A novelty of very dubious merit. Hence, Black ought to play 11. ... f5 12. exf5 gxf5 13. Qg5 f4 14. Nd5 e5 15. Qxd8 Rxd8 16. Nh4 Nd4 with an approximately balanced game, Khodashenas – Firouzja, 52nd Iranian Chess Championship, Jam 2019. 12. b3 Qa5 13. Bb2 Qc5?! A little better may be 13. ... Qh5 eventually followed by ... f7-f5. 14. Qd2 Ned4 15. Nxd4 Bxd4. After 15. ... Qxd4 16. Qc1 Black’s situation is quite uncomfortable.


16. Nd5! Bxb2. Indeed, Black has little choice but to get crushed at the bottom, because 16. ... Bxf2+ 17. Kh2 would allow White too many threats. 17. Qxb2 a5 18. a3 Be6 19. b4 Qa7 20. b5 Bxd5 21. cxd5 Ne5 22. b6 Qb8 23. Rac1 Rc8. Otherwise the White Rook will penetrate to the seventh rank. 24. Qb5 g5 25. Qb2 Rc5 26. Rxc5 dxc5 27. Qd2. But why not play 27. Qc1 attacking both c5 and g5? 28. ... h6 28. h4! f6 29. hxg5 hxg5


30. d6! A very strong move, preventing Black’s Queen from moving to d6. 30. ... Qxd6?? But Black refuses to believe evidence and ends up blundering away her Queen. 30. ... exd6 was correct, after which there could follow 31. g3! Kg7 32. f4 Nf7 33. e5! with White breaking through on the open files. 31. Qa2+ Kg7 32. Rxd6 exd6 33. Qe6 1 : 0.

Thus, by defeating Assaubayeva 13½ – 9½, 侯逸凡 (Hóu Yìfán) became one of the four semifinalists of the 2nd Online Women’s Speed Chess Championship Main Event. Screenshot from the live stream.
