In the first round, starting at 10 a.m. on Sept.1st, the United States team will have White on the odd-numbered boards (1,3,5, 7 and 9). In the second round, starting at 10 a.m. on Sept. 3rd, the pairings will remain the same as in the first round but the Soviet team will have White on the odd-numbered boards, All games will be played to a finish.
   In both New York and Moscow, an official of the opposing team will be present to check on the satisfactory operation of the rules and procedures which have been agreed on for the match. The chief duty of these officials will be to observe the progress of the time Control, which has been set at forty moves in the first two and a half hours, and sixteen moves thereafter. The method of recording the time consumed in a match of this kind is of course more complicated than In an ordinary game where both players are at the same table, According to present arrangements, this will work out as follows: the American players who have the White pieces will have their clocks started by all official as soon as the time for beginning play arrives, When the player has made his move, be will stop his clock, record his move on the score-sheet and then on a slip of paper. He will hand this slip to the teller, who will process it for censorship and transmission. When the reply to this move has come from Moscow, it will be recorded. confirmed, made by an official at the proper table, and the player's clock will again be started. On the boards where the American players have the Black pieces, their clocks will not start until they have received the first move of their opponents.  At agreed intervals, the cumulative amount of time consumed on every board will be radioed to the opposing team.
     As will be seen, the process of making, recording and transmitting a move involves a considerable amount of labor and precision. Each move passes through the hands of several people, correspondingly magnifying the possibilities of mistake and confusion. To reduce this difficulty to a minimum, all the moves will be translated into a special system, known as the Udeman code. Each square is identified by it two-letter syllable, and moves are indicated by giving the two letters representing the square from which the piece has moved, followed by the two letters of the square to which it has been moved.
   Both sides have agreed that Mr. Derbyshire,, head of the British Chess Federation, is to be the official referee to decide any disputes which may possibly arise in the course of play. Thus all three great United Nations are represented in the match.
