White P@e5? played here. There was no need to be afraid of the sacrifice on h2 (Bxh2). Two ways are possible at this time. P@e6 with pressure on f7. Or P@f5 with interrupting the cover of the pawn e4. Pawn e4 creates pressure on square f3, on the white castle position.
Here, white on board A steps back and plays Nh3?. It is a too passive. The correct was P@f6 with the idea N@g7+ and Bh6 with pressure.
The game continued with a few moves.
Here, white plays N@d5?!, it's not a complete mistake, but e6 with pressure on f7 is faster and more direct.
Here, white on board A dropped P@e6?, he still had to play e6. Bad was wasting pawn, because every pawn will be important for next attack.
Here, white dropped N@d5?? on board A. He should played exf7 and after Rxf7 coming e6 with pressing to f7. For example: e6 Rf8 B@f7+ (or Rf8 N@f7 threaten to have a heavy attack on h8 or N@h6) Kh8 P@h6.After exf7 Kh8 follow P@h6 with unpleasant pressure on g7. Now black is in danger of an unpleasant attack via N@h5+.
