This is another game in which I played blindfolded, this time with an increment, and I am quite surprised in how well I am doing in the opening, even blindfolded, in this game I blundered an easy tactic, that of course playing normally I am quite sure I would have seen, but that's why we train to be able to see this tactics even blindfolded.
How Practicing Blindfold Chess Boosted My Visualization

This is the guide, to play blindfold chess: https://youtu.be/0VuQhJT7iDk

Another analysis
I did about a blindfold game, I have introduced this into my training plan in a consistent way: it was a bit dissapointing the disconnection of my opponent since I play just 1 blindfold game in my training plan

a game I played blindfolded: I still have trouble to visualize correctly the board, and I get confused where my pieces are, but I am slowly improving in it: https://www.chess.com/game/138826304790

another blindfold game, of my training plan, I blundered a pawn in the opening and it just went from bad to worse, and I could not make a comeback, I even hung mate in the end:

@bunchofZs(I’m not counting them sorry)44, that’s still a pretty good game though! Impressive, for blindfold. Do you try to play more unrated games/are your opponents also playing blindfold?

I play a normal rated game and I put my pieces in blindfold mode, I have in my training plan 3 days that consist in 1 hour of tactics and then a blindfold game

I usually analyse games, then after having finished my study session I learn the game by heart. When I am travelling I replay the games blind. The advantage is that one needs to figure out the reasons behind the moves, so everything makes sense.

Does this work with the blindfold chess variant on chess.com?
i wouldnt say it would be as efficient, since you can still see the layout of the board

Some time ago, I stumbled upon a web app called "Chess Memory Trainer" which allows you to practice visualization.
I haven't used it regularly but I think it could be very useful. Chess.com could incorporate such training tools.

I honestly do have plans for this actually! Because I see the point, you're trying to visualize a board, with a set amount of pieces, constantly. This is my problem too, whenever I go into a puzzle, I try to solve it visualizing just like that, and then I find myself stuck because I can no longer visualize from there, I have to restart over.
Honestly this makes sense and I would be eager to try it: do you have any blindfold tutorials or a step-by-step guide to this?
