I played in a charity tournament, put on to help the Jimmy Wilborn with his precinct 2 campaign. The buyin was $150, with $25 rebuys. I think they had about 150 people. The first prize was a trip to Cancun. I don't think there were any other prizes.
The tournament was very well-run. I think they used "Casino Knights" or someone like that. They provide tables, chips, cards, dealers, etc.
Unfortunately, they provided a free bar, which was my undoing...
We started with 10K in chips. By the end of the hour long rebuy period, I managed to get up to 40K in chips. I did an add on as well. I was in pretty good shape. This was especially true considering quite a few of the players were pretty inexperienced.
Unfortunately, I threw away all my chips on the second hand after the rebuy period. It was an unraised pot (yeah I know). I flopped top pair and inexplicably went all in after two people checked. The guy to my left called - he had me covered and his nut straight crushed me. Oh well.
I don't know who won - I left and checked out a cash game.
