All-In-Entertainment is a company who hosts free entry No Limit Texas Hold 'Em poker tournaments Valley-wide at area bars every night of the week. Depending on the day-of-the-week, you may have up to 12 options where to play in a tournament around the Phoenix metro and they typically have at least one selected bar in every reach of the Valley -- even the sticks like Goodyear, Surprise, and Peoria.
Back when this company started during the NL craze [maybe in 2005 or so], there were masses of people nightly at each spot. Now, attendance has died down a bit, but there are still plenty of participants and a semi-regular tournament of the board leaders to showdown against each other for prizes like, oh, entry into the WSOP satellite events. Yeah, kind of a big deal.
The dudes who run this impress me as they have really built up their business despite the fleeting phenomena of NL Texas Hold Em, but it appears they are still going strong ... and that small venture that started in Phoenix has expanded to 7 other cities in 4 other states, including Oregon and California. Pretty impressive.
If you want some practice for Vegas, you should use the opportunity of going against real-live competition for minimal risk [actually, no risk, as it is completely free except for the beers and possibly food you buy at whatever local pub you happen to be playing at -- and you should bc its how they keep their business thriving]. IMO, it is much more valuable of a Vegas prep than going against some aggressive online dweeb in Elk City, Oklahoma.
