i would have raised the flop i think and avoided the situation altogether, you might have gotten an A-Q or something from UTG out of the way
but as played, i make the raise on the turn, UTG probably has A-Q or a hand like Q-Q or J-J, and the button could have a similar hand...by raising there's a small chance you just win it right here, and even though most of the time you won't you have a ton of outs to beat/bluff either or both opponents...i think this spot is tailor made for a semi-bluff
Raising the flop does not accomplish anything for my hand. I basically have to carry out an expensive semi bluff to show profit. With a drawing hand, you usually want as many players in the pot as possible, so c/c the flop multiway to induce a call from the 3rd player is clearly the best play imo.
The turn makes the hand interesting, since now I actually have a made hand as well. If I had not caught the 6 on the turn, I would definitely c/c again, because now I really need both players to fold a good % of the time for a turn raise to be correct. But since I paired up, I have some showdown value and will still be able to win the pot w/o having to hit my flush. This is'nt quite a semi bluff turn raise, more of a protecting my hand raise.
