In my few years of playing I can honestly say the only tells i play off of are betting patterns.

I play live games quite often and the people who play, play every hand alike. Their hands don't shake, they dont laugh, they dont smile, they dont breath. Just look.

Now i have read Mike Caro's book which i think is shit and it cost me a lot of money trying to use those bs tells but anyway, the way a person bets is the only surefire tell i know of.

If you did have a crazy tell on somoene beside their betting pattern, post it here and tell us how you found it out.
