NL200 DEEP 2 pair

[The Grumbler]

Villain will gamble a little, but not too loose. I've not been at the table long enough for reliable stats. Doubled up first hand when UTG (not current villain) limped w/AA and I checked 66, flopped a set.

I've been playing alot IP and stabbing at pots, so flop CR would be standard for villain with decent hand; overpair, set, flush draw but prob not AT.

<font color="#CC3333">UTG raises to $8</font>, <font color="#666666">1 fold</font>, Hero calls $8, SB calls $7, <font color="#666666">1 fold</font>.

SB checks, UTG checks, <font color="#CC3333">Hero bets $18</font>, SB folds, <font color="#CC3333">UTG raises to $36</font>, Hero ???

My instinct was to 3bet, but not sure how much, or if that's right this deep. Does it turn my hand into a bluff??
