Put it all in. If you lose on the river when his AK-AJ/KQ-KJ pairs, oh well.

The massively oversized PFR in the early levels usually seems to mean big non-pair. They think they have a good hand, but they always seem to get outdrawn, so they want to blow everybody out (and win a whopping 45).

Quite possible also he believes the pot is rightfully his no matter what his cards, just because he made the first move at it. He has J2o and will battle to the felt with it, because you're just trying to steal it from him.

In the early levels on Pokerroom you're way ahead way more often in this spot than you're running into AA-JJ. Maybe a steal that made some freaky flop catch, but I suspect if Villain really had a hand he wouldn't have been able to resist raising you on the flop.
