Never folding. Potential for re-bluff's and thin value with lower flushes or possibly 97s. Most importantly, if he's good why wouldn't he just x/r the turn with AsXs, you probably have a fairly wide bet/folding range especially given the history that has lead you to the read that he has folded there lots in the past.
We lose to 97s(straightflush)
Interesting idea about him x/r with Asxs on turn. tbh I've never needed to be concerned with this dynamic; why wouldn't he just x/r flop?
