First Hand
Not a fan of the turn bet, I would much rather check/call here for the chance to have it checked through. We arent ahead here enough times for betting here to be profitable, fold equity is almost nil against players with those stats plus facing a check raise here against a monkey would be extremely painful. Depending on his showdown standard I am check/calling or check/folding the river UI. Most of the time given those stats I am check/calling the river.

Second Hand
OOP with 3 to a flush with a suit we dont hold as well as the straight possibilites I think you can feel relatively safe folding to his bet.
