UI + Serious error
A pair after an illegal bid lands to 6nt in which AK are missing in a color. Although the non-offenders revoke, so table result is 6NT=!
I think that there is no doubt that non offenders had their chance, so they get table score, -990.
What about offenders? Do they keep table result after their opponents serious error, or their score is adjusted to 3NT+3 490?
