Bridge Winners Wins Challenge Match
Beer or no beer, Greg and Adam put up some nice results.
Is this hand worth a negative double?
Fitted jumps are useful useful when they allows partner to recognize minimal wastage. This is a very dull opener: KJx, xxx, Jxx, AQJx But if the auction is: 1 -- (1) -- 2 (fitted) -- ? You now know immediately not to stop bidding below 5.
Is this hand worth a negative double?
Eric, Your comment hit the trifecta today: * It is pedantic * It is irrelevant * It is not correct
Is this hand worth a negative double?

Henry Bethe's bidding problem: 54 A8 T742 AT975
The suit makes a difference. If you held a heart suit, your hand would be worth a game invitation so you would use a sequence that shows your values. Given that you hold clubs, game chances are remote. With poor game chances, you can afford to bid a wide-ranging 3 ...
Full Disclosure During a Simul-Forget
You explain the failure to alert and do not explain your own misbid. After the hand, a director can adjust the score if he judges that the opponents were damaged by your actions. Players are supposed to follow the law like automatons and allow directors to make correction in any ...
