Anyone know theory on this opening? Before the game I was aware of the position after 9. f4 and thought it was just winning, but 9...d5 resulted in a complicated position that I thought was unclear.

Does anyone have any familiarity with this opening? Black obviously made several inaccuracies but even with improvements is this h6, g5 line playable? Any insight would be greatly appreciated

Against 10. fxg5 black can play Nxe4. Interestingly enough in the same tournament (but in the open section) there was a game between 2 masters with this continuation with black winning

That's true. Thanks for the comment I'll look at it more deeply when im not half asleep :)
