Lost a winning position? Where to improve

This game was a block center position vs a higher rated opponent. I had a good position I think, but did't capitalize on it, any suggestions?

 

I know this Black opening, play it myself. I'm only on the app here and it's difficult for me to comment properly, but...

It was a good game, good struggle.

Your ...b6 was too slow and unnecessary IMO. You need to get off that queenside counterattack ASAP. But you did correctly sac a pawn in that queenside counterattack, excellent.

Your ...Ne8 and ...f5 I'm skeptical about. It seemed to work out ok in the game but it opens lines on your kingside, which in theory you don't want.

I think you lost the game when you abandoned your strong attack on his king for the sake of greed.

Get that king, don't be materialistic.

Best I can do inebriated on a phone.

Thanks urk, learned about this opening from a lecture by GM finegold, apparently he got it from Anand back in the day.

You were doing great. It's just 25. ... Nd3 which you have marked with a ? yourself. 

 

It loses a piece doesn't it. And that is surely game over. I was thinking you would play 25. ... Rfb8 and you are building up great pressure against the king.

Yea, its basically over after my blunder I guess. Furthermore it doesn't make sense to simplify to an endgame down a piece, still I was hoping for a draw

31. ... Nc6+ Really ... Qxa3 then white has to play Re8+ to avoid mate.
