FIDE Laws of Chess
F: Rules for play
with Blind and Visually Handicapped
Tournament directors shall have the power to adapt the following rules
according to local circumstances. In competitive chess between sighted
and visually handicapped players (legally blind) either player may demand
the use of two boards, the sighted players using a normal board, the visually
handicapped player using one specially constructed. The specially constructed
board must meet the following requirements:
at least 20 by 20 centimetres;
the black squares slightly raised;
a securing aperture in each square;
every piece provided with a peg that fits into the securing aperture;
pieces of Staunton design, the black pieces being specially marked.
The following regulations shall govern play:
The moves shall be announced clearly, repeated by the opponent and executed
on his board.
On the visually handicapped player's board a piece shall be considered
"touched" when it has been taken out of the securing aperture.
To make the announcement
as clear as possible, the use of the following names is suggested instead
of the corresponding letters, algebraic
Ranks from white
to black shall receive the German numbers:
Castling is announced
"Lange Rochade" (German for long castling) and "Kurze Rochade"
(German for short castling).
The pieces bear
the names: Koenig, Dame, Turm, Laeufer, Springer, Bauer. When promoting
a pawn the player must announce which piece is chosen.
A move shall be considered "executed" when:
Only then the
opponent's clock shall be started.
in the case of a capture, the captured piece has been removed form the
board of the player whose turn it is to move;
a piece is placed into a different securing aperture;
the move has been announced.
As far as
points 2 and 3 are concerned the normal rules are valid for the sighted
A specially constructed chess clock for the visually handicapped shall
be admissible. It shall incorporate the following features:
The visually handicapped player must keep score of the game in Braille
or longhand or record the moves on a tape recorder.
A dial fitted with reinforced hands, with every five minutes marked by
one dot, and every 15 minutes by two raised dots.
A flag which can be easily felt. Care should be taken that the flag is
so arranged as to allow the player to feel the minute hand during the last
5 minutes of the full hour.
A slip of the tongue in the announcement of a move must be corrected
immediately and before the clock of the opponent is started.
If during a game different positions should arise on the two boards, they
must be corrected with the assistance of the controller and by consulting
both players' game scores. If the two game scores correspond with each
player who has written the correct move but executed the wrong one must
adjust his position to correspond with the move on the game scores.
If, when such differences occur and the two game scores are found to differ,
the moves shall be retraced to the point where the two scores agree and
the controller shall readjust the clock accordingly.
The visually handicapped player shall have the right to make use of an
assistant who shall have any or al of the following duties:
Make either player's move on the board of the opponent.
Announce the moves of both players.
Keep the game score of the visually handicapped player and start his opponent's
clock, (keeping rule 3.c in mind).
Inform the visually handicapped player only at his request of the number
of moves completed and the time used up by both players.
Claim the game in cases where the time limit has been exceeded and inform
the controller when the sighted player has touched one of his pieces.
Carry out the necessary formalities in case the game is adjourned. If the
visually handicapped player does not make use of an assistant, the sighted
player may make use of one who shall carry out the duties mentioned under
point 9a and b.
