Carlsen against 3 blindfolded with the clock.

Just want to point out, by itself, playing 3 blindfold games at once isn't even close to world class... but
having all games on the clock and letting them move whenever they want makes this much more difficult than otherwise. Very impressive.

it's simply amazing how can someone keep so many data in mind at the same time. I couldn't do it for even 3 moves! I wonder what this may do to someone's mind, I mean who has not any natural gift for this. long time ago, in the clubs, friends adviced me not to try blindfold playing, because it would drive someone crazy. I observed how calm and easy Carlsen was in that presentation, and he has also to deal with laughs, comments, and so. Not so many things to distract him, I suppose. But really, that's how I can realize I don't have even a small chance to play and win chess with someone like Carlsen. I really liked that video. And I'd really like to shake hands with him and say congratulations, someday.
A big part of it is he doesn't have to remember individual moves. Each move tells a story and is part of a larger pattern, so he only needs to remember a few things for each game. IIRC psychologists call this "chunking" for example a fianchetto kingside formation may be one chunk of data instead of 6 individual pieces.
They did a fun demonstration of this with Polgar where they had a truck drive by with a chess position on it. With only a few seconds to memorize the position, she easily remembered the positions when they were taken from real game (that is to say, the piece placements made sense and could be divided into chunks) but when shown random positions she couldn't remember them.

In a similar blindfold demonstration (you should be able to find it on youtube) Carlsen tried 4 or 5 at once. One of his opponents made a lot of nonsense moves and Carlsen admitted that 1) it was the hardest game for him and 2) he actually couldn't remember where all the pieces were for that game.

Undoubtedly Carlsen has talent for chess, whatever that is exactly. But for almost anyone who has put in the same work he has, chunking is 100% possible, and playing multiple blindfold games would also be possible.

I had imagined something like that, those chunks, as for example, in a game where book moves of an opening was played. Realy, he would have just to remember the variation name and the move the player did last, I think. Thanks for the explanation.

Thanks, I clicked, I will take a look at those videos later.
Most of you may have already seen this. I only saw it now. Impressive.
