Hi.
I am really really sorry for a crappy hand history, can't find those hands on my computer...
BB - huge fish, ~medium stack
F (BTN) - unknown reg looking guy, we are ~110 bb deep

I was playing little like a scared money (took a shot lol) so couldn't decide bet or check turn.
Now I think I should bet - most of the times btn will have gutshots+fd's QK, QT, KT hands.
Board: J♥Q♥8♥ 3♠

What should be my river play if we bet and he calls turn and river is not a heart? I think his range will be mostly Qx, so should I shove or bet less to induce a crying call?
As played, when I call turn and river gives me a flush - maybe I should donk bet smaller? When I donk shove my hand is pretty much face up
