The pieces vanish: follow their moves in your head, then answer.
Blind Moves is a blindfold chess trainer that starts easy. You study a position, the pieces vanish and moves stream in one at a time. Then comes one question: where a piece stands now, what is on a square, or which pieces attack it.
Level 1 is a single move you watch glide across the board. Each level changes one thing: Black starts to move, the arrows fade to a glow and then to the move name alone, captures, kings and pawns join, and the stream grows to 15 moves by level 41. By then you are following a game blindfold.
Every calculation is blindfold chess in miniature: you move pieces in your head and trust the picture. A typical first run here ends around level 12; level 16 is the top quarter (Club) and 31 the top 1% (GM).
Blindfold play needs the square names without thinking, which the chess coordinates trainer drills, and a memory for pictures, which the visual memory test measures.
Yes. Most players start by following a few moves without the board and add more as the picture holds. That is the path this trainer takes, one step per level.
Follow moves without moving the pieces: replay a game in your head from its notation, solve puzzles without touching the board, and name the squares a piece can reach.
Not at first. You see the position before it vanishes and answer one question per level. The later levels, with long streams and the move names alone, come close to following a blindfold game.
