3-6 Prima ... iso with A7o

[secretprankster]

A9o vs. a single limper is $$$, even with a loose BB. I'd raise A7o too but it's closer and I'm not sure I would go any lower, so that might just be an arbitrary cut-off. But as long as you're not auto-3-barreling on terrible boards with ace high, folding A9o there will definitely be suboptimal IMO.
