Savy - I agree, if J7s here is representative of the cutoff hand, where all better hands are being played, then yes he'll clearly be too wide MP. Presumably this is a spot that many of us have where once in a while we'll have a one off hand that deviates from the norm and we'll decide to open QJo UTG or something, but generally fold.

OngBonga - I just think if you don't put him on an ace, he's now giving you an excellent price on your draw. There was no clear draw on the flop, so if he's legitimately weak you will very often face a river check on this board and can steal it then. Raising the turn and facing a jam by Ax is a disaster.

What hands does raising the turn fold, that we are worried will otherwise be in a spot to win the hand if we just call?
