{ This is a moment where Irina must have misjudged Black's threats on the
queenside and blundered with }
46. h4?? (46. Be1 { would have maintained a
small advantage. }) 46... Qa5+! 47. Kb1 Bxf5!? (47... Nc4! { was an even
more unpleasant continuation as after } 48. Bxc4 dxc4 { , ... c4-c3 is
unstoppable. } 49. Bd4 c3! 50. Bxc3 Qxc5 $19 { and with the f5-pawn falling,
Black's attack with opposite color bishops will be difficult to deal with for
White. }) 48. Qxf5 Rxb2+! { Another sacrifice that destroys White's defense. } 49. Kxb2 Rb8+ 50. Kc1 Qa3+ 51. Kd2 Qb4+ 52. Ke3 Qxc5+ 53. Kd2 Qb4+ 54. Ke3 Qc5+ { Despite spending the remaining of her time, it was difficult for Jennifer to
decide how to play on. I spent a bit of time analyzing this position and I
think it makes sense why. For the purpose of beauty I will show the engine's
line to maintain the advantage for Black. } (54... d4+!? 55. Rxd4 (55. Ke4 Re8!! 56. Bxd4 Nc4+ $19) 55... Qc3+ 56. Rd3 (56. Bd3 Qc1+ 57. Ke4 Re8! 58. Rd8+ Rxd8 59. Qxf6 Re8! $19) 56... Qc1+ 57.
