I don't think Phil was shooting angles. I think this was a careless moving of his cards. Say what you want about Hellmuth, but he's not known to be an angler.
Still, it's understandable why his opponent believed it was a fold, especially because the guy was a rec player. Big poker badass Phil should have realized what happened, and just given the guy the pot.
Careless moving of his cards? He slid them face down in a forward motion. With no audio or any other thing, the video alone is a pretty damn clear fold. The announcer even said fold. The all in player immediately tapped the table as to say nice hand. Thats a fold.
It's hilarious that we as a society think everyone can be a dr, a lawyer, an engineer. Some people are just fucking stupid. Why can't we just accept that?
