easy fold

I think you played it fine. Just fold now..

What do you think about making a $20 blocking bet on the river to avoid being a huge bluff by a missde flush/straight draw?

[the machine]

cant make a blocking bet here. preflop it is very likely for CO to limp with ax 8 and under suited in heart and call every bet on every street 3 to 1 on the flop 3.5 to 1 on the turn. and at this limit hes not letting go of the ace he just hit. your bet if he does have a8 and under is going to be called by him no matter what if thats what he has so its a profitless bet imo. check fold is the best option here unless you have a great read on villian then i still only check call a small bet, def not pot sized bet

Theres a good posibility hes actually missed a draw and tries to buy it since no one claimed it on river. I'd call.
