Hello,
Few hands ago before this one, I had a similar situation where the same villain min-raised from EP and I called from BB with the difference being that in that hand he c-bet 1/2 on all three streets, where this time he cbet only the flop which made me think that he missed and might have something like AK, AQ, AT. Having that in mind, on the river I thought that I could make him fold these with almost any bet-size as long as its not too tiny. Not sure about my call OTF though. I considered check-raising but I felt like he will only call if he has an overpair.
