I like those BridgeTabs but I'd make some comments.
I have seen them in use in two clubs and in both cases the chosen hardware was a Lenovo tablet.
The button to turn these tablets on is by the side but round at the back of the tablet. I would prefer a device that could be activated by the sort of home button that you see on Samsung and Apple tablets - on the front so that the BridgeTab can be turned on and you enter the contract etc without having to use two hands to raise the device and operate the switch.
Beyond that, I would like to see a couple of features added to the devices. These both centre around timing.
It would be great to get some sense of timing from the BridgeTab. A setting from the TD to tell the BridgeTabs the amount of time to be allowed for each round would allow the devices to give a nudge to individual tables to let players know if they are lagging on time.
Further to that, for games in which the BridgeTab is set to provide information such as running scores etc the ability to see those should be blocked when a table is behind schedule. I know that is really only relevant to those club games at which the BridgeTabs are set to display such information but it would certainly give a hurry up to club players who are tempted to spend a lot of time looking at the travellers etc.

Another doubled small slam from the weekend.

Holding Qxxxx x x KQJxxx partner and I hoisted us up to 6C and we got a (deserved) double from LHO - a member of the NZ youth development squad.

I figured that I had chances but did not redouble.

The slam would have been off one had LHO started off with one of his three major suit top cards but he was greedy for two or three down and started with his singleton diamond.

Dummy tabled J Kxx AKQxx Axxx.

Win the Ace and draw trumps in 2 rounds ending in dummy.

Cash another top diamond for a heart discard and realize that the 6-1 diamond break means that there is no chance of a discard on a long diamond.

I am left with:

J Kxx Qxx xx
Qxxxx - - Jxxx

I have 4 trumps, two Spade ruffs and the Diamond Q but in total that is just 11 tricks. Looks like I am one short but there is still hope. Queen of Diamonds for a Spade away, a Diamond ruff and a Spade towards the stiff Jack.

LHO is in with a top Spade but now has to lead away from the Spade King or the Heart Ace and I am home.

Not redoubling was the right move as it would have curbed LHO's ambitions to getting me one down and he would most likely have started with the top Spade.

Just last night, partner opened 5D and I held AQT6 AT72 KQT K2. RHO doubled and I bid 6D which was doubled on my left and I redoubled when it came back to me.
We thought that plus 1380 should have been a good result but team mates brought back -1700.
What did partner have for her 5D opening? I could describe her hand as 5 5 in the majors. But I should add that the fives were both singletons and she also had two small clubs to go with 9 diamonds to the AJ.

Germany has a constitution and every person and organisation in the country is required to act in accordance with the constitution. The possibility of rehabilitation and redemption is established in the German constitution and the court seems to have found that the 10 year ban for two elderly men went beyond what the constitution would countenance.
Beyond that, European human rights law would also have a bearing on any long bans.

Thanks Paul
72B3 comes into play here with a second revoke. Is there a penalty for that?

John Portwood's description is not really correct. The removal of double jeopardy (through the 2003 criminal justice act) only applied to the most serious crimes and a second prosecution could only proceed if the public prosecutors could convince the court of appeal that they had substantive new evidence. That is a high barrier and double jeopardy prosecutions are a rare occurrence.
Even before the 2003 act, double jeopardy protection could be waived in certain circumstances.

I have now used this in three tournaments.
Seven sessions of pairs, almost two hundred deals and around seventy different opposing pairs.
I do my best to shield my scorecard while writing and it is always turned over when not being updated.
During play two people have asked what the code means.
If the ethics of your opponents are similar, at least 3% of pairs are trying to look at your personal scorecard.
I say at least because some others will probably have looked and kept quiet.
As for whether of not it is distracting for me to do this, I won two of those seven sessions and picked up a 2nd as well. One win was in a very strong field (including two current world champs) and I scored almost 68%. Perhaps I should conclude that this is worth a 15% boost to my score as opponents look at my scorecard and expend too much mental effort trying to decode my entries!

I write it as a 4 bit binary value. The seems to be enough as it will go up to +7 which cannot happen and -8 which should not happen.

The big difference is that bridge does not depend of tens of thousands of spectators buying tickets or tens of millions paying for TV coverage.

Non sporting results have damaged other competitions in the past by reducing subsequent tick sales or viewer numbers.

In France, the top football division (at least) attempts to avoid such issues with seeding such that, for example, the previous year's champions get to play against the weakest newly promoted team in the last day of the competition.

Last night, I played in the first session of the last duplicate tournament of the year down here in NZ.

Individual score-sheets were provided - they carried a message from the event sponsor on the reverse.

I was not aware of anyone leaving their sheet exposed though I was not actually paying attention to that. Nobody left so much as an empty coffee cup at the table either.

I kept my scores. I wrote the contract level in binary and I translated the suits (not NT) into French and then wrote down the first letter of the suit or NT transliterated into Cyrillic. Then I wrote the result, expressed as +1, -2 etc in two's complement binary. At the end of the session, I converted that into plain text scores for checking with my results.

It took no extra effort to write down like that and by the end I was thinking of the suits in French anyway.

Even with knowledge of my little code, I doubt that many players would be able to get much help from a glance at my sheet.

Silly I know, but why not and if an opp ever comments on the code, I will know that they are peeping.

Both of the clubs of which I am a member maintain lists of phone numbers and email addresses. One club publishes these in the yearbook. The other has a password protected list on the web.
Both work well with no abuses of which I am aware.

Echo from here too and I'll look forward to playing against you in the new year Alan. Will you be playing in any tournaments before the Auckland club restarts?

Folks need to pay more attention to what Tom just said.
If you have cracked the hands then the amount of information that you must absorb to get a crushing advantage is tiny.

I had a look at the big deal design when this first came up. I have not examined the code for implementation weaknesses but the design is sound.
A computer system that could break the discredited acbl system in a minute would require a couple of million years to do the same to BigDeal.
That figure is not an arm waving approximation - rather it is a calculation based on the amount of information that you do not have when trying to crack big deal because of its design.
I do not claim to be a world class crypto expert but I do work in the general field for a living and have done so for many years.

Hooking something like this up with a wireless network could be done. There are businesses out there which do this all the time for trade shows, sports events, conferences etc. It is not cheap and if you cut corners you get burned but with the right suppliers it is routine.
You would not need such a setup for this system though. You could equip each tablet with a usb/ethernet adaptor and hook everything up with standard cabling. That would save a lot of money and reduce the skill level requiired of the people setting up the system in a new venue.

I indicated the table and the director mentioned the issue to the table and reminded them to be quiet.
