Big Blind was the maniac guy, and he bet out into every street into the pre-flop UTG raiser right?The way that the UTG raiser kept calling down the bets by the BB the entire time without a raise after rasing pre-flop, and knowing the BB could literally hold anything, I am guessing the UTG player held AK and called him down. The way you had it worded though I wouldnt be surprised if the UTG player had AA or JJ and just called it down for some moronic reason. My guess on the BB is absolutely nothing like 7-4. I think he would have pressed more if he caught any piece of it on the end.
