One thing I enjoy about progressing as a player is increasing my awareness of what is going with the other players in hands - in other words, getting the chance to make use of tells. I'm certainly not to the stage of pegging someone's hand when they eat the Oreo, but here's a story from a recent tournament where tells came into play.
NOTE: I made an error in the hand description in the video - the flop was two clubs not three. The river bought the third club, the 4 of clubs which paired the non club 4 on the flop. Sorry for any confusion.
