What is the Monroi? What does it do, and how do you know what to do with it? Good luck with your games!!
The Monroi is just for chess notation. Except it's more visual than the standard notation sheet. Instead of just seeing "b3" on the notation sheet, you'll see the pawn go to b3. This streamlines the chess coaching process in that you don't have to get the board out and play through all the moves after a tournament game. Lots of the serious younger players have them, though most adults do not. Not sure if it is a technology phobia or a simple "I can do it the right way" sort of attitude. :)
