Insufficient Bid - Law 27
Accepting an insufficient bid -
An insufficient bid may be accepted by offender's Left Hand Opponent. If the LHO makes any call, they are deemed to have accepted the insuffient bid. The bid stands if it is accepted.
Replacing an insufficient bid -
If it is not accepted, then it must be replaced by a sufficient bid.
1. If it is replaced by the lowest sufficient bid in the same denomination, and the TD is of the opinion that neither bid is artificial, the auction proceeds with no further rectification.
2. It may also be replaced by another call without penalty, if the TD is of the opinion that the new call has the same meaning in their bidding system, or that it has a more precise meaning which was contained in the possible meanings of the original bid. In that situation, the auction proceeds with no further rectification.
NOTE:- although the bidding continues in situations 1 and 2, the TD may still adjust the score if he judges that the non-offending side has been damaged.
3. If the insufficient bid is replaced by any other sufficient bid or pass, the offender's partner must pass whenever it is their turn to call. If the offender becomes a defender, declarer may forbid or require the offender's partner to lead the suit of the insufficient bid.
4. if the offender attempts to replace the insufficient bid by double or redouble, and that is not a conventional call which complies with 2 above, then they must replace it with a sufficient bid or pass.The offender's partner must pass whenever it is their turn to call. If the offender becomes a defender, declarer may forbid or require the offender's partner to lead the suit of the insufficient bid.
NOTE:- The TD may adjust the score if they judge that the non-offending side has been damaged - for example if the offending side gains because the partner has been forced to pass.
