can this position be won by White if he is to move?
It looks sufficiently complicated that a White win should be possible, whether it's forced against best play is entirely another matter. I'd start with Ne5, but you would also attempt to analyse Kxe4 and Ng5+. Looking for moves that are a threat, check or capture brings up Nh8, but that could be met by .. Rg8.

13...Bh6 looks horrible. What on earth is the point?

Threat of Bxf4 perhaps, but it just provokes Nc4.

More generally, playing Modern Benoni positions passively, particularly against four pawn attack/Taimanov structures (d5,e4,f4) invariably ends up with Black getting blown away with e4-e5 as seen in the game. So it's not one individual move, the whole structure of Black's defence needs review.

[

I'm not convinced by .. b6 and .. Ra7. Challenging for the e5 square with .. Nbd7 and .. Re8 looks more normal. Spassky and others of his era would continue the attack for White after playing f4 with e5 anyway and meet .. d6xe5 with f5, freeing the e4 square for a Knight.

I guess I wanted to prevent f4-f5, by exchanging the dark-squared Bishops in case of f5.

You really need to learn something about Benoni structures if you're going to play them. White's thematic advance is usually e5, not f5, and the g7 bishop is the one minor piece you really don't want to exchange off.

How to learn about it?
I know you are a benoni specialist

Most of what I know about the Benoni I learned from John Nunn's book. It's a bit out of date now, but most of the strategic advice still holds.
