9/18 hard flop decision with JJ

[bakku]

last hand from the 9/18 Commerce
UTG+2 is laggy, like cold-cap AJo, raise QTo UTG, slows down to aggression postflop
SB is unknown
BB is loose weak preflop (limping AK 3 times so far) but seems ok postflop

I raise J [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/club.gif[/img] UTG+1, UTG+2 3-bets, LP CC, SB semi-CC, BB semi-CC, I cap, all call. (5 for 20SB)


Flop is 5 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/spade.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img]
SB bets, BB raises, getting 23:2 what's my action and plan?
