What is your favorite non-playing Chess Website? This site, is of course, the best place to play. but where do you go, to study or just have fun?

For me... I would have to say Chesslab

I only go to chessbase to see the latest chess news, and chessdirt because of Meg's wetty sense of humor..

I analyse only my games and that's how i improve.

The best site for learning the openings is -   http://www.eudesign.com/chessops/

I stumbled upon it a few years back and spend alot of time there improving my opening knowledge.

A good partner to Chessops is this site on opening statistics- 

http://homepage.ntlworld.com/adam.bozon/stats.htm

Scroll down past the opening statistics to see some added features

Excellent...

"Stumble Upon" is a great way to peruse the many chess sites. You just need to designate Chess as the stumble topic. I've lost count of how many chess sites I've found with this method

I am biased but I check the KWA site (www.kwabc.org) as well as Chessbase and Winter's Chess History site.

I spend quite some time on www.chesstempo.com practicing my tactics. The last few days they have started with endgame puzzles aswell, Haven't spent alot of time on those yet though.
