Lots of good books. Coach Heisman loves a good instructive anthology. Here's his book list:

And of course free Chess Mentor courses are a hard deal to turn down. They really are well done, although you'll need to review them a few times to be sure the lessons "stick". Should keep you busy for a few weeks!

What steps should a beginner take to move to the next level? Are there any books that will benefit me? If so, were to start, e.g., an Opening, Stratergy, or Tatics book?
