So laggy CO open and I 3bet from BB. Flop we hit set and block A3 straight. Bit earlier I had also 3bet same villain and made 1/3 pot cbet on very similar flop and got fold. This time he calls. I think he can be calling small bet with lot of one pair or gutshot or maybe even just overpair.

Turn is really not nice one as now 86 also have straight. Turn is clear check as my range is not that happy most of time here. With set though this is definitely on top part. CO bets on big side so this feels like straight or air. I think villain might bet some 75 type but probably smaller. Though I dont have reads about that.

River is blank and I check as I would do with my whole range. Probably have to fold river without specific reads if he bets? I only block A3 so doesnt feel great bluff catcher.
