Don't question it. Just be happy with it. If nobody overplayed TPTK, poker would be a LOT less profitable.

I agree 100% - I put notes on this player that he will overplay TPTK.

I wish I could hack the server and see players notes on me and while at it look at their cards - just kidding FTP and the FBI.

I can not hack my way out of a paper bag but I would like to know what other players think of me.
