When I started playing poker, I played hard for virtual chips. I don't play right now. There is no need for this. At that time in the past it was the time of learning the game of poker.
I don't and I don't really see the reason to do so!
1) You can't win anything.
2) Since you can't lose anything either, I feel that people don't play it serious, so what's the point? You can't really learn or train from it.
