[PLO4] Acies with blocker - call or fold river?

It's safe to say we don't have best hand pretty much ever on flop with two player interested on rainbow coordinated flop.

But we do draw to nut straight and have backdoor flush draw. Though having that as A high would be better. I would count 4 outs from straight and 1-2 from backdoor straight and top set draw. I mean if turn is A it will open nice amount of nut outs.

So some 13% equity on flop. We would need somewhat over 20% but there is lot behind so flop call is fine.

River is snap fold to me.

I would just fold OTF.
Except the 4 King Outs OTF there is no turn you like imo. Lets say 8♠: comes OTT. You check and BTN bets pot.

What do you do?

In this kind of spot aces in MW are not that good imo. If you call those hands too much this really affects your redline in a negative way.

Yeah, was thinking about folding flop, decided to call cause I hold a blocker and so the str8 is not so likely for Villain and I thought I could still have the best hand, but in PLO it´s always tricky with acies. On river it was clear that I do not have the best hand and folded of course.
