JJ: I feel lost

[bruin]

No reads on opponents. .5/1 full ring at pokerroom.

UTG limps, everyone folds to me on button, I raise with black JJ. SB folds. BB 3-bets, UTG cold calls, I make it four, they call (BB calls instantly if this is a tell)

Flop comes KK7 rainbow.
BB leads, UTG folds, I call (?)

Turn comes 8 [img]/images/graemlins/diamond.gif[/img], putting 2 diamonds out there.
BB bets again, I fold.

Comments???
