Fold the flop or three bet it. I definately fold, but given your reads maybe you 3 bet. If he peels but calls the turn we're probably in trouble. If the plan is bet/fold the river, which it should be based on the way you played it, a check fold on the river after 3 betting the flop is not outlandish and saves us a big bet. I don't think this hand is strong enough to want a showdown if UTG + 1 gets past the turn. If we 3 bet and are dealing with AK we no longer have to worry about the BB drawing to whatever outs he has. How many players can successfully bluff AK on this river after a flop that was 3 bet? Probably not many. Bottom line - I want BB off his hand if I continue past the flop. I also wouldn't hate a bet / fold on the river if you're suspicious of AK, but only after a flop that was 3 bet. If BB calls a 3 bet a check fold is easy on the turn and we save money.
