World Chess Network is a powerful chess game and also an online community for chess players from all around the world.

You can either challenge or be challenged by other players and chat with them during the game. Also, if you susbcribe to any of the two types of membership (Gold or Silver), you'll have the opportunity to access prizes, chess lessons, minigames and a wide range of other tools and functions.

Anyway, the free version allows you to test membership exclusive functions on certain days and, if you're not interested in them, you can always enjoy a funny, nice chess game.
