[blml] Réf. : Yet another Ghestem misbid

[Alain Gottcheiner]

-------Message original-------
 
2C was offered as the correction and declined by offender's LHO.
Offender then opted to let his original call stand, thereby causing his
partner to pass for 1 round.
 
 
# Strange procedure. Why did the TD compel the defendent to compound the
offense ?
 
 
The complete auction was then
1H 3C X P
3N P P P

Q1 At the stage that N has indicated that he wished to change his bid,
but has not yet done so, could he elect to remain with his original call
and not go through L25B?
 
# Yes, but look at the amount of UI. Nothing short of 4S would be admissible
from South (although I could have bid 4C "cue", absent UI, because I smelled
the rat).
 
Q2 What are the UI implications of electing to change to 2C and then
letting the call of 3C stand? In particular should S still be bidding as if
it showed Spades + Diamonds?
 
# A bit more than absent the intended corection, which is why the TD is
partly guilty and could think about using L82. Absent that, North's remark
could be taken as showing another two-suiter, or whatever. But the remark
above still holds.
 
However, UI aside, I'd apply L23 and L72B1, as North could have known his
revealing the mistake (an infraction to L73B1) and the ensuing penalty
(forced pass) could probably help his side.
 
Q3 What lead penalties should apply?
 
If the attempted correction is allowed, none. If 3C is enforced, as it is an
artificial call in their system, apply L26B *if* South is on lead, which he
isn't. But I'd anyway correct to 4SX minus whatever according to L72B1 AND
tell them a second Ghestem mistake would compel them to ditch that part of
their system. 
 
Best regards
