first move out of the Benko book, and black goes wrong.

I fully agree, b5-b4 is just wrong. But in fact already 4...g6 is
suboptimal.

yes white should attack this structure with something like Bg5 and h4 for
h5 - with fixed central pawns locked white can play as if a piece ahead.

I thought the moves e5 and h5 looked quite weird.

bit hard to follow this in my head, with long-algebraic, but what is
indicated for white is a kingside attack, pawns an pieces

Well, black is not that badly placed, because white's pieces are a bit
tangled up. Black needs to find something to do though, while white
clearly can try to untangle as in the game and is then starting to do
well. I didn't think white was quite ready to open up the game due to the
messy position of the white pieces. Of course one can also usually rely on
this program to dig its own grave if one lets it move about for long
enough in closed positions.

white does nor grasp the need to get after black's k side and spends 6
moves going sideways to no advantage. 6 moves = 2 pawns!

Actually, when I was playing the moves I thought that it's here that I
started to have a clear advantage on the queenside. In contrast the next
moves by black, namely knight to b6 and then takes c4 and in particular
that queen sortie are completely misguided.

it the chess engine is just point-counting, the engine has no positional
sense at all.

There's no point even discussing any further, this is a point where black
is already completely lost, whether it crazily gives up the exchange in a
moment or not.

yes

Of course this move is completely weird and idiotic, but the game is lost
already.
