1. The rate of play shall be 40 moves per player in the first two hours of that player's time, then 20 moves per player in the one hour of that player's time, then all remaining moves in an additional 30 minutes per player. Any time not consumed during the first period is carried forward to the second period and any time not consumed from the second is carried forward to the final period.
2. Kasparov has the right to choose the chess clock utilized during the match. In the event that there is a faulty clock -- and if a replacement of the same type of clock is unavailable -- the ACM has the right to substitute a chess clock of a different type.
3. During the opening ceremony, Kasparov will draw lots to determine his color in the first game of the match. Thereafter, the colors will alternate, irrespective of game postponement or forfeiture.
4. Deep Blue shall be operated by an operator provided for this purpose by IBM. Supposing that it is not Kasparov's turn to move, the operator may be replaced at any time during a game or match at IBM's discretion.
5. The operator, at his option, shall sit at the chess table facing Kasparov. Although the operator is free to move about in a non-distracting manner when it is Deep Blue's turn to move, the operator may not leave the table or move in a distracting manner when it is Kasparov's turn to move.
6. In the event of a technical fault or problem in any way relating to Deep Blue, the operator may, provided that it is not Kasparov's turn to move, communicate with any person he chooses during the match. This must be done in such a manner as to avoid any distraction that may reasonably be regarded as disturbing to Kasparov.
7. When it is Deep Blue's turn to move, Deep Blue's chess clock must remain running at all times -- even in the event of a technical fault (excluding power failure or other conditions that make the game unplayable) that prevents Deep Blue from performing a move in the regular manner.
8. When Kasparov has made his move, the IBM operator must promptly communicate this move to Deep Blue via equipment provided for this purpose. This equipment is to operate in a manner that cannot reasonably be regarded as disturbing to Kasparov. In addition, the operator is required to promptly communicate to Deep Blue information about draw offers and refusals.
9. When Deep Blue has chosen its move and communicated it to the operator, the operator shall make Deep Blue's move on the chessboard then press Deep Blue's side of the chess clock.
10. If the operator makes a mistake, either in communicating Kasparov's move to Deep Blue or in making Deep Blue's move on the chessboard, and after said mistake is discovered, the position immediately before the mistake is to be set up on the chessboard and the player's clock times are to be adjusted.
If it is possible for the arbiter to determine the proper times that should be displayed on the players' clocks, then the arbiter shall adjust the clocks accordingly. If this is not possible, then each player shall be allotted a time proportional to that indicated by his clock when the error was discovered such that the proportion is the same as the ratio of the number of moves made by that player up to the time the error was made divided by the number of moves made by that player up to the time the error was discovered.
In addition, Kasparov will receive a recovery bonus of five minutes on his remaining clock time to compensate for the disturbance caused to his concentration.
11. At any time during the game, when it is Deep Blue's turn to move, the operator may indicate to Deep Blue how much time remains on either or both sides of the chess clock.
12. If, during play, Deep Blue is unable to perform in the expected manner -- for example, if it is unable to accept a legal move -- then the operator may set up in the computer the current board position and status along with the clock times of both players and any other information required by the program. All such work is permitted only while it is not Kasparov's turn to move.
13. At any time during play, IBM may replace any or all of the computer hardware and/or software being used to play the games provided that:
a. Any work carried out in the playing hall is absolutely necessary, and
Any work that can be carried out via the mirror terminal in the Deep Blue control room shall be carried out there. In the case that work is necessary to perform maintenance in the playing hall, Kasparov will receive a recovery bonus of five minutes on his remaining clock time to compensate for the disturbance caused to his concentration by the on-site repairs.
b. All work is carried out only when it is not Kasparov's turn to move.
14. The operator may offer a draw, accept a draw or resign on behalf of Deep Blue. This may be done with or without consulting Deep Blue.
15. Kasparov and the operator shall both keep a written record of the moves of the game at least up to move 60, after which scoring is optional.
16. In all matters concerning the laws of chess and their interpretation, the decision of the arbiter shall be final.
17. The arbiter shall be appointed by the ACM and shall be a person who is acceptable to the ACM, IBM and Kasparov. If the appointed arbiter is unwell or unable to officiate for any reason, then the ACM may, at its sole discretion, appoint a replacement arbiter but shall -- if practical -- consult with the players or their representatives over the choice of the replacement arbiter.
18. The ACM shall be responsible for resolving chess rules during the match and shall be responsible for the appointment of the arbiter. The ACM and the arbiter shall have the responsibility to oversee and officiate the six games comprising the match.
19. In the event Kasparov or IBM disagrees with a decision of the arbiter, the ACM Appeals Board will be called upon to make a final decision.
20. The ACM Appeals Board will monitor the playing hall and accessory facilities used by both sides to ensure compliance with match rules and to ensure that no inappropriate conduct by either side takes place. Any irregularities will be immediately acted upon and reported to IBM and Kasparov. The members of the Appeals Board will be agreeable to both sides.
