Villian is 50/12 over about 20 hands, no strong reads.

How do you like the turn check?

How much do you bet on the river?

i dont like turn check given villian, bet at least 15 on river

Turn check is kinda meh... I don't hate it though, I think it has its merits.

Gotta lead out on the river for 10 or more... it will be a tough spot if he re-raises. If he pushes I think you should fold, but call down something reasonable.
