The position has an unclear character. If Black manages to stabilise and strengthen his position, he will hardly be worse. White needs to play energetically.
The decisive mistake.
Black could maintain equality in the complications after 25...gxh6! 26.Bxe4 Nd2!. There are many variations here, but there seems to be no advantage for White in any of them.

An extremely important zwischenzug, which wins for White.
It was not too late to step on a hidden mine with 27.Bg5? g6!. Here, it is Black who plays the zwischenzug, after which he is simply better.
