Hi guys! Had spot in live poker that i'll like to share.

Blinds 30/60 live 8 handed

I open mp3 $150 with A5hh and HJ calls (unknown french guy that plays weird,not much sample vs him).
Hu pot flop is 55J rainbow. i cbet $220 he calls.
Turn is 7 h and i have hearts covered for the flush draw OTT. i bet $520 he calls.
River is a Ks i bet $13500 and he makes it $4500.

JK probably is the best bluff catcher we have here but is A5 too strong to fold? Without reads we basically fold non nuts here?
thoughts pls
