villain hasnt beeh out of line. Hes won a few med pots but hasnt shown a hand down yet.

im confused on whether c-betting or checking behind is best here. C-betting seems best in my mind because villain can bet the turn and i have to fold if i dont hit. And im not that thrilled about calling a turn bet if an A hits.
