Well I would think JJ would bet out or raise on the flop. TT is a possiblity but I would expect some sort of raise pre-flop at the least. 44 I think is unlikely since there are two 4's on the board. 22 is a possibility. I think any T or two pair though would be a strong canidate too. I would think that a hand raised on the river would be pot-committed enough to make the call with a weaker hand than kings up.

good analysis?
