Draw or loss.

I went for a draw in this endgame because I was outnumbered with pawns. I chose to go for the draw than the loss.

bad decision in my opinion, after 36.Qxf6 Qxf6 37.Bxf6 gxh3 38.Kxh3 you should win easily, and if black doesn't exchange queens with 36...Qxf6 then his king is too weak, also you had 15 minutes in the clock, so you should have seen 36.Qxf6 there is literally no reason to take a decision like that when you have 15 minutes to think.

Was it rated or casual? If it was rated then going for a guaranteed draw probably was smart, but if it was casual you should have gone for a win.

@vinciho It was rated.

Earlier you had 29 Qe7 (with Qf6 to follow). But even better was 29 Rb7, winning the queen.
