Slow play - boards not played
What are the rules (if any) on scores to be awarded if a board is taken away due to slow play? In one club, the TD awards 40% to both pairs, saying 'that is club policy'. This causes some dissatisfaction especially when one pair has been kept waiting 5-10 minutes by the other pair arriving late. The TD's reply is 'you just have to speed up'. At all other clubs I know, it is 50-50 or 60-40 if one pair is clearly at fault. This is an EBU affiliated club, in the NGS scheme etc. Can the club decide what to award?
