I think the best method would be to just send them a message on FB and ask if they want to play with you.
If you have some friends who already know how to play the game, perhaps share a game of yours with them. After you finish your game (or you can go to your archive), you can click the share link and then share it on FB and other social media sites. See attached screenshot (it might look a little different on your screen if you aren't on the new v3 server yet, but the option is still there--and you can access the new server by clicking the Try the New Chess.com link at the bottom of any screen when you are not logged into live chess).
i do not have a good rating and wish to play with my facebook friends firstly. so this question....
