JJ fold

[crunchy1]

I just don't understand the PF cap. UTG seems to be a tight player and most likely is 3-betting with AA-QQ and AK. MP1 is loose but aggressive PF and here makes a very unusual call of 3-cold (AA-22???, Ax?). I can understand capping it if you're putting UTG on AK and MP1 on a smaller pair. If you're going to make this read and cap PF then don't you need to see this hand at least a round further on this board? Wouldn't you cap the flop to drive out UTG... bet the turn and fold to a raise?
