1. d2d4  1... d7d5  2. c2c4  2... e7e6  3. b1c3  3... f8b4 Yu decided to surpise her opponent in the opening and, strictly speaking, the outcome was well beyond expectations. 4. d1b3 \"This was already no preparation.\" (Zatonskih) She remembered that four years ago at the Cairns Cup Harika had also opted for 3...Bb4 against her, but that was all... 4... b8c6 Yu also started to think deeply from here onwards, and the result of this strategy of trying to outwit your opponent was serious mutual time-trouble at the end. 5. g1f3  5... a7a5  6. e2e3  6... g8e7  7. c1d2  7... e8g8 [#] 8. a2a3 A logical move, and a novelty. This is a good moment to trade the strong bishop. 8... b4c3  9. d2c3  9... b7b6  10. f1d3  10... c8a6  11. e1g1 For a while, White considered immediate play in the center, but as a strong classical player she decided to finish her development first. 11... a5a4  12. b3a2  12... d5c4  13. d3c4  13... a6b7 Starting a risky approach. Yu allows her opponent to seize the center. 14. e3e4  14... c6a5  15. c4d3  15... e7g6 But then Black quickly counter-attacks it. Now everything will depend on the ability of White to hold on to the strong center. If it collapses, it will be Black who seizes the initiative on the kingside. 16. f1e1  16... g6f4  17. d3c2  17... f7f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] Time is key here, and this aggression is fully justified. 18. c3d2  18... f5e4  19. c2e4  19... b7d5 Suddenly, the game has opened up and now any mistake might be the last. White hopes that her central control will be enough to repel any counter-attack, whereas Black in turn believes that the opponent's pieces might be a little too far to come to the assistance of the white king. 20. a2b1  20... a5b3 A very logical idea, to get this piece back into the game, but not the best one.... 21. d2f4  21... f8f4  22. e4h7  22... g8f8 [%c_effect f8;square;f8;type;GreatFind;persistent;true] Now the king moves to a safer square. 23. f3e5 The culmination of the game. 23... f4d4 And a blunder $1 24. b1g6 [%c_effect g6;square;g6;type;GreatFind;persistent;true] Yu might have missed this strong intermezzo. 24... d8e8  25. g6g3 [%c_effect g3;square;g3;type;GreatFind;persistent;true] This is the thing—now Zatonskih keeps both her material and the attack. 25... a8a7  26. e5g6  26... f8f7  27. a1d1 [%c_effect d1;square;d1;type;GreatFind;persistent;true] Another powerful move. 27... c7c5  28. d1d4  28... b3d4  29. g3f4  29... d4f5  30. g2g4 Winning the knight and the game. 30... e8d8  31. g4f5  31... d8f6  32. f5e6  32... d5e6  33. g6h8  33... f7e7  34. h7f5  34... g7g5
