60/33 over 15 hands lol. Given he has over 2 buyins my default presumption would be that he's good. In any case I'd play this how I normally play JJ and that is see and shove most flops. The reason is that if you shove now you raise out all worse hands whereas if you call you get an extra-cbet from those worse hands. In either case you'll be stacking off against QQ+. Of course this only applies since you're in position postflop and if I were in the blinds I'd reshove preflop.
