Early against unknown.

I'm getting perfect odds to call with my oesd, but the board is monochrome.

When I hit my hand at the turn, should I raise any bigger or is this size ok ?

And what's my plan for the river if a heart his and he donks into me, how much would you still call with the straight ?

As played, what about my river sizing ? I put him mostly on a missed flush-draw, so I didn't want to make it too big to encourage hero calls.

Wp except bet bigger on the river. With his whiffed draws he won't call a river bet anyway. And with the 9 pairing on the river he is probably never folding a k or 9 to a healthy bet and isn't going to call with much else no matter what size IMO. I'm betting 350-420 here.

Oh and if river is a heart and he donks it's a pretty easy fold(unless its another gay bet of 40 or somethin)

Good point, I really lost a lot of value here by not betting bigger.
