Garry Kasparov vs Deep Junior Match
New York, January 26th - February 7th 2003
1. Arbiter: an arbiter will be appointed by FIDE, subject to agreement
between the human player and the machine team to ensure the smooth running
of the match and to enforce the match rules.
2. Laws of chess apply: unless explicitly specified herein, all
the FIDE Laws of Chess apply to this match.
3. Time control: 2 hours for the first 40 moves, an hour for the
next 20 moves, and 30 minutes for the rest of the game.
4. Program operator:
a. An operator will make the moves for the machine on the chessboard as
well as operate the game clock, enter moves for the machine and, except
when the machine is in time trouble, keep a written record of the moves
of the game.
b. The operator will have a computer screen, a keyboard and a mouse on
or near the game table
c. The machine operator may be changed between games
d. The machine operator may not be changed during a game
e. The arbiter will treat the machine operator as representing the machine
f. All repairs, recovery work, and the machine team discussions must take
place with minimal disturbance to the human player. No one other than
the operator, the arbiter, and the human player should be on the stage
when the clock is running.
g. The operator should be viewed as a mechanical extension of the computer
and as such should have little or no influence on the outcome of the game
other than described explicitly below. This is a guiding principle that
can be used in the resolution of any disputes.
5. Accessibility of the machine display:
a. The arbiter has the right to view the operator's display during the
b. The arbiter or match technical supervisor will keep a log of all machine-related
actions during each game. (E.g. clock corrections.) This log will be reviewed
by the committee and released after each game.
c. The human player does not have the right to view the machine's display
during the game.
6. Operator allowed actions: After the first game move is made
by the machine, the operator will restrict his actions to those that enable
the game to be played according to the match rules.
a. The operator will enter the human player's moves.
b. The operator will execute the machine's moves on the chessboard and
press the clock.
c. The operator must update the machine's internal clock according to
an algorithm presented to the arbiter before the start of each game. If
no algorithm is given to the arbiter before the start of the first game
then the operator MUST adjust the computer's internal clock to the game
clock when a move is being entered and the clocks differ by two minutes
or more. For any game subsequent to the first game if no new algorithm
is given to the arbiter before the start of the game then the algorithm
in force for the previous game shall apply.
d. Following an operator error or technical problem, the operator, when
instructed to do so by the arbiter, may make any input to allow the game
to resume and continue, including change of position, resetting of the
internal clocks and any other reasonable action.
e. The operator may not force the machine to move when the machine is
on move nor may the operator delay the execution of the machine's moves
nor may the operator delay the inputting of the human player's moves.
f. The operator will resign, offer, accept or decline draws on behalf
of the machine, all in accordance with the terms of Clause 9 of these
g. The restrictions on operator actions will not apply before the machine
makes the first move in a game.
h. Other than as specified in sub-clauses a-g above the operator may not
change any of the machine parameters during the game.
i. The machine team members are permitted to make any changes they wish
to the machine between games including changes to the openings book and/or
k. The operator shall conduct himself with the etiquette normally expected
in top class human chess events.
l. If a parameter is set incorrectly by accident before the start of the
game or during a stoppage for a technical problem the operator may request
a technical break to correct this parameter setting and the arbiter shall
decide, after consultation with the arbitration and rules committee, whether
to permit such a correction. Such a change should only be permitted in
exceptional circumstances, for example if the operator accidentally set
the machine to play at blitz speed.
7. Operator errors:
a. The machine's move selection, as displayed on the machine's screen,
take precedence over the operator's moves on the chessboard
b. If the operator has completed a move on the chessboard and it is not
the move the machine made, the operator will notify the arbiter as soon
as possible, show the arbiter the machine's move on the screen, and re-enter
the correct move.
c. If the operator completed a wrong move and also pressed the game clock,
the arbiter will allow the move to be corrected on the chessboard and
will allow appropriate time compensation to the human player. 10 minutes
extra thinking time will be added to the human player's clock for the
first infraction in a game. In the case of a second infraction in the
same game the game will be forfeited by the machine.
d. The rules of chess for touching pieces and "J'adoube" will
not apply to the machine operator provided that these rules are not violated
to such an extent that it constitutes disturbing or distracting the opponent.
e. In case the operator erred in entering a move to the machine, the operator
will immediately notify the arbiter and show him the machine's display.
The arbiter will then authorize the operator to correct the position and
enter the correct move and adjust the players' clocks if necessary.
8. Technical problems:
a. Other than catastrophic problems covered in 8b, all failures and repairs
are treated equally. The machine team can do whatever they deem necessary
to restore the machine and this shall be done while the machine's clock
is running. The machine team has to restore the machine as accurately
as possible to its state prior to the failure, as determined by the configuration
submitted to the arbiter prior to each game. (This configuration document
defines the values of all program parameters that can set by the operator
and will also be available to the match committee.) All work and discussion
will take place in the presence of the technical arbiter/supervisor who
should keep a complete log of all work done. The technical arbiter/supervisor
should always have a complete understanding of what the machine team is
doing and they must make all of their activities clear to him, but not
while the computer's clock is running. Any explanation required by the
technical arbiter/supervisor and any information needed in order to facilitate
the keeping of the complete log of work done must be provided while the
computer's clock is not running. Should the technical arbiter/supervisor
decide that he needs information at a moment when the computer's clock
is running he must first stop the computer's clock, then make the request
for information, and only restart the computer's clock when he is satisfied
he has received the necessary information.
b. A power failure (or other external disruption) shall be treated as
a force majeure and the game shall be suspended until power is restored,
at which time the arbiter shall allow the machine operator up to 20 minutes
to reset the machine and resume play. At the end of this 20 minute period
the arbiter may restart the machine's side of the game clock.
9. Draw offers and resignations:
a. The machine operator has discretion in accepting or rejecting draw
offers by the human player.
b. The machine operator has discretion when and whether to resign on the
c. The machine operator may seek advice from other machine team members
in considering draw offers. Prior to the start of each game the machine
operator will provide the arbiter with the names of those persons who
are considered to be part of the machine team for that game.
d. The machine operator has discretion in offering draws, provided the
machine is showing draw or near-draw evaluations or displaying repetition
lines. The machine operator will not offer a draw if such conditions are
not met, but may accept a draw if offered by the human player.
e. When a draw offer is made by the human player, the machine's operator
will promptly enter the human player's move into the computer. The machine
team may start consultation at this point (off stage), viewing whatever
is on the machine's screen. If the machine makes its move before the operator
has accepted or declined the draw offer the operator must immediately
return to the board (if he has already left the board) and make the machine's
move on the board - this constitutes rejection of the draw offer. The
operator may then leave the board to allow himself and the other members
of the machine team time to finish their contemplation as to whether or
not, in principle, they want to agree to a draw and after no more than
ten minutes consultation time in total, including any consultation time
taken before the draw offer was declined, the operator must cease his
consultation with other team members. If the operator wishes he may then
offer the human player a draw when making the next move for the machine
or on any subsequent move.
10. Etiquette regarding draws:
a. The contestants voluntarily take upon themselves to observe etiquette
in agreeing to draws without capitalizing on their opponent's inherent
weaknesses, i.e. the human player's tendency to tire in a pointless game
of many moves, and the machine's tendency to lose time through the time
taken by its operator to input the human player's moves. Should a position
be reached which is in the machine's endgame databases and if the result
from that position with correct play is a draw, then the game ends immediately
and the machine operator must promptly advise the human player and the
arbiter that the game has been drawn.
b. The contestants agree that the likelihood of making a mistake in a
complex position is a legitimate reason for refusing a draw.
c. The human player acknowledges that the chess understanding of the machine
operator is much less than his own and ultimately the operator must rely
on the machine's judgment regarding draw offers.
11. Non-intervention in the machine's play:
a. The machine's move choices during a game will be made exclusively by
the machine running on-site and may not be influenced by any external
computer or chess expert.
b. The machine will not be connected to the Internet or to any other equipment
such as a telephone or radio communications device or another computer.
c. Except due to a technical problem, no technician or other person will
handle the machine or connect or disconnect cables from it, other than
as allowed for in the above rules.
12. Arbitration and Rules Committee:
a. An Arbitration and Rules committee made up of experts acceptable to
the human player and to the machine team shall be responsible for interpreting
technical questions as they pertain to these rules.
b. In the event of a technical problem or dispute the arbiter shall consult
with the arbitration and rules committee and must accept the committee's
conclusions as to all technical matters and as to the interpretation of
any of these rules.
c. The decisions of the arbiter shall be bound by the opinion of the Rules
and Arbitration Committee and shall be final and binding.
13. Log files:
a. As soon as is reasonably possible after the conclusion of each game
and preferably within 30 minutes thereof the machine operator shall provide
the arbiter with at least two electronic copies of the machine's log file
for the game and, if requested by the arbiter, a printed copy.
b. The arbiter shall be responsible for passing one electronic copy of
this log file to each of the members of the Arbitration and Rules Committee
as quickly as possible and, if requested by the committee, one printed
copy for each committee member.
c. The log file must include sufficient information to enable the Arbitration
and Rules Committee to examine such details as each iteration of the machine's
search, the evaluation for each such iteration and the time taken for
making each move.
d. A copy of the program used for each game shall be given to the arbiter
within 30 minutes of the end of the game in order, if necessary, to allow
the match officials to recreate a game situation. The arbiter will keep
copy confidential and will not distribute it to any person either during
after the match.
e. The log files will be kept confidential to the arbiter and the Arbitration
and Rules Committee.
a. The human player shall be provided with an executable copy of the program
as used in the program's most recent official competition or, if more
recent, as at the date six months prior to the start of the match.
b. The intent of these rules is to create a fair environment for both
human player and machine. Any situations arising that are not explicitly
covered by these rules shall be dealt with in such a way as to be fair
and equitable to both parties.
c. In any circumstances not anticipated explicitly by these rules the
Arbiter, after consultation with the Arbitration and Rules Committee,
will determine the best course of action.
