Bet size advice please

Prop60

My exit hand from a heads-up tourney from earlier.

Ok, so a cooler on the river but I wonder if I should be betting bigger after the flop. Did I price him in?

Fold pre.

pre is pretty bad - you should always fold there, even more so with your stack

I don't mind getting it in but the mistake is pre
