tbh not sure if a c/c or c/f is best, would have to stove some ranges.

You don't need very much equity to call this but I don't know if he's doing this often, if ever, with hands you're ahead of. I think KK, QQ check back almost always and AQ checks back some of the time.

I think I'm leaning towards a c/f given that this guy seems a bit weak/tight.
