Sure, lets do one more. But I'm gone for tonight.
The notation isn't too bad when you get used to it. Its main drawback is, I think, that the same square on the board actually has two notations denoting it, depending on if you play black or white. Much better that one square is e4, rather than both K4 and K5. I guess the modern notation is a bit more efficient as well. 1. Nf3 is a bit more to the point than KN1-KB3. You now at once what kind of piece that is moving and you get the square in one go. But the main drawback is of course that using the old style is getting the player more and more isolated from modern books, talking chess, etc.
But it is handy to know the old stuff in case you want to read some good old dusty but classic book on chess.
