I wanted to put this question out there on how much blindfold chess all of you have done, or are able to do?
Currently, I've been working on developing blindfold chess abilities for about 11 months, working about an hour or two a day, and I'd say that currently, I can play about 1 move (2 ply) blindfolded. If I move one pawn or one piece, I can pretty much derive the characteristics of the new position without looking, but further moves than that, and I lose the ability to remember and process the board. But I'd say I've made great progress to get this far. Before I started, I couldn't even process an empty board, much less a board with 32 pieces on their starting squares. But I have some techniques to arithmetically derive each square's characteristics (diagonals, knight moves, etc.), such that I can navigate an empty board. I've been working on blindfold chess training for so long at this point, that all my dreams are about doing blindfold chess training, and I sometimes wake up in a cold sweat from having done a knight tour or something wrong in my dream.
Anyway, I was reminded of this question, because I was watching a podcast today at Author and Top Trainer GM Wojciech Moranda on The Key Components of Chess Calculation, where the guest (who happens to be Levy Rozman's coach), mentions his puzzlement at people who, instead of visualizing the entire board at once, visualize the board in quadrants "for some strange reason":
17:43 I had this one student who said that he didn't view the board as a whole, but he would visualize the board in quarters for some strange reason.
And how for him, it's a "dopamine rush" playing blindfold. I hope to someday also feel this dopamine rush playing blindfold! Maybe not blindfold blitz like this fellow does though, since I'm terrible at blitz, having a blitz rating of only 185.
18:26 On the higher level, however, visualization training takes rather the shape and form of playing blindfold games, I guess, right? So I mean, I've been always enjoying blindfold, but I also know a couple of title players who somehow find it particularly difficult to play just without looking at the board at the same time. I particularly love blindfold blitz, right? So I mean, obviously, when I'm not looking at the board, I'm going to need some assistance from a helper, like a person whom executes the move instead of me. On the other hand, it's like fun. It's like, like, it gives me a nice adrenaline or dopamine rush also when I when they get an opportunity to play like this.
