The consecutive Nh7 and Na7 moves look very odd. (N-KR2 and then N-QR2 in English Descriptive)

There are any number of ways of playing the opening in these nebulous variations. I would adopt a premise as Black to decide to play an .. e5 based structure or a .. c5 based structure and fit the rest of the play around it. After that you may need to look carefully at the tactics. White's idea of Rb5 and then swinging it across to the King-side looked very string.

My instincts are telling me that 23...Qxg4+ is what you want to play, and the calculation supports that: 24.Kf2 Qh4+ picks up the rook, so white has to play 24.Kf1, to which you can reply 24...Qh3+, allowing you to play ...Bxc3 having picked a pawn up in the process.

I didn't expect her to recapture with the queen

What else is she going to do? 23.Nxd2 Qc5+ loses instantly.

Your attack might have progressed significantly more slowly had he played 12...h5.

Sometimes these exchange-up positions take some time to win, especially when the opponent has a strong passed pawn.

Bogo's .. g6 reply seems very logical. Most players would accept the Fischer verdict and play cxd4 .
Why logical?

Black plays .. g6 to keep the Knight out of f5. Later you might relocate the e7 Bishop to g7 either via f8 or f6. Also you have the opportunity to gain a tempo with .. c5.

I mean I got an advantage but it was lost until 25.Bxe5 was found

I'm sure we've said this before, but go through the game with an engine and pinpoint the moment your advantage dissipates, or you didn't play the most promising continuation. 21. g4 seems to retain rather more initiative than 21. Bh5 . Once you hide in the corner with 22. Qh2 instead of 22. Qxf6, Black must have chances to outplay you. Grovel moves like 24. Ndb1 don't improve matters, particularly when you can still hit him with g4.
