I am writing a book on bridge and statistics (I expect it to be a huge seller!). Most of the book is already written. Some of the answers OP wants are already in the book. I'll add answers to some of the other questions from this post.

BS+ knows exactly when each team's assignment is posted. It knows exactly when the last team assignment for a round is posted. That's the official start of the round per ACBL. Because players enter scores, it knows exactly when the score is reported for that round.

BS+ can report the late plays down to the second.

Enforcing the late plays is up to the DIC, not me.

I suspect that for the first Swiss, they will be generous - new technology, new ways of entering scores, players have to learn etc. etc.

But for the second session of a two session Swiss, all captains should be familiar with the process.

Finding a DIC willing to enforce the ACBL rules for late plays is hard. We'll see. Sadly in D7, we have some board members that believe that they are fast players; but are actually slow players because it's always the other team's fault. Every time. First time TDs enforced the late plays, some vocal D7 board members complained.

Running the events and making those decisions is up to DIC/TDs/D7/tournament chair, not me. Just letting you know that the software has the ability to track late plays and enforce penalties.

BS+ also does early assignment; similar to ACBLscore. ACBL won't provide their early assignment algorithm, so BS+ has its own, which has worked well for 3+ years.

Running all KO and all Swiss, including Bracketed (Round Robin) Swiss.

BS+ has logging so it knows the exact start/end time and can be queried after the event. D7 has been doing manual metrics at tournaments without Bridgescore+ so we can compare

At Gatlinburg last year, the morning Swiss was Bridgescore+; the equivalent number of teams were in the evening Swiss run by ACBLscore. Morning sessions finished 25 minutes quicker than evening sessions - same number of teams/boards/rounds etc. See http://www.bridgescoreplus.com/status/180422-gatlinburg.html for details from Gatlinburg last year.

I suspect hands where there are more gaps in each suit is computationally harder.

For example, if N has AQ107, then as soon as the J is played the 10 and Q are computationally equivalent.

Computing power doubles approximately every two years (Moore's Law). Computers are 8x faster than 6 years ago. 16x from 8 years ago etc. The use of GPUs instead of CPUs can solve some problems (including double dummy analysis) orders of magnitude faster. For example, a CPU may have 4 cores, a GPU 1024. GPUs are perfect for DDA.

So to answer one of your questions: computing power has increased to cancel out any effects of finding slightly more complicated DF searches.

Kit: If you try that in an ACBL event, then the CoC will apply:

“The refusal of a player, pair or team in an ACBL event to play against another player, pair or team shall require their disqualification, from further participation in the event and the forfeiture of any masterpoints earned by the player, pairs or team in the event.”

At the moment there are 40+ comments. Some of the highlights:

Roy Welland: Awesome! Erik, each time you see me for the rest of the year, please come over and collect your free beer, wine, or Champagne!

Andrew Robson: Two ways to win. (1) More time to drink beer. (2) Sending a strong, brilliant message to the bridge world.

Nikolas Bausback: First of all: I admire both players for their couragous decision! But I do not think that's the way to go. With boycotting we hurt first ourself, secondly the organizers and in the whole the Bridgesport. In my opinion the right way is to cut them, is not to communicate with them. We have to show them that we do not want them? First and foremost, the organizers and officials are in demand. And of course we players. The officials have to do everything that these ones can not get to tournaments. It should not be like in Milan, where you could see key officials in small talk with them.
#saynotocheats

Sabine Auken: In certain cases federations may not have a choice. They may be bound by court rulings and not be allowed to exclude anyone from participating in their events. Private organizers do have a choice. They don't have to let everyone play. I am all for boycotting events, when the organizer has a choice and decides to let convicted cheaters, who have sued their way back into the game, play. Roy and I will not participate in such events.

Roy Welland: I agree with Sabine, if an organizer has no option to prevent cheaters from entering, they cannot be blamed, but if a tournament *elects* to allow cheaters to participate, they will be *permanently* boycotted by me personally, and hopefully by all others who love the game.
As for your proposed strategy, I'm pretty sure these players do not care about communicating with others. They have watched themselves cheating like dogs on video, but still are coming back to play.
Do you really think they have any shame?

Jose Damiani: If all the players west leaving then the federation or
the club would not have other choice than refuse the
entry of the unwelcome people who are making trouble to the general public interest and should go home and stay forever

Tonje Brogeland: I don’t have a Facebook-account, but have borrowed my wife’s for a comment: When organizers are unable or unwilling to keep cheats away from tournaments, players need to band together in order to get change. Well done to Silla and Morten Olsen for leading by example. If more players followed suit, the organizers would have to think twice before letting cheats play. For cheats to get a second chance, they must a) admit they cheated and b) serve their time (ban). No exception.

Sabine's Facebook post (referenced above) reads:

Big congrats to Silla Diktatore (Erik Sælensminde) and his partner Morten Olsen for fighting for the integrity of our game and leaving the Barcelona tournament after 10 boards when they became aware of the participant list. Well done!

Pedantry: “1 in a million is 0.00001% ”.
1 in a million is 0.000001 or 0.0001%; it is not “0.00001%”, that is 1 in ten million.

Nope. I cited the correct minutes.

After the complaints were made, ACBL were forced to change their By Laws. Otherwise, why change the By Laws?

Heth's report did not address my main complaint. For an obvious reason.

Heth's report applied the criteria AFTER the By Laws change; not before the By Laws change. In other words, she applied the post July 2018 rules to the earlier transactions.

Also, IANAL but I have a good one.

Remind me towards the end of the year. There's more to this story. I'll post it then. It will explain the background a little more.

You are welcome to check the Conflict of Interest policy in effect at the time and form your own unbiased opinion.

I prefer Parallels over Boot camp for the same reason. You are more likely to get viruses from the PC environment than the Mac environment.

If you run Parallels - AND have a large enough disk - then you can create a known safe copy of Windows 7 (or whatever version you use). You then clone this (a Parallels term for making a copy). You then work in and make updates to the cloned copy. If… you ever get a virus/problem… then you have a known safe copy to go back to. Of course, you will clone the known safe copy before working on it. This gives you some revision control. Look at the problems with ACBLscore and Windows 10. If you were running on a Mac with Parallels then you could very easily roll back to the older Windows 10 that works with ACBLscore. This is how I operate my environment for running Bridgemates with Bridgescore+.

Parallels is a Mac applications that runs in the Mac OS environment.

Bridgemates work independently of the scoring software. They are not made to run only with ACBLscore.

Personally, I prefer Parallels to Boot Camp because I am still in the Mac OS environment.

Nothing in OP about ACBL or ACBLscore.

This is not taking anything away from what you are doing at your Club.

Ask the ACBL!

From the horse's mouth: See
http://web2.acbl.org/documentLibrary/about/PhillyMotions.pdf

“ITEM 181-28: UPDATED CONFLICT OF INTEREST POLICY
Purpose: Revise ACBL’s Conflict of Interest Policy to comply with New York law.”

All this came about from a complaint to ACBL. They were not in compliance with NY Law. Ask ACBL league counsel for the specific law. They had not been in compliance for a few years.

@Steve: The specific complaints I filed were not addressed in that report.

I run Windows 7 on Parallels on MAC and Bridgemate in that environment when using Bridgemates for Bridgescore+. Make sure you set the correct control of the USB port in Parallels.

It's on the list of things to do….. but on the back burner.
Right now my focus is on Gatlinburg (+ a couple of prior regionals) and everything I want to see done there.
Looks like Gatlinburg will run all team events using Bridgescore+.
Should save the tournament thousands of dollars in TD session fees, finish team events 20-25 minutes faster, but got to make sure all the training/documentation/testing is done.

In the research I have done, I do not see the data to back Chris W's claim.

@Mike: “Until we have a new scoring program that can easily accommodate setting up team events, I see no future in advocating for change.”

Bridgescore+ is a new scoring program that easily accommodate setting up team events.

@Keith: “ACBL has worked with CG for years ”

If this has been going on for years, this was in violation of NY State Law and also the ACBL By Laws and the ACBL Conflict of Interest policy for District Directors that were in place up to August 2018.
