The game can progress:} O-O 11. Rd1 Nb4 12. Bg5 h6 13. Bxf6 Bxf6 14. Ne4 Be7 15. Ne5 {With chances for both sides; White's pieces are more active and she can look towards attacking the kingside, but Black has the two bishops and potential play against the IQP. }) 10... exd5 11.

Ju ends up exploiting the king's slightly inferior position and it never finds it way back to the safety on g8.} (19... Rxf8 {Seems more natural to me. The game can possibly continue with:} 20. Rad1 (20. Qb5 Bxd5 21. Qxd5 Rd8 22. Qe4 Bf6 {And Black has a fine position.}) 20... Bxd5 21. Rxd5 Qc6 22. Qb5 Qxb5 23. Rxb5 b6 24. Kf1 Bf6 25. Ke2 Rd8 {While White has some pressure, Black should be fine as long as a5 isn't allowed} 26. b3 Bc3) 20. Qb5 Bxd5 21. Qxd5 Rd8 22. Qe4 {Now Black's position is significantly harder to play than four moves ago. Goryachkina is forced to make concessions on the kingside; moreover, the Black queen is tied down to the pawns on the queenside while its counterpart is placed perfectly in the center} h6 23. g3 (23. Qh7 {A natural move, but after:} f6 {There are no attacking prospects since White doesn't have enough pieces. Plus, White's queen is better centralized.}) 23... b6 24. Rc1 {Rooks on open files!} f6 { Not the best, as Goryachkina just restricts her own bishop further.} (24... Bf6 $1 {Was definitely better. Black has nothing to worry about, since White's attack leads nowhere.} 25. Qh7 (25. Rc7 $4 {would lose:} Rd1+ 26. Kg2 Qf1+ 27. Kf3 Qh1+ 28. Kf4 Bg5+ 29. Ke5 f6+ 30. Kf5 g6+) 25...

Bd6 {The bishop should be activated.} 26. Rd1 Qc8 27. h4 Re8 {Was better, slowly rearranging Black's pieces to better positions.}) 26. Rxc8+ Qxc8 27. Qd5 {Black's position, while probably objectively fine, is definitely harder to play. White's pieces are almost ideally placed while Black's still quite passive.} Ke8 28. h4 $1 {Slowly improving and looking to fix Black's pawns on dark squares.} Qd7 29. Qg8+ {Obviously White doesn't want to exchange queens} Bf8 30. Qc4 h5 {While this stops h5, the pawn ends up being a weakness} 31. Kh2 $1 {Avoiding checks on the long diagonal.} Be7 32. b3 Kf8 33. Qc2 Bd6 34. Qe4 Bc5 $6 {With low time, Goryachkina errs. I think that it would be easier to defend with the bishops on the board, since the pawn on c5 becomes a weakness. Now the position becomes even trickier, since Goryachkina has a good few weaknesses (c5, h5, eventually a7) that Ju can target.} (34... Qe7 {The bishop endgame is fine for Black.} 35. Qh7 Qe6 {Black can create some complications.} 36. Qxh5 Qxb3 37. Qg4 Qd5 {Threatening the exchange of bishops, after which I would actually prefer Black in the queen endgame.}) 35. Bxc5+ bxc5 36. a5 Qe7 37. Qa8+ Kf7 38. a6 {The advance of the a-pawn was crucial, and now the winning plan is clear. White wants to gradually bring her king in, and at the right time, will exchange queens with Qb7. Black needs to play precisely to avoid the losing king and pawn endgame.} g6 39. Qd5+ Kg7 40. Qb7 Kf8 $6 { Not the right idea, conceptually. Black needs to play actively, otherwise White can just execute her plan with the winning king and pawn endgame. A possible variation was given by Dejan Bojkov:} ({"Black's only chances for survival was connected with the active play. Therefore:} 40... Kf7 $1 {should have been played. Then the plan that Ju used later in the game:} 41. Kg2 { Can be met with:} f5 $1 42. Kf3 Kf6 43. Qxe7+ (43. Kf4 Qe5+ 44. Kf3 Qe7 { only repeats moves.}) 43... Kxe7 44.

Qd8 {Was also possible, and the a-pawn is untouchable. Black just needs to avoid the queen trade when White's king is on f3.} 46. Qxa7 Qd5+ 47. Ke2 Qe4+ $11) (45... g5 {The main defensive idea in the position. After this, Black is completely fine.} 46. hxg5 fxg5 47. Qxe7+ (47. Kg2 Kf7 48. Qf3+ Kg6 49. Qb7 Qf7) 47... Kxe7 48. Ke3 Ke6 49.

Kf3 {Black is nearly in zugswang. She wants the queen to be kept on the d-file for Qd5+ if White takes on a7, but there are no good squares.} (50. Qxa7 Qd4+ 51. Kf3 Qd5+ 52. Ke2 Qe4+) 50... Qe7 $2 (50... Qd6 $2 51. Qa8+ {And Black loses the pawn with check.}) (50... Qd3+ $2 51. Kg2 {The queen can't protect the a7 pawn and there are no more checks.}) (50... g5 $2 51. hxg5 fxg5 52.
