I think he should be betting most of his Ax OTT given how many draws there are but I feel like a whole lot of players at these stakes like to delay their 1-street of value till the river with pretty strong holdings actually. His sizing also looks a bit scary and he probably have very few hands in his range that didn't make any pair or strong enough draw to bet on earlier streets. OTOH it looks polarizing enough to where I wouldn't expect him to vbet KQ anymore.
I tend to think this is still a reasonably easy fold but I wonder if we should call this in theory vs a really good opponent?!

Plot twist: He has been from Sweden, so autocall right? :D
