I've started playing robot duplicate games routinely. I think the robot games offer a lot of potential for players to improve their game. However, the "best hand" principle makes the duplicate games into a novelty, as opposed to Real Bridge. I would like to request that the people who run BBO start offering "random hand" robot duplicate games (currently only the "Robot Reward" games are run in the random hand format). The reason I would prefer random hand games is that it would give me an opportunity to develop my game in a more comprehensive manner. In real bridge, you have to defend a lot more hands -- I want to work on my defense. In real bridge, auctions are much more likely to be competitive -- I want to work on my competitive bidding. In short, I want to work on all aspects of my bridge game, and the "best hand" format just isn't doing it for me. I really enjoy using BBO and playing the robot games. I hope to see more "random hand" robot games offered in the near future!
