Can you have UI generated solely through your own actions?
Ed, The fact that you broke tempo is AI to you. The inferences about how your BIT effects partner's choices is UI. Example: if you are thinking whether to bid or pass, and realize that you broke tempo, you are allowed to choose bidding even if your final analysis ...
Is an adjustment warranted?
Partner's alert is UI. Partner's 3 bid is AI. You need to judge if the UI affects the player's interpretation of the 3 bid. If you judge that without the alert the player might interpret the 3 bid as a "sign off" then you ...
Alert question
The second option is the closest but you should only "announce after the auction" if your side end up declaring.
Which meaning is alertable?
Appologies, 2m = Michaels showing both Majors. Updated now.
How would you rule ?
Although the BIT suggest that North's 4 bid was not pure, I don't believe that South has a Logical Alternative to Passing 6. If North wanted to offer a choice between Diamonds and Hearts they could have used 5 or 5NT or 6 depending ...
Correct explanation of 4NT
Alex got it right in the first comment ("Asks for the number of Key Cards"). Many of the other responses, while better than "Blackwood" are also inappropriate. Names of conventions such as "Roman Key Cards" or "14-30" or the likes are NEVER a proper answer when the opponents ask for ...
Do YOU play any of the "Worst Conventions?"
All these polls are pretty useless as it all depends on how the convention is structured and the entire bidding system. Few examples: Having the agreement that a 4 bid is always "Gerber" is terrible but agreeing that a direct jump to 4 over a Natural 1NT or ...
King Please or Thank you?
Michael, this usually happens when dummy comes down and declarer realizes s/he has a lot of work to do. They start thinking about the complicated hand and at some point take a mental break to thank partner. They then resume thinking about the hand until they are ready to ...
King Please or Thank you?
I have observed this type of delayed "Thank you" many times at high levels.
King Please or Thank you?
I listened to the audio many times using high end head set and can say with about 95% certainty that declarer said "Thank you". Then I watched the video on a 5K screen and that enforced my belief that declarer said "Thank you" since both declarer and dummy did not ...
