I think I prefer folding river.
His size is like 2x the pot. You will have the Ah often enough to fold every time you don't have it and not worrying about being explored by bluffs,I think.
And I don't think he would have a lot of bluffs there. It will often be the Ah, too.

Can make a case for checking flop as I don't think you can get 3 streets on bricks and your hand isn't terribly vulnerable. Turn check is ok at some frequency. River, I like the bet but might size bigger. River facing the raise depends on how you play your range. If you have plenty of ace high flushes and this hand is at the bottom of your river value region, then you can fold. From an exploitative stand point I'm not sure (I don't play much in these games). My guess would be river raises generally don't contain enough bluffs in these games. Boats make a lot of sense here. You're going to have a better understanding of the population tendencies than I am.
