This is a PGN. PGN stands for Portable Game Notation. It contains all the major information in a game and the moves played. As you see below. I would say that it is much more important to learn Algebraic Notation. Such as how to read and understand what this means 1.e4 e5 2.Nf3 Nc6. They look the same yet aren't Algebraic Notation is how we write out the moves PGN is how we write out the entire game, with who played, their ratings, when, etc, etc.

I was having a discussion with a friend of mine and he told me that until I learn PGN and be able to look at PGN and move the pieces in my head my game would be limited and I would never reach master standings. Is this true and if so where do I begin?
