Mistake #1: Playing too many hands

When people sit down in a game, they want to play. Often, this means they even will play hands like J 4. This is a cardinal no-no. Hopefully, the articles on this site will help improve your starting hand selection.

Mistake #2: Playing above your bankroll

This goes without saying. Sometimes the gambling and money aspect of poker gets to people too much. They become greedy and play in games they cannot afford or games where the competition is simply too stiff.

At first, stick to a consistent, lower limit. Learn how to play and beat the game before you play in higher-stakes games.

comes down to your willpower..
