Chess openings on the web?


Hi, does anyone out there know any good site with good opening literature? I'm looking for something about grand prix opening but a site with info about most of the openings would be good. I'm looking for a site with text and so, not just 1e4 c5... explainging what to think about in the openings and so on.



Thanks this site is greate, if someone has another site so please add.


I've found Wikipedia surprisingly good (depending on what you're looking for).
