Three hearts is a weak jump overcall. There was no alert of the double of the three heart bid and no questions were asked. After the second double, North asked whether the first double had been for penalties and East replied that she didnt know.
Playing in 4H doubled, South made 5 tricks. The (playing) director was called at the end of the hand, west confirmed that the double was intended as penalties. East / West did not have convention cards and it was not possible to ascertain their actual agreement (if any?). The ruling was deferred as play was already late.
How would you rule? Please also consider:
Does easts failure to alert constitute a mis-explanation?
Should south have protected himself by asking about the first double before he raised hearts? If so, what is the effect on the ruling?
Do you consider the four heart bid to be speculative? Does this affect the ruling?
If you consider an assigned score appropriate, what results would you consider? (4D-4, 4Dx-4, 3Hx-4, 4D-3, 4Dx-3?).
TramTicket: * How would you rule?
Adjust to 5♣=.
TramTicket:• Does east's failure to alert constitute a mis-explanation?
IMO Yes. The defenders had no agreement or played penalty doubles. In either case, the double should be alerted. (But regulations on alerting doubles make no sense, anywhere. Simpler and better would be: All doubles, except penalty doubles, should be alerted or announced).
TramTicket:• Should south have protected himself by asking about the first double before he raised hearts? If so, what is the effect on the ruling?
Negative is the common meaning, so, IMO, No. (In any case the "Protect yourself" rule is ridiculous -- it penalises non-offenders, whether or not they ask).
TramTicket: * Do you consider the four heart bid to be speculative? Does this affect the ruling?
IMO, No, (But the SEWOG rule is also silly and unnecessary).
TramTicket: • If you consider an assigned score appropriate, what results would you consider? (4D-4, 4Dx-4, 3Hx-4, 4D-3, 4Dx-3?)
IMO 5♣=. East claimed not to know what the double meant. So might well take 3♥X out.
