This is the BAM movement.

@Mike, I just realized you are from D4. I'm aware of your area running Swiss using duplicated boards. Now you could even using Bridgemate for it so players could eventually see their results on each board just like pair game. PM me if you want to learn more.

There are other districts and club that play regular Swiss team with pre-duplicated boards in a similar way. For each round every team play the same set of boards (i.e. 1-6), you could play 2 boards per table and just the boards twice in whatever way convenient.

Could you clarify your board movement? I think it would make sense for A1-A2-A3 to be a group and rotate boards 1-6 among them for round 1. Similarly B1-B2-B3 for 7-12 and C1-C2-C3 for 13-18. Then you rotate for board sets A<-B<-C<-A for round 2.

6K Soloway makes more sense since the seeding for 6K event currently does not reflect team's real strength.

Natural response transfer style. For unpassed hand 1 is negative. For passed hand, transfer to majors only, all other hands bid 1.

Here is my 4th seat opening and I also use it for 3rd seat opening to save my memory load.

2: Precision 2 open;
2/2/2: 11-13 HCP, 6 card suit;
The NT ladder is
12-14: open 1NT;
15-17: open 1 then rebid 1NT;
18-19: open 1 then rebid 1NT;
20-21: open 2NT;

One level open 1/1/1 could be up to 19 HCP. All other hands open 1. This leads 1 to have 3 types of hands:
1) strong two;
2) balanced 15-17;
3) a hand with club suit that is better than 2 open;
After 1 open, responder uses transfer responses. Opener has a special bid to indicate if he has a strong two opening.

I don't like to open a sub-minimum hand in 4th seat because it gives opponent a 2nd chance. Most of players don't have an opening in 1st and 2nd seat for two suited hands. If you open they get another chance. If your side has a fit, their side is also likely to have a fit. If you don't have , this is dangerous.

I suggest a penalty carryover. They will be applied to both teams when they play the same event next time.

With only 18 tricks, there are 3 possibilities:
1. NS could make 3 and EW could make 3;
2. NS could make 4 and EW 3 would be -1;
3. EW could make 4 and NS could only make 2.
In case 1, NS bid 4 would get -50 but pass would result in -140.
In case 2, NS bid 4 get 130 but pass only get 50.
Case 3 is a danger because 4 could be doubled or it could push EW to game. However with NS high card holding (AKs) this is unlikely.
If NS judge this correctly bid 4 is always a winner in case 1 and 2.

For EW it would be different. In case 1, bid 4 could result in -50 instead of pass 4 for +50. In case 2, bid 4 would be -2 for -100 instead of pass for -130, but it ran a danger of being doubled. Only case 3 could be winner. So EW does need to judge it correctly and it is a tough decision. If there were 19 total tricks, bid 4 over 4 would always be a winner.

There is a food court in Bally's that is not listed in ACBL restaurant guide. It has Sbarro, Subway and 4-5 other stores offered different type of food with reasonable price. It is just of the map from ACBL guide. You could walk through Paris LV to get into Bally's, then turn right and go downstairs. The food court is at the end of it. If you enter Bally's from front door, go straight to pass the whole casino and go downstairs.

I agree 4 is correct bid given 3 could make.

David, Planet Hollywood area has a lot of different restaurants. It is right across the street and you could walk from skybridge. Look for Miracle Mile Shops.

This is quite true. Money is a good incentive for players who never played NABC to attend. I won NAP and GNT flight C in 2011 and attended NABC first time. After that I have been a regular NABC attendee even I only won GNT B once that paid part of cost. There are 42 GNT B teams but only 26 C teams this time. I would guess there could be more C teams but their district did not want to pay the 2nd C team so they did not come.

I think AI learning would be critical if it is going to beat human eventually. The problem now is we don't have a very good definition of what bidding means. I don't like current BBO bot because it often made a bid but don't have that hand. I could not trust what it bids.

In my early comment I suggest we needs some kind of standard language to describe bidding system. Players should be able to construct his own bidding system and feed to the program, Bot could use AI learning to train itself on a system. Eventually Bot might invent its own system.

In past few years I have been testing a bidding system that varies opening/response by position, ideally it should also vary by vulnerability. However that would be really complicated for human players. However it is not a problem for Bot. In this sense I think Bot would eventually beat human, just like it did in Chess and Go.

Craig, you could look at my post for rating system below.
https://bridgewinners.com/article/view/an-elo-rating-system-for-bridge/

KO and Swiss team could also be rated with same methodology. However ACBLScore currently do not record IMP wins for KO games. So these game could not be rated for IMP rating. For Swiss teams it lacks of pair information, however with Bridgemate supports to team game now, it is possible for future team games to be rated.

I think the priority at present is data definition. AI, machine learning has improved a lot and they could eventually outplay human like they did in chess and go. What we don't have today is the meaning of a bid, a card played in certain defined data.

BBO used to have a way to allow player's to define his/her own bidding system, but has stopped to support it in the recent release. I would take that framework to create a new standard in describing bidding data. BOT has to be able to use these standard to figure out each player's bid means.

I've contacted ACBL and this should be fixed soon.

It looks like the problems is only with Bracket 1. Other brackets are fine. However with multiple brackets exist the top bracket definitely could not be only 4 teams.
