INSUFFICIENT BID

These are brief details, the Director must be called as in all cases of irregularity.

The first option is that the next player in rotation may accept the bid. Bidding continues as normal, there is no lead penalty.

1. A natural bid

If the bid was not conventional, it may be corrected by raising to a sufficient level and there is no penalty. If, however, the raising of the bid makes it a conventional bid, the offender's partner must pass for the whole auction and the offender will therefore change his bid.

2. A conventional bid OR

3. Corrected by another bid or pass

The offender's partner must pass for the rest of the auction.

Possible lead penalty

If the insufficient bid specified any particular suit, and it was not repeated later in the auction, offender's partner has unauthorised information. Declarer may require the offender's partner to lead, or prohibit from leading, one of the offender's suits at his/her first turn to lead.

If no suit was specified e.g. 1 no-trump, declarer may prohibit offender's partner from leading any one suit at his/her's first turn to lead.

4. Corrected by a double or redouble

This is not allowed. The call is cancelled and the rules under 2. and 3. above apply concerning penalties.
