What about the other streets? I bet the flop since I knew I would get at least 3 callers. Turn, no point betting. River, do we have a call? So far I haven't seen MP make any aggressive moves at all really. Not that I can recall anyway. Button only calling this river bet suggest that he has no better than Tx.
