So, simple solution, why not just have two versions of the tournament, one with 8 and one with 16 boards? The Robot Rewards are fun enough, but there is a reason that we gravitate to matchpoints rather than kitchen bridge. 'sides there is a completely different strategy to the rewards game, while the same people seem to win consistently so it clearly is related to ability and skill, it really only proves that you can adapt to your partner always having a worse hand and knowing how to bid accordingly. Sounds like some others might be interested in the concept of a greater number of boards, why not try one of these on the hour to see how popular the idea is?
