only hands we beat are 8765 and naked aces. This is very read dependant but i lean towards folding. even if it is a bluff , it is a good bluff.

Fold! Good chance the button open with 3 high card with suited Ace. Might fluke it on the river with A3! I would not check the turn, If you decide to bet the flop continue betting. Or check-raising the flop is a good option. If he called out check-raise, we are done with it. With bottom 2 pair, I would like to take down on the flop esp OOP.
