Hi,
Welcome to chess.com. I hope you like it here and decide to stay. The "code" you are referring to is called algebraic chess notation. It's a litle more complicated than I am able to describe on this forum, but wikipedia has a good description of it here: http://en.wikipedia.org/wiki/Algebraic_chess_notation
I hope this helps, let us know if you have any more questions.
Sorry. Very new. Can someone please expain what 1e4 means and all that? Not understanding this makes this all seem like gibberish. Thanks for taking the time for a newbie.
