Hey man,
Just my thoughts here. I don't think he's ever doing this with AA. Easily something like AK, AJ. With what you've said about him, I don't think I'll ever fold this.
Looks like he's doing this more with a medium strength hand to try and get you off the pot (imo he could also do this with AT+). Personally I think you could easily ship it here, or play c/c again if you think he would fold out.
But let's see what veriz says, I'm interested
