Blindfold training

In blindfold training, the player cannot see the complete current board. A starting position and later moves may be given, the visible board may remain frozen several moves behind, or all pieces may be hidden. The task is to retain every piece's location and update that representation after each move.

The central skill is visualization: forming and changing an internal representation of the position. This is not the storage of a perfect photograph. A player uses familiar relationships, such as defended pieces, unobstructed ranks, files, or diagonals, and pawn arrangements, to rebuild the board and calculate from it.

Gradual progression

1. Practice square colors and coordinates, meaning the letter-and-number names of squares, then follow short routes made by a single piece.
2. Memorize positions with few pieces and answer objective questions about their locations.
3. Follow short legal sequences, reconstruct the final position, and compare it with the real board.
4. Solve a tactics puzzle, a position with a concrete solution that must be calculated, or play a partial position with the board hidden, increasing the length only when reconstruction is reliable.

Accuracy matters more than duration. When the mental position is lost, stop, reconstruct, and check instead of continuing to guess. The practice can support calculation and board memory, but it does not replace normal study with visible pieces or prove superior understanding of long-term plans by itself.

A fully blindfolded training game is an advanced form, not the starting point. Partial exercises make it easier to determine whether the difficulty lies in remembering the position, updating it, or calculating consequences.
