Negative Freeroll concept (PLO8 MTT)

[franknagaijr]

Question - on this turn, with these stack sizes, and a non-made hand, is it better to check the turn HU and see what comes on the river, folding only to a counterfeited low that does not make aces up, and calling any other all-in bet assuming 2nd nut low should be good? Based on the stack size, I don't think there's any fold equity on the turn, but what cards could we possibly fold to on the river?

Edit: MTT new table, no info on villain other than stack size
