1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... b7b6  4. g2g3  4... c8b7  5. f1g2  5... f8e7  6. e1g1  6... e8g8  7. f1e1  7... a7a5 A rare continuation, and as GM Krasenkow explained it: \"One of the useful moves. Black waits for Nb1-c3 to reply with ...Nf6-e4.\" It should be added that Rapport likes playing like this and it certainly carried the effect of the surprise. 8. c1g5 Cervantes delays the development of the knight. 8... f6e4 But the knight visits the center anyway. 9. g5e7 Played after some hesitation. 9... d8e7  10. f3d2  10... f7f5  11. d2e4  11... f5e4  12. b1c3  12... d7d5  13. c4d5 A logical novelty. 13... e6d5  14. d1b3 But that is premature. 14... e7b4 \"I just started feeling pretty good about my position, because this endgame is very comfortable for me. I feel like I can't basically lose it.\" (Yu) 15. e1d1  15... b8a6  16. a1c1 But Cervantes misses her chance. 16... b4b3  17. a2b3 The endgame is indeed very pleasant for Black and she plays it neatly. 17... a8d8 A nice prophylaxis $1 18. c3b5  18... c7c6 The d6-point is covered and the knight needs to retreat ingloriously. 19. b5c3  19... a6b4  20. c3a4  20... b7a6 Everything is coming just in time and Yu keeps the opponent's counterplay under a lid. 21. g2f1  21... d8b8  22. g1g2  22... g7g5 After putting everything in order on the queenside, Yu indicates where she will really like to attack. The half-open file as well as the space advantage will help her in the quest. 23. e2e3  23... a6d3 A small slip that allows Cervantes one more chance to complicate her opponent's task. 24. d1d2 Missing it. 24... f8f6 Protecting the c6-pawn $1 25. g2g1  25... g8f7  26. f1d3  26... b4d3  27. c1f1  27... f6f3 No more counterplay. Yu fixed a large advantage, the position is very one-sided and nevertheless, watching the young American's technique is pleasant and instructive. 28. d2c2  28... d3b4  29. c2d2  29... f7e7 Sending the weaker piece for the defense and thus releasing the more valuable attackers. 30. f1c1  30... e7d6  31. c1f1  31... d6c7 The rook is released. Yu knows she has no reason to hurry as she is strategically winning. 32. a4c3  32... b8f8  33. c3e2  33... h7h5  34. g1g2  34... c6c5 Time to bring her majority into motion. 35. h2h4 This only makes things easier for Black. 35... g5h4  36. g3h4  36... f8g8  37. e2g3  37... g8g4  38. f1h1  38... c7d6  39. d4c5  39... b6c5  40. h1a1  40... b4c6 The last move before the time control is a safe one. 41. a1c1  41... d5d4 Energetic, and not optimal this time. 42. e3d4  42... c5d4  43. c1c4  43... d4d3  44. c4a4  44... c6e5  45. a4a5  45... e5g6 The safest. 46. a5a6  46... d6c7  47. a6a4  47... g6h4  48. g2h3  48... h4f5  49. a4c4  49... c7d6
