I spent a lot of time trying to figure out the puzzle with no success. It's amazing you found it in such a short time.

Well, the bltz game I played gave me only the inspiration to create the chess puzzle, which I posted here.
(In the blitz game I actually saw the decisive attack already when I played the prepairing move h5!)

In the past, when I was still more active on HIVE, I have composed many chess riddles which is why the number of this chess problem is that high (82).

Finally got it after using the other games as reference and knowing h3 as the crucial square.

Later I will post a complete solution. There are quite some interesting side variations (check for example moves like Rxh5 or Rd5).
