Bet turn, if button is TAG he probably wont overcall w mid or bottompair wich means he has Ax or set given the 2pair set is not likely. He probably would rr AQ and AK prf so ure A is good Fish probably has a 9 or gutshot either way no value in betting river since tag wont call w worse and fish probably have u beat. Id probably checkfold v CO checkcall v button.
