Hero in the BB w/ Ad8dQhTh. UTG raises to 17.5, every one calls to me. Due to the short stack nature of the UTG raiser, I opt to flat here out of the BB. My thinking is that there are few scenarios where a raise doesn't still result in a 3 or 4-way flop. Open to hearing thoughts otherwise...

Flop: 3h6h7h

SB checks. I check. I can't see a bet here ever being profitable. UTG bets 3/4 pot (43.75), CO folds, BTN calls, SB folds. I would fold against several players I have notes on, who either would never bet this spot without nut flush or players who'd put enough pressure on me that I'd have to fold on later streets. Here, this table had been passive enough with both UTG and BTN being unknown to me except for the 20 minutes at this table. I call. Thoughts? I probably fold J Hi flushes in this spot.

Turn: 7d
Bad card for me and likely UTG too. Probably good card for BTN. It checks through.

River: 6d
My main question for this post: Is betting this river great thin value, or a great way to value own myself?

I chose to bet 155, enough to cover UTG. It's such a binary situation in my mind, especially since the 6d knocks out a ton of possible FHs.

Against some players, I'm getting better flushes and weak full houses to fold and against other players they are calling with those and worst flushes as well as the occasional A7. I can't really tell if I'm making or losing money in these spots.
