portable game notation
PGN

that's right. If you copy the pgn file to the clipboard or save it to a file you can then paste or load it into many chess programs. This is useful for helping to analyse the game when its finished by playing each move through one at a time, getting the software to analyse the moves, and possibly annotating the game.
Hi All, Was curious what PGN stands for on the "Download PGN" button/link on my home page? Thanks,MMnI
