One of the reasons, amongst several, for chips is to help you seperate the idea of money from the game. When the game was played before chips, I imagine the emotions ran much higher. It was real hard currency that was played.
Here is where PlayChips come in real handy. I have always taken PlayChips seriously. Granted Play Money games are not to a calibur of play that real money
games are. However it is a cheap way to learn an awful lot about the game. One of the things I learned, finally, was to seperate the idea of money from chips.
No one loves getting bad beat. Even with play chips. However, I don't mind getting beat in a hand with 2 or more great hands. It's the cheap suckouts that drive us all a bit tilty.
The important thing is to seperate the notion of chips=money out of your current thinking. As so many here will tell you, DO NOT BE RESULTS ORIENTED!. Rather concentrate on making good decisions, and finding the self control to act on those good decisions. Remember it can easily be a fold that is the best decision.
