The main villian in this hand has been somewhat active and his stack has been on a bit of swing, both ways. He's pushed me off of one pot with position and I think it may have been a bluff.

I pick up an OESD and flush draw on the turn and I'm first to act. The pot is less than what I have left so there's a possibility of fold equity, although he did raise on the flop, so he has something. Thoughts?

What limps here UTG from a fairly active opponent? Overpairs, TT, 99, and 55 are all betting preflop, and it doesn't make sense that he would limp with T9, T5, or 95. What's his range?

5-5 is definitely in his range, as well as 10-9s is he's been active. I'd add in 10-broadway to this range too... a lot of times, bc loose opponents love these and love TP/BK

The 7 does help your hand, but the card doesn't make a whole lot of sense to induce a fold. I'd say a majority of the time you have 18 outs and a decent portion the full 21.

every set is in his limping range here. I don't like the push because I put him on a set here most of the time and you're not folding it. On the other hand, Villian has to overpush here to really price you out here. I think you're better off c/cing and folding when you don't hit and pushing when you do. You lose less when you miss and make the same when you get there.
