It is not an impressive feat to win at a game that only you are playing. The people he tricks are not actively trying to not be fooled. They are ignorant. What does it say about a person that picks on the weak and stupid?
Im not surprised that a moron like you would hold such an opinion, I hope that was sarcasm. I have spent time with Jim, and I know his capabilities well. I can say from experience that scamming takes little more than sparse intellect on the human mind. Anyone with a mind could attain such minor intelligence because we all have minds ourselves, though some less than others.
