In the game, there occurred 28...Rxc4 29.bxc4 Bh4 30.Kf2 Qxc4 (on 30...Rg5, there follows 31.f4 – this is where we see the excellent position of the queen at e3!) 31.Qd4 Qxc2+ 32.Rd2 Qc5 – the endgame looks equal and ended in a draw.

Black wins easily after 29.Qe2 Rxc4 30.bxc4 Bh4 31.Kf2 Rg5 – there is not the move f3-f4, and the Ng3 is simply lost.

Taking with the king allows the black queen to be included in the attack with tempo: 31.Kxd1 Qd8+ 32.Ke1 Qd4 33.Rg2 Bf4 34.Nf1 Rh1 – Black completely dominates, and has the irresistible threat of 35...Kf8, followed by 36...Bh3.

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.
