@shallow-bluesaid @greenpawn34 Interesting - the Tarrasch seems to have become a fashion at my club as well, but nothing as aggressive as this!
The game actually transposed into a Queen's Gambit Accepted, where White's h3... wasn't terribly useful (as Geoff remarked). I used to play the QGA and liked it, but it's sharp and Black had better know what (s)he's doing.
Yeah, a QGA I was looking at it possibly being a Tarrasch from White's side which is
the only reason I could figure why play 4.h3 if not to transpose to Black defence as White with g4 covered. Strange play indeed.
I cannot really blame 4.h3 for the loss - White is allowed to lose a tempo in the
opening and playing White as Black reversed is a bit of a trend. I used to do it myself.

Yes - I've noticed that all kinds of variants of the QG are quite willing to morph into one another, or into the Grünfeld or Catalan or several others. I have to tell you, it makes writing the weekly club report a fraught exercise for a wood-pusher like me. At least with the Morra, I know where I stand.
If in doubt - leave it out, though miscalling an opening is not too important.
My comments are my first thoughts and I note up the game as it happens.
When Nepo played c5 I was thinking this could go into a reversed Tarrasch
and h3 might be very handy. (or not) easy enough for me to edit the line but
that would be like taking a move back. I only edited for spelling or if I missed
out a word. If I drop a real clanger and way off course I'll admit it.
