The best way to prove this assertion is to compare poker, a game of skill, to casino games which have a built in house advantage. Even in a casino game which cannot be beat over time, a player?s knowledge of the game coupled with the discipline to control one?s emotions will benefit that gambler?s likelihood of winning or at least minimizing his loses. Now the same can be said about poker in regards to a player needing to be knowledgeable and in control of his emotions.
