I have a question for you engine users out there
What struck you as odd in that game? And I’m looking for the things that you consider the most suspicious.
a4 on move 9
That lets me set up a nice cosy place for my bishop. You’ll notice it’s basically an outpost.
also g4 g5 is not a human idea
That is a very human idea. There is a strong riposte if the opponent captures, which is why the opponent did not immediately do so.

the bishop can't even go there and if it did the rook would take the pawn

it does not it just gives you a active position the kingside is still safe
