AJo on J42cc 

New to rush, havent played many hands so not much info on villain, although have him marked a reg. Obv otf out hand is really nice, with Ac blocker i feel like calling down > raising getting it in. However on this riv i was leaning towards a hero fold? What would you think about his sizing on the riv? Seemed in game like QQ or KK goin for thin value, thoughts on best play here otr, thanks
