I check the flop for 2 reasons. Villian is insanely weak tight, he folds everything to this flop bet so I don't feel there is any value in it. The second reason is the pot is a good size already so I can bet the turn and river to get all the money in(55 into 75 pot, 125 into 185). I feel that the turn is a call, as AK is obv the only hand that beats me and no one ever has quads. But then again this type of player isn't who I would credit with doing a 1.5 buy-in bluff. Any other opinions?
