an even bigger blunder. Yu deflected the queen from the defense of the f7-square, that is true, but in time-trouble she forgot that the black queen defends the rook from afar. 31... d7a4  32. f3f7  32... g8h8 Everything is defended and the desperate time-trouble attack does not help. 33. h4h5  33... g6h5  34. f1f5  34... e5d4  35. f5g5  35... a4c2  36. g2h3  36... c2e4
