The study found this was true for expert bridge players but not for expert chess players. While I think bridge and chess require roughly similar amounts of intellectual effort bridge has many more facets. For instance, chess players do not have to deal with hidden information. Bridge players have much experience evaluating multiple possibilities where evidence points in different directions. We also get rapid feedback on the accuracy of our predictions.

An alternative to stifling discussion, Richard, would be to not read the thread.

Instead, we could try to find a bridge connection for every post, but that could get ugly too!

You may well. You didn't cite any evidence, though. Most of the public discussion of the topic has been remarkably evidence-free, or has centered around points that are not only of limited relevance but have been demonstrated to be false, such as the so-called hockey stick or the imaginary decline of polar bear populations.

Did just that, to no avail. Perhaps it's a scam site. More likely it's running on auto-pilot because the proprietor thought he could turn a four-hour work week into a zero-hour work week.

Thanks for posting! I'm always impressed by how many points you can find in a deal that appears straightforward at first.

North's 3 at the other table seems dangerous. 2 would be normal and it looks as though it will make here, even on a trump lead. Declarer can work out that he has enough winners without the diamond hook.

How is this a problem, Ray? I ask with one KC and discover that partner has 1 or 4. I sign off in five, hoping that we make it if partner has only one. When he has four he bids on, showing the trump queen and/or a King in case we have a grand. Kit said as much. The KC responder can bid on in confidence since he knows we're not off two key cards.

The new laws have been approved by the WBF Executive Council and can be found here:

Thanks to everyone who chimed in! To my mind the lawbook is substantially improved as a result.

Thanks, Ed! Alas, the rolcogames.com SSH certificate has expired. I ran a Google search and found some 10-second timers on Alibaba, but most vendors have a minimum order size of 500. One had a minimum order of a single unit. I tried to send an inquiry, proposing to purchase a dozen, but get an error from the Alibaba site. Technology is grand when it works…

Link for the timers, please! Some opponents will find it obnoxious, but I know from experience that TDs will feel put upon if I call the TD every time LHO fails to wait after my skip.

I agree with Randy and Nigel. Some years ago I submitted a proposal to put their suggestion back into effect:

I don't think TD's have a reasonable chance of enforcing the regulation unless they have an objective means of determining whether a call was too fast. Players, recognizing this, seldom call the TD under the current regulation. As a result, there is much unnecessary suspicion and ill-will.

JoAnn, as National Appeals Committee members you and I have more experience than most in dealing with UI issues. It's difficult to do well, often impossible to do fairly. In some cases it's unavoidable, but I am all for keeping the issue from arising whenever we can.

At the C&C meeting, one of the committee members expressed a special concern that the Stop card discourages newcomers. I don't expect it does, for a few reasons, including that no TD would enforce it against them, but it got me thinking. How will the new, no Stop card, no announcement, but mandatory 10-second pause affect newcomers? I can only think it will tend to discomfit them and drive some away. Imagine playing in your first open duplicate. Your RHO opens 3H. You don't have anything special so you pass. “Director!” What happened? Why? And why were you expected to do something unusual with no warning? I, for one, would find that confusing and intimidating.

I championed my proposal at the C&C committee this morning. They again voted to recommend to the BOD that the ACBL eliminate Stop cards. In Orlando the committee vote was unanimous. This time the margin was 5-3, so apparently my proposal had some effect.

I don't like to see such a sweeping change made without a strong consensus. Does anyone want to take up the battle?

I mentioned Craig's concern at the Board of Governors' meeting on Sunday and forwarded his note to the HOF committee and the ACBL president. It sounds as though they intend to attempt to address the issue.

I also note that Kenneth Arrow passed away last month.

A TD friend also told me that there are no pauses after skip bids in Australia. According to him, if a player thinks for a few seconds after a skip and the opponents call the director, the director will take a poll and adjust the score if his partner has a logical alternative. This is not the way I want to play the game. We are all better off with an enforced pause after an unexpected action by RHO.

I do agree that the skip bid regulation is poorly enforced in the ACBL. That's no reason to scrap it – there are alternatives! Poor enforcement could be due in part to a poor regulation. Not only is the one we have ineffective compared to the WBF's procedure, it makes no grammatical sense:

“The Skip-Bid Warning is given by displaying the stop card, making a call and then returning the stop card to the bidding box. Following the Skip Bid Warning, LHO is obligated to wait approximately 10 seconds (while giving the appearance of studying his hand and not in excess time to determine a choice of bids) before making a call.”

I don't know where it was invented, but it was ACBL policy for several years.
