King’s Indian Defence E76
The jokes of fate can be cruel. Due to a curious coincidence, 于 (Yú) has both her closest rivals, Krush and Thalia Cervantes Landeiro, to meet in the last two rounds! This means, as arbiter Chris Bird says, that “even if 于润荷 (Jennifer Yú) beats Irina Krush in rd 12 [today], it still might not guarantee her the 2022 U.S. Women’s Championship as she has to play Thalia Cervantes, who is on a 4 game winning streak, in the last round!”.
Whether one believes in divination or not, it’s just the case to say that Cervantes Landeiro won today as well, thus raising to 5 the number of her winning streak.

18. Nd5? An error of bad judgment, dropping a Pawn for no good reason. 18. f5! was almost an imperative.

21. ... Rxf4?! Black should have taken on b2 at once. The interpolation of the moves that follow only helps White to give a sense to her opening flop.

Black has won a Pawn after all, but under less favourable circumstances, as now White can claim some compensation.
26. h4! Bd4 27. Kg2 Qe7 28. Rf1 Qd7 29. Bxe5 Re8? A wrong finesse which could cost Krush the game. Simply 29. ... Bxe5 would have kept the situation under control.

30. Qf3! Bxe5 31. Ba4?? A true pseudo-deflecting hallucination, which instead costs 于 (Yú) the point. The presence of Bishops of opposite colour just suggests that 31. h5!→ would have given White a virtually irresistible attack.
31. ... Qxa4 32. Qf7+ Kh8. Is it really possible that 于 (Yú) didn’t notice that the Black Rook is still defended? Yes. Apparently. Or maybe no.
