I'd go back and edit the original post and give each question a number to make it easier to specify each answer.
1. Yes, it does help your normal chess.
2. Most of my visualization comes from patterns and angles rather than actually seeing a board with pieces on it. But I'm sure higher rated players could tell you more about how it's REALLY done....
3. I guess. I have something similar . Most of the time when I play against someone in blindfold (I don't have much competition around here) the game is over within 15 moves because they either blunder a checkmate or keep making illegal moves i.e. moving a bishop across a blocked path.
4. I suppose this would give a pattern to what you're trying to see and give it a more spatially recognizable conception. But I've personally never heard this before. It's an interesting idea....
That's pretty much all I've got. Most of it probably isn't helpful
I have recently come across the idea of blindfold chess. Please keep in mind that my questions are more geared toward chess visualization rather than the actual playing of chess blindfolded. I would be very grateful if you guys can help answer a few of my questions:
Does practicing/learning blindfold chess skills help your (normal) chess-playing ability at all?
What helpful method do you use to help you visualize the board and the position?
In my few attempts at visualization, I find that I can't even "see" the board; instead I see the "ghosts" of pieces [I can sense them but not see them] suspended in midair. Is this normal?
I have heard of the idea of memorizing the color of squares. I don't see how it's useful. (After about five minutes of trying to figure out which square is which color, I found out that if you give a number to each letter, 1 for a, 2 for b, and so on, then add the two numbers together, you can figure out the color. Even numbers are black squares and odd numbers are white squares, but I digress.) How does knowing the color of the square help visualization, if at all?
That's it for now. I may ask follow-up questions if necessary. Thanks again for your input!
