zoom AQo BBvsEP river call?

I think you shouldn't worry too much. Folding river would be too weak since then you'd probably fold close to 100%. It takes a read to do that.

KQ/QJ should not bet heavy for 3 streets.
You can find a fold here.

I agree with nitrol about that. You are not going to beat any value hand...

I'd still call all AQ, but maybe fold some of them on, say, 2♥: instead of 2♠:. The hand is simply borderline, which is why you shouldn't worry too much.

Indeed, I think I can find a fold here OTR.

We could squeeze preflop, but I call by default. Also my default postflop game would be check/call twice, so I would fold the river. I think we will too often be behind, especially vs UTG's tight range.

First time around (and second) I missed that SB was in the party OTF. This makes UTG a little bit more credible, so I lean more towards folding river. (I'd still sometimes call a good UTG that knows the basics of hand reading if I have a tight image. Our hand is face up.)
