I thought you played the hand well. Smooth calling the flop with the intention of raising the turn looks like a good idea since it is obvious the BB will bet the turn no matter what card hits. On the turn, I think you must call the CO's 3 bet since if he has some kind of weird 2 pair you have up 8 outs to beat him. On the river, I think you should make a crying call here in this big pot. For all you know the CO may be thinking that you were raising the turn with not much of a hand becuz the maniac BB bet. Plus youve seen the CO overplay hands in the past. So calling the river looks right. Overall, I thought you played the hand well on every street.
