Memorizing Coordinates

Do anyone know how to memorize every coordinates of the chess board. Please tell me how. It can be helpful in a blindfold simul or a blindfold game.

The international chess school Blindfold training is EXCELLENT but I havn't done those for a while... when I did it helped a lot!

It is part of the GM package

Or... it means he hasn't studied enough yet.

Say fischer starts studying chess. He becomes WC later, but after 1 week or 6 months he is still relatively weak. He asks for help because he can't do something yet. Someone goes: Oh you can't? You must be training wrong.

Training takes time to work...

I think he is talking about memorizing the board...

and being able to play blindfold. I know he can notate fine...

I know him IRL

Lichess has an excellent tool for this:

Memorization of coordinates helps you notate and also play blindfold chess. Chess.com and lichess have both great coordinate trainers. 

Thank you all. To people who don't know what I mean. I want to play blindfold in the future and notate easily.

It's not that hard. First practice hard on cordinates drills, make somewhere 25-30 points at least.

Then start training like this: Close your eyes and you know by rule h1 square is light. So you go from there. Next to him must be black if its diagonal then white again etc. I started like this in after a month with less than 5 min every day before sleep i can succesfully say instantly every single color of square etc. You should do it more quickly ofcourse. And then you will be able to play blindfold chess. It helps your calculations and visualization

Play battleship for training.

The best ways I found, was to both record games in algebraic as often as possible, and also when studying games/puzzles, verbalize the algebraic coordinates of my proposed line of play. 

The lichess app is cool, but seems a bit disjointed from actual over-the-board thinking and play, as it just randomly throws squares at you to identify. Worth doing if you're really terrible at it, but ideally you get into a flow so stuff like N manuevers almost automatically flow out from you and you even know when the N manuever 'sounds wrong' if you choose the wrong square to land on. 

If you play through a lot of master games otb - which I highly reccomend - it will become more natural. Also try to use them as much as possible when explaining something or discussing games. Pretty soon you will have an internal map and you will be so familiar with the coordinates that you won't even have to think about it!

Playing blindfold is hard though. Keeping track of all the pieces in complex positions is a different story. I can usually make about 20 moves before I get lost!
