If you are just starting out, and you know the rules and played a few games, I'd recommend these youtube videos [1] by John Bartholomew. Youtube has a bunch of other good videos for beginners, e.g. chessnetwork, st louis chess club, etc. Also, I wouldn't bother learning strategy until you get to like >1500 rating or so. If you get really good at tactics, you can get to 2000 without having much strategic understanding.
