I think this is a slam dunk jam, given we don't block his auto folds like spades or clubs or light OESD that might peel turn, or Jx with spades. Guessing fair amount of weak Ax is capable of folding river to a jam as well. Just want to reaffirm my thoughts here and see if I am overlooking anything.
