16. e5. 16. exd5 Be2 17. Qf5 g6 18. d6! gxf5 19. dxc7 Bxf1 20. Kxf1 Bxc7 21. Nxf5 gives White a more promising version of the Exchange sacrifice which follows at move 18.
16. ... f6! 17. exf6 Nxf6 18. Bxf6 Be2 19. Qf5 Bxf1 20. Be5 Qe7. Black could also give back the Exchange with 20. ... Rxe5 21. dxe5 Be2, but she feels confident enough to go through the storm and come out alive.


21. Qg4?! 21. Bg3 Rf8 22. Bxd5+ Kh8 23. Qh5 Qe8 24. Qxe8 Rfxe8 25. Bxc6 bxc6 26. Kxf1 leaves White with enough compensation for the Exchange, but 侯逸凡 (Hóu Yìfán), trusting in her tactical ability, aims for more than a honourable armistice. Hence, Better the worst of unbalance than the best of equilibrium.
21. ... Bd3 22. Rd1


22. ... Be2! 23. f3!? Psychologically tricky. If now 23. ... Bxd1 there would follow 24. Nf5 Qf8 25. Bxg7 Qxf5 26. Qxf5 Kxg7 27. Qg5+ with a likely draw.
23. ... Rf8. Black is too happy with a draw against her mythical adversary to dare to believe in the win. Here, for instance, 23. ... Qf8! 24. R~ Rxe5! was well worth considering.
24. Rc1!? Still tricking.
24. ... Bd3. Black avoids the trap: 24. ... Bd2? 25. Bxd5+! cxd5?? (25. ... Kh8 is preferable, even though it leaves White with all her initiative after 26. Be4) 26. Rc7 winning easily. But once again, with the glass half full in mind, Black gives her illustrious adversary an exit. 24. ... Bd8! is now very strong, intending ... Qe7-g5.
25. Rd1 Be2 26. Rc1 Bd3 27. Rd1 Be2 28. Rc1 ½ : ½.

In general, among non-physical pastimes, the longer one sits, the more one needs to think far away. Photo: 我要有耐心 (I have to be patient).
