Stuffed by UI
Also, when reading Law 50E1, it is not altogether clear that inferences from the penalty card are UI: [i]Information derived from a penalty card and the requirements for playing that penalty card are authorized for all players for as long as the penalty card remains on the table.[/i]
Stuffed by UI
Who had UI?
Is this a way to run an organization?
When the first Danish Bridge Festival was held in 2005, the Danish Open teams tournament was introduced. The ambition was that it would eventually turn into something similar to the Chairman's Cup in Sweden. The number of participating teams was usually around 18-20 teams. We got the feedback that ...
2D weak one major
I also used to play the 4/ responses allowing responder to make either partner declarer, but found that the opponents are too happy about the opportunity to do something useful with our bids. 4 as P/C seems to occur far more frequently than the long heart ...
Another Un Understandable Appeal at the USBC USA2 Final?
[i]Just another example that less experienced players are better off playing a hand to a clear conclusion rather than claiming when it only seems to be clear, but isn't.[/i] My general advice is to play the hand to a clear conclusion rather than claiming when it only ...
Legal: AI or UI?
In the present case, it is evident to North that hearts are not trump when he is not allowed to lead to the next trick :-)
Legal: AI or UI?
North's statement that he believed that he ruffed with the 8 is UI to South. The fact that they are playing notrump is AI to North. We cannot force him to continue playing a heart contract once we have to tell him that he actually discarded.
Opening pass out of turn when pard is the first to bid
Bryan, I wonder whether you are asking a more general question along the lines of "Suppose N-S use UI to get to a ridiculous contract, but due to a subsequent fluke they get a good result. Should the score be adjusted?" Just in case you do :) this is answered by ...
Viking Club 1M-1NT question
Michael Askgaard and Kasper Konow of the Danish national team play the Viking Precision Club with a modified version of the 2-level responses: 2: Signoff with 5+, or any invitational hand without 3-card support. Thus, 1M-2-2-2M shows a balanced invitational hand with a doubleton for partner ...
Opening pass out of turn when pard is the first to bid
Obviously guessing because I don't know the hands, but it seems that without the 1NT bid, which was illegal due to UI, the bidding would probably have gone 1-4 instead. So adjusting to 4 making whatever could well be reasonable, for both sides. Then, you might ...
