Rad8. If, instead, 21. ... Rfd8 there might follow 22. Ne5 (Δ Ne5-g4) 22. ... Rd5 23. Nf6+! (23. Ng4? Rxg5!∓) 23. ... gxf6 24. Qxh6 Rxd3 25. gxf6 Rxd1+ 26. Kg2 Qf8 27. Qh5 with an inevitable draw by perpetual check.
Now Gunina unleashes a pair of sacrifices which gain the Queen at the cost of too much material (two Rooks and Bishop), but stripping the Black King just enough to hope for a draw.

28. ... Rfd8? Returning the favour. After 28. ... f6! 29. Qe4 Kf7 30. Qh7+ Ke8 Black should consolidate her material advantage.
29. e4 R5d7 30. Ne5 Nc6! 31. Ng4?! Objectively speaking, White should content herself to strive for a draw or something with 31. Nxd7 Rxd7 32. Qg5+, but, given the time control, her tactical gamble not only makes sense, but it also proves to be a winning strategy.
31. ... Rd2?! 侯逸凡 (Hóu Yìfán), too, believes in the triumph of her attack. However, it is important to note that 31. ... Kf8! at once would have deprived White of most, if not all, of her attacking possibilities.

32. Qf6? Most dramatically, it is a misstep that could cost Gunina dear. The right move was 32. Qh6! (Δ Ng4-f6#) 32. ... f6! 33. e5! fxe5 34. Qxe6+ drawing by perpetual check.
32. ... Kf8! 侯逸凡 (Hóu Yìfán) seizes the day! Now White is dead lost.

33. ... Rxf2+?? But Black, apparently oblivious of a trivial tactic, throws it all away! Instead, after 33. ... Re2! White could well resign, for she is absolutely helpless against the double threat of ... Bb6xf2 and ... Rd8-d2.
