Best line here?
Check-call, and reevaluate on the turn. Many players will automatically Cbet that flop, but the villain will almost never fold here.
Depending on the villain's profile, check-call or bet-bet. Without history I would check here.
Don't cbet the flop, the villains range includes medium pairs and 2 high cards. The flop isn't scary, and quite good for the villain's range. Check-call.
I actually check-called the flop, hit the Q on the turn and won the hand, check-calling the river. Villain sowed 77.
