Table is loose passive and generally gives me an erection.

Hero has JJ in CO. Couple limpers, Hero RAISES, everyone calls.

Flop (12 SB): Q 5 2 rainbow (6 players)

Checks to me, Hero BETS, everyone calls.

Turn (9 BB): 3 (6 players)

Checks to me, Hero BETS, 1 fold, everyone else calls.

River (13 BB): K (5 players)

Checks to me, Hero...? (Button remains to act behind us)


Value bet? Why or why not? If so, what's your plan if Button raises? if someone check/raises?
