You were winning. You had a chance again, didn't you win this game at final endgame?
where the hell did i go wrong this game?
no... he knew how to draw... i lost mood after qc3.. he missed a fork and i was too intrested in analyzing it that i left this one slip :(
Just general good technique moves like 29.g4 32.Rxd7 or 36.Rc3 would have been fine.
In blitz games I tell myself infiltration (with threats) is worth about a pawn (if I'm too lazy to calculate). So in particular your move 36 seemed lazy.
A move the computer hates but I would have considered is 26.c5 to make the knight eternal and just generally take away pawn breaks so the black rooks will be less valuable and then you can torture black as long as necessary to win.
In short, an easy way to win is to eliminate counter play.

i thought i was about to win but he somehow swindled a draw like a magician...where did i go wrong? i know i should not rush in simplification damm
