Alerting Rule Changes - 1 August 2013

When you open 1C or a natural 1NT there will be no need to alert the bid. Instead, the responder must announce the meaning of the bid.

1NT Give the strength range, 12-14, 15-17 or whatever applies

1C The announcement depends on the system:

For a natural system, the responder announces the minimum length guaranteed.
For a strong club system, the point range is announced.
For a club opening with multiple meanings, it is announced ‘unusual’.
