Here are a couple more links to a couple backgammon sites that provide a ton of information as well as being very useful.
The first link Chicago Point does a very good job of keeping track of tournaments around the world as well as articles about strategy etc.
The second is a link to Kit Woolsey and his site Gammon U. Very good articles on strategy as well as having one of the more famous online match of the day. Kit moves then the community votes on the proper move and or cube decision.
Always wanted to use this for something and now is my big chance.. top sites in google search for backgammon.
