Grandmasters and Their Openings

I am currently learning the Urusov Gambit for white, and the Caro-Kann and Dutch defence for black.  Which Grandmasters' games could I look at to help learn these openings?

Also, I would like to learn a new opening for white.  Any suggestions?

Karpov is the king of the caro-kann if you go to chessgames.com they have over 250 of his caro kann games and as for white i don't know what ones you know but some nessacary ones are  queens gambit, kings indian attack 

For the Dutch there are 3 main variations that are quite different:

Classical (f5+e6+d6) - Alekhine, Botvinnik, Morphy, Larsen, Spassky, Korchnoi

Leningrad (f5+g6+Bg7) - Malaniuk

Stonewall (f5+e6+d5) - Alekhine, Botvinnik, Bronstein, Short, Jussupow (Yusupov), Radjabov, etc

Of course, many others have played those systems too. There have been some good discussions and articles on this site about the Dutch, just do a search.

The Urusov isn't played much by GMs these days but that doesn't mean it's not perfectly fine for our level. Here are a couple of good articles

Wow good links. I like well-written articles, even if they're in openings that I never play.
