As a result of a forcing combination, two black bishops are under attack.

Black resigned.

The correct decision is not to drive the white king further towards the corner, but to draw him out into the centre:

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.

Driving the king into the open.

White can mate with a series of fireworks:

4...Qf3+ 5.Bxf3+ Nxf3 6.Rh1+ Nh4 7.Nf6+ Kh6 8.Rxh4+ Kg7 9.Ne8+ Rxe8 10.Rxh7+ Kf6 11.Rxf7#.

Deflecting the rook from f8.

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.
