I am going to fine declarer for taking a clearly misleading action. I do not care whether he is required to show his cards in the general case, and I think it irrelevant to this case. If a declarer does not show his cards out of casualness, that is one thing - though I think it is sometimes rude - but if he does not show his cards where it can mislead, that is totally different. So, for the purposes of this particular problem, I do not care, and I do not think anyone else should care whether declarer is required to show his cards with a normal claim.
If the Laws do not require him to show his cards in general, then I can give him a PP for inconveniencing other contestants, or I can give him a DP for upsetting other contestants. Whether I should do the latter is for another thread.
We have had a number of threads recently where someone changes the situation from the original post, then gives the answer. It seems unhelpful, and it is certainly unnecessary: within reason, there is no limit to the number of threads any individual may start, so if anyone wishes to discuss a different matter,
please start a new thread.
Should we do anything about a claimer in a general case who does not show his hand? That is a good question, and if anyone wants to discuss it, please start a new thread.
On Monday I go to Reykjavik, Iceland, and the following weekend to San Remo, Italy [via Gatwick and Nice]. I shall take my computer, of course, but if I have no internet access I shall be missing for two weeks. I am happy to see anyone from this forum in either place. If I do have internet access, anyone who wishes to communicate with me should use my hotmail account [try "b l u e j a k 6 6 6" followed by hotmail and then com and use your intelligence
] or text me.
