My apologies then, I misunderstood.

My main line after 28...d4 (much better than 28...dxc4 like you say) is
29.e6 Qe8 30.h6 Ng6 31.Qh5 Nce5 32.hg+ Kg7 33.Qxh6+ Kg8 34.Rxe5 Bxe5 35.Qxg6 Bg7
36.Qxf5

I do not know of a program that sees e6.

Here, check out these variations too! from 20.a3 Ba5 21.b4 Bc7 22.Bxh7+ Kxh7
23.Ng5+ Kg6 24.Qg4 f5 25.h5 Kf6!?

First I checked 26.Rxe6+ Qxe6 27.Nxe6+ Kxe6 28.cd+ Nxd5 29.Qg5 Nce7 30.Qxg7 Rh8
31.Re1+ Kd7 32.Qf7 Rcf8 33.Qe6+ Kd8 and the position is maybe equal!

But then there is 26.Nxe6+ Kf7 27.Qg5 Be5 (27...Re8 28.b5) 28.Nc5 and it's all
over.
