11.O-O-O, b4

I consider that long castling weakens the position of the white King, short castling was preferable; especially with the pawns on the white diagonal and I think this was the cause of White's defeat.

12.axb4,♘xb4
13.g4, ♝e7
14.g5,♘d7
15.h4,♘c5
16.♚b1, ♖b8


17.h5, OO


18.g6, ♝f6

Here White has several attack alternatives, but all should be focused on attacking the Black King for example 19. gxf7 +, or 19.gxh7 +, or 19.h6

19.♖dg1, ♝a8
20.♝g5,♝e5

I do not understand White's strategy, because if they played 19.♖dg1, then why do they play 20.♝g5? if this play obstructs the action of the tower in g1

21.gxh7+,♚xh7
