If I’ve understood this post correctly, I can leave sit outs in place for a BBO clocked pairs tournament, with an odd number of pairs, using either a Mitchell or Howell movement. I am unclear about what the TD will need to do, playing two board rounds. Presumably, cards for the the first board will be dealt at the sit out table at the beginning of each round. When the round clock times out, the first board will be terminated as incomplete, and the second board won’t be started. Will the TD be asked to provide a score for both boards, or just the first, or neither? Assuming the TD assigns average scores to incomplete and unplayed boards, will the tournament results show the pair Sit Out and Sit Out as scoring 50% on all boards, and hence 50% as a final result?
