The effort of your “detective group” was wonderful, and all but very few bridge players will always be grateful for that.

But it also makes me wonder. Many of the codes that got cracked were extremely simplistic. Moreover, future cheats could always look at these efforts and get a fairly good sense of how complex their methods in order not to get caught. On the other hand, the bridge interpol will have access to many more videos in the future; but then, the interpol doesn't have 10 clones of Brad Moss and Ish Del'Monte to comb through 10 times as many videos.

You must have thought about this much more. Are you optimistic of catching/deterring future sophisticated cheats?

Playing in a club game, the biggest advantage from “1 = could be short” is the inevitable discussion by the opponents “Ok, let's play 2 = natural and 2 = Michaels over that”, with promptly exactly one of them forgetting a few minutes later. I am almost tempted to skip announcing our system against non-experts at the beginning of the round in order to protect them…

What a coincidence - Han's guess exactly matches Balicki's distribution!

They were about 963 (ok I am exaggerating) The Bridge World editorials about sportsmanlike dumping while F-N and B-Z were winning event after event. Many others about aspects of the law that are obscure, at least when compared to Law 73B. Don't you think they could have used their platform better than that?

The hypothesis is “Large gap signals something, one possibility that they have a void in the opponent's suit in a competitive auction”. I.e. if they have a void in the opponent's suit, they will bid with a wide gap; but not the converse. (And note that this fits well with Gonzalo's hypothesis.)

If these seven hands are really all the examples of having a void in their suit in a competitive auction, then this sample is more meaningful than people may realize. (Ball-park estimate: if 1/3 of their bids have a large gap, then the chance of this happening by coincidence is about 1:2000.)

I also thought declarer might go down if West plays a low heart instead of A - he'd play East for a doubleton and protect against Jx behind. But I also understand why West did play the A - he also played partner for a doubleton (3=2=3=5), in which case he has to play A and let partner ruff the third heart.

You can also skip forward and backward by 5 seconds with the cursor keys. (As usual with web browsers this only works when the right part of the window has keyboard focus, i.e. it only works sometimes and I have no idea why and when.)

And Zimmermann was in on the joke? Or was Balicki playing a joke on one of the biggest bridge sponsors, too?

Come on Josh. It's not fair he can play bridge that well _and_ use the internets.

Of course it “should”, but I presume the WBF doesn't think it has the authority to do that (only the EBL could withdraw them, or the Polish team voluntarily of course).

General conditions of contest, 3.8:

Credentials Committee
Pursuant to the By-Laws of the WBF, the President has appointed a Credentials Committee, whose functions shall be (subject to these Conditions):
a) to determine all questions relating to the rights and eligibility of players and non-playing captains whose names have been submitted by an NBO for invitation to compete in a World Bridge Championship
b) in its discretion, to refuse to invite any player or non-playing captain whose name has been submitted for invitation by an NBO, as aforesaid, to participate in a World Bridge Championship. In any such case of refusal, no reason shall be given by the Credentials Committee.

So don't expect the WBF to disqualify a team, nor to announce any reasons for this decision.

I wonder whether that's how F-N started. E.g. lead a singleton = I want partner to win the trick = lead vertically.

“Why do no other top pairs play fantunes twos?” David, I can't resist pointing out that the 2M openings by Wladow-Elinescu were very similar - 10-14, 6M or 5+M/4+m (except when non-vuln against vuln).
