live 100NL, 1/1/2 at LC with bottom full house

[wutevahung]

villain is UTG+1, sat down couple orbits ago, played less than 5 hands, havnt raise before the flop yet. had about $100

i was playing a pretty TAG game, had about $400

even though the game is 1/1/2, it is 4 to call

preflop:
UTG+1 (villian) raised to 16, 2 loose players with about 400 called him from MP and LP, i called with 98 clubs on sb and a tight player called on bb with about 200 in front of him.

flop:
KK9, 2 hearts

we checked around.
i was surprised but then i thought the only person who might have the king is BB because witht the flushdraw, only people in early position would try to check raise.

turn: 9, board kk99

i again checked, bb didnt look happy with the 9, villain bet 46, both of the loose players fold back to me, what should i do?

i thought that the only hand he would check on the flop is with a full house or 4 of kind, i did not give him the credit of kk or 99 because it doesnt happen that often, and AK or KQ would want to keep the flushdraws out, k9 didnt seem possible since he was UTG+1

thx

fold bottom fulls in multiway pots

[wutevahung]

i would but no one represent any strength
and villain looks like he had something like JJ and QQ wanted to steal the pot to me
