KK in LP, everyone is playing

[brettbrettr]

10/20 live game, good game. You've got some not good table coaches instructung the slightly better but trickier players how to play. Some tight passsives, some loose players, and yours truly.

I have 2 black kings in LMP. 3 players limp, I raise, blinds call.

Flop 663, rainbow. (12 sbs)

Checked to me, I bet, both blinds call utg folds, utg +1 calls.

Turn 8: (8bbs)

UTG +1 bets. Plan?

Utg+1 is a one of these chart players who tends to suck postflop. He knows which hands are playable, but doesn't consider the situation. EG, he'd open limp in LMP with 98s because it is "a limping hand." That sort of [censored].

The blinds are typical. They don't fold pairs, they're loose, they suck, etc.
