I like the BiddingBox feature of monthly ACBL bulletin, where you can practice bidding on 8 carefully selected hands, and compare results with 2 pairs of guest/expert players, and results scored by Bob Wolff. The only trouble is that it's all on paper, and you need to remember all 8 bidding results and then go back to check your contract against the actual hands. Is there a way we can integrate this feature with BBO? Of the top of my head, you can open a bidding room, and load those pre-dealt hands, go through bidding, and having both hands pop-up at the end, so both can see the actually hands and discuss them, as well as compare your results with other pairs. This would be a great convenience feature. I would be willing to pay for this feature, and I think others would too. I would also think ACBL love to have some additional revenue? Notrump0
