Will a new domain name help rankings

[teachcsg]

If I purchase a domain name that links to my site with the new domain name being keyword specific....will that help boost rankings in Google? Reason I ask is that a particular website always ranks higher than ours because of their domain name (keyword specific). They are currently not even "open" and they still manage to rank high. I checked for links with the seomoz tools but did not see any high links etc.. Thanks!

So are you saying that you're thinking of buying a keyword rich domain name and redirecting it to your main domain.

I doubt that would pass any value.
