the only good reason
I play poker for money. this question, if thought about carefully, has only one answer. People can tell you its a hobby, or they play in non-cash games for fun. Honestly, think about it, be honest with yourself, and, you will find the same answer as me. You play for money. The only reason the game is exists is because people love to gamble, and people gamble for money. So it all boils down to the same thing. $$$$$ Anyone who answers differently is fooling you, or worse fooling themselves.
