"Handling of unplayed games To avoid improper influence of unplayed games on the ranking these games shall be counted as follows : Independently of the result of an unplayed game (win by Bye, win or loss by forfeit, no game because the player has withdrawn or was absent for some round(s)) for reasons of tiebreak, the result shall be counted as a Draw against the player himself. This will have no influence on the Sum of Progressive Score or Koya System. In these Systems only the result counts." That said however, the following should be noted: In the FIDE Tournament Regulations FIDE dont specifically state what tie break system to use but simply point out a number of possible tie-break methods. However in all of the FIDE tournaments actually mentioned by name in the FIDE Handbook eg Zonal tournaments or world Junior, world seniors to name just 3, the tie break method is as follows: For Swiss tournaments where the players involved have all played only against rated opponents, after eliminating the lowest rated opponent, find the sum of opponents' ratings. The highest total wins. If still tied, eliminate the rating of the next lowest rated opponent(s) until a decision is possible. For other Swiss tournaments, the sum of progressive scores. The highest total wins. If still tied, deduct the first round score, and if necessary the second round and so on. I would think that for computer chess the sum of progressive scores method would be the most appropriate. The sum of progressive scores method is calculated by summing the players progressive score at the end of each round. I'll leave it to you to do the calculation :) Regards, Bill
