In the game, Black missed the win and chose the quiet developing move 16...Rad8?. White was not up to the task, and after 17.Re5? (she could have avoided loss of a piece with the only move 17.Kg1! Qg5 18.c4 Bxd5 19.cxd5 Rxd5 20.Qxa7 Rd2 21.Qe3 Qd5 22.Qe4=) 17...Rxd5 18.Qxd5 Bxd5 19.Rxe7 Bxh1 20.c4 Bc6, lost anyway.

White had been counting on exploiting the tactical motif of the X-ray of the Rb1 on the black queen. However, he failed to appreciate the vulnerability of the f2-square, a pawn defended only by the king.
Black wins equally attractively after 21.Rxe7 Rxe7 22.Ba3 c3!! (22...Re5 23.Rxb6 Rxb6 24.Qa1 still allows White to resist) 23.Rxb6 cxd2 24.Rxa6 Rc1 25.Bf3 Rxd1+ 26.Bxd1 Re1+ 27.Kg2 g6 – the passed pawn brings Black victory.
The sacrifice of a bishop on this square is a typical idea, but it is rare to get a chance of doing so with the queen. The white king is forced to undertake a journey across the board, which will end in his death.
