| (1) 12-14 (2) alerted, explained as natural and forcing (3) penalties (H) undisputed hesitation NS have agreed to play Lebensohl in this situation. Direct 3-level suit bids are forcing, weaker hands go via 2NT. This is on the convention card, South had forgotten. South led 5 to the queen, North switched to the K. East won, drew trumps and discarded a club loser on a heart to make ten tricks. |
South has UI from the explanation but suppose Pass is not a logical alternative to 4 ; and suppose it is established that South has misbid and the explanation is correct, so there is no misinformation. So NS are non-offending.
Suppose further that Pass is a logical alternative to 4 and 4 is suggested over Pass. So 4 is using UI and EW are offending. We adjust to 4 for EW.
But what about NS? Should we deny them redress because they failed to defeat 4 ?
Is playing K a serious error?
No. It is an entirely reasonable given South's bidding.
Is South's bidding (3 = nat, GF) a serious error?
Yes.
Does it matter that 3 was a serious error committed prior to the infraction by the opponents?
Does it matter that 3 was a serious error whose negative consequences ( K switch) did not occur until after the infraction by the opponents?
