After he left, he made a post describing exactly what he thinks happened, and while slightly far-fetched, he does make a good argument. The tl;dr is that she had a device that reads the rfid device that enables the viewers to see the action with cards up, and this device vibrates when she's ahead/winning. Garrett is well-respected in the poker community, and there are no shortage of videos where he takes beats with a smile and a polite "well done" sort of comment. Part of his reasoning is she flip-flops on her story/reasoning, and this play is not in keeping with her pattern of play up til this point. I think it's kind of close, because there are people that just do insane stuff at the tables and win like this legitimately, and by running it more than once, she absolutely risks "bad" runout where she loses both boards. Ultimately I have to side with Garrett though, the dude is super sharp, and with the amount of money he's won, he wouldn't make a big deal about it unless he was confident something fishy happened.
