This guy is a complete donkey - WTF is he doing here? His flop lead is inconsistent with him slowplaying a monster like JJ. Then, he slows down on a blank turn, leading me to think he has something like AdKd/AdQd, but he fires back at me. AA and KK are obviously in his range given these moves, but am I good often enough to call?
