So here we are pretty much read less in the BB

Let's say for example that UTG is full stacked and CO is the fish. I always feel like maybe I should be squeezing to isolate, but usually what ends up happening is I get called in 2 spots, the reg who raised first is uncapped and the pot is massive. Also, I have less FE and PE and my hand doesn't play that well (I mean it plays ok but not great I don't think)

On the other hand, I feel like letting people in with their equity and being OOP against two players sucks a bit, and squeezing would hopefully narrow the field, increase my PE and FE postflop, but they never seem to fold much when I take that approach. I then have to be really careful about cbetting because honestly it feels like I'm lighting money on fire betting into 2 people, especially a fish, on tons of boards.

Overall, just a little confused about how to approach the situation and any help from RIO members would be greatly appreciated.

Cheers
