live 2-5NL, max value from flopped full house

[gobbluth77]

The villain in question here is a loose, semi-aggressive thinking player. I open raise to 15 in late middle position with 33, villain calls on button, big blind calls. 3KK rainbow flop, i lead out for 30, button calls, bb folds. What do I do on the turn? The only way I can get real action is if he has a king, but what if he smooth called me with a pocket pair, or is just floating w/AQ or something expecting to take it away later? If I check the turn, I think he checks behind w/a pp, and then might call a bet on the river. If I check and he was floating the flop, he obviously bets, but shuts down when I call or raise. I decided to bet 50 on a 9 turn, he thought then folded, and later said he had AQ and thought I actually did have a king. How do I extract max value here out of his hands that do not contain a king?
