With the irresistible threat of 34...Qf3.

In this case, the zwischenzug helps Black equalise.
A) 13...cxd5?! 14.Bxg7 Kxg7 15.bxc4+=
B) 13...Qd6?! 14.Bxg7 Kxg7 15.bxc4+=

Black even temporarily wins a pawn.

Draw, because the variation 19...Qxe2 20.Rxe7 Qxa2 21.Qxb7 Rab8 22.Qxa7 Qxa7 23.Rxa7 Rxb3, leads to a complete elimination of the fighting forces.

White is to move, and Black has a knight under attack.

It turns out that we can first attack the queen, creating in the process the deadly threat 18.Qxc4+. In the game, there followed 17.Qxf5 Qd5 18.Qf3 Qxf3 19.Nxf3 Bf6, with Black having sufficient compensation for the pawn. After:

Thanks to the pin on the bishop, the c4-pawn is lost as well. White is winning.

If we now simply take the bishop, then White’s advantage in the opposite-coloured bishops position will be minimal. Instead, White sees a tactical motif, connected with the unstable position of the black rook and the insufficiently protected black king on h8.

Even more precise than 25.Rxb7 g6.

Black resigned.
