Chess Openings

Most chess games can be divided into 3 sections - the opening, the middle game, and the end game.  Depending on which moves are played, the opening may take 1 move or 17 moves.

Over the centuries, chessplayers have discovered that some openings work and some openings don't.  They have even devised a notation for famous chess openings known as ECO, which is short for Encyclopedia of Chess Openings.  Here is a list of some well-known openings.  Note that there is not general agreement as to which ECO code or opening name applies to certain openings, especially those that are arrived at by transposition (i.e. 1 d4 e5 2 e4 transposes to the same opening as 1 e4 e5 2 d4).  Not every named opening is listed here - for a more complete list, go to http://www.theandrew.com/projects/programming/chessdb/ or http://www.abortionessay.com/eco/.  If you don't understand the notation given here, review the rules and specifically read the section on algebraic notation.
