I once played poker in a Reno poker room. It was structured betting, not all in madness like on TV. I was probably 21 and sitting down with a mixed group, but mostly old timers. I was not new to poker, but I occasionally got the allowed bets wrong. I did really well that night. It could have been luck but I like to think I gamed them with my behavior, by pretending to be stupid. Like in a Guy-Ritchie movie plot twist kind of way.
