I stick it in here. You say he can't have AJ or KQ. Can he have QQ+? I doubt it, and you are getting odds from the blinds and antes. If you think his range is mostly pps, you could always stop and go and hope he makes a bad fold.

But I've seen weird raises like this from all kinds of weird crap before: people get fancy when they have a stack this size, trying to get extra fold equity (and obviously here he got it). I would just push and wouldn't think twice about it.
