Redirect chaining
It is important to use redirects when necessary, but there are VERY few instances where you will want to chain 2 or more redirects together. If you need to move a page that is currently being redirected from another location, you need to go to the original page location and change the redirect to the final location in addition to adding a redirect from the intermediate location. This will give you maximum benefit for the search engines in addition to helping any visitors that bookmarked to linked to the intermediate page.
