small flush on paired board - multiway

Pre I might bluff squeeze this but I think calling is not bad.
OTR it is pretty difficult to know what would be the best move. Villain looks like a fish. He doesn't really rep any full houses by just calling OTF and OTT but he can still have those. He can also have higher flushes and decides to shove even if the board pairs. But I think he has some Ax and other stupid hands in his range too.
I think folding is reasonable since we have to act before UTG and he can have those full houses.

SCs can be played mw so call is fine preflop.
OTR with bet and raise in front, I think folding is ok. The more people interested in the pot, the bigger the possibility of one of them crushing you.

I agree with the preflop-call since it's just a 2x-Raise.

Postflop it's fine. Multiway there's a low chance of having enough foldequity to check-raise the flop (even though it's reasonable!). But I would rather do it with a stronger flushdraw than the possibly weakest you can hold. You kept the pot small up to the river and that's fine. When the board pairs you can basically check/fold vs. a bet and a raise.

Btw: Since you already got more than the needed pot-odds on the turn, you don't even have to donk the river if you hit. But in case the flush would have hit, without a paired board, a small sizing (like 1/3 pot) would have been reasonable. Just to keep the calling range wide

Thanks guys ! shame river was not T♥:
With Q high flush I might have called

TBH I don't see any sets on the flop or on the turn playing like that, just flatting in 3 way, given this board is draw heavy, only better flushes might scare me off from calling.
