Najdorf and white 0-0-0

Has anyone got any examples where white has castled queen side towards the end of najdorf opening?

Or just some of the ideas that this may invoke.

Cheers, Dave

ps game in progress so I don't want to be too specific in my question.

Check out some of the Chess.FM videos by John Fedorowicz and Larry Chrisiansen, especially those dealing with the English Attack. Also, look at Kasparov's recent victory with black over Michael Adams at Linares this year.
