39. Qg3? 侯逸凡 (Hóu Yìfán) has kept up the pressure until her opponent — who was terribly short of time — slipped fatally. 39. Qg4 was called for.
39. ... Rd4! 40. Re1 Rb4 41. f5 Qxf5 42. Ne8 Bc3! 43. Qb8 Kh7 44. Nd6


44. ... Qd7. Black played the text move very quickly, apparently oblivious to the fact that 44. ... Rb1! 45. Nxf5 (or 45. Rxb1 Qxb1+ 46. Kh2 Be5+ 47. g3 Qc2+−+) 45. ... Rxe1+ 46. Kh2 Be5+ 47. Qxe5 Rxe5 48. Nd6 Re7 would have won much more rapidly.
45. Rc1 Rxb6 46. Nxf7 Qe7. The silly 46. ... Rb3?? would be refuted by 47. Rxc3! turning the tables.
