Michael Haag did a 3-year stint in federal prison due to drug charges. He learned to play poker while behind bars.
Here's the background story on him: https://www.pokertube.com/article/ex...oker-in-prison
He also has a Jiu Jitsu background.
Since leaving prison, he has become a low-mid stakes poker pro, and lives in Vegas.
He was playing at Venetian, with vlogger Jeff Boski, and got up to go to the bathroom.
He then witnessed an argument between a guy and girl, and saw the girl smack the guy on the shoulder. This enraged the guy, and he punched the girl in the face.
Haag decided he had to act, so he jumped on the guy's back and attempted to put him in a sleeper hold. This actually worked, and the guy fell asleep. However, the girlfriend wasn't grateful for the help, and attacked Haag, yelling, "Let him go!!"
Eventually others showed up to help and separated the girl from Haag.
Security considered 86ing Haag for this, but people spoke up in his defense, and he was allowed to stay.
