When partner opens any Preempt from 2 thru 3
(except 3
) we play that 4
is Special Keycard
When Partner preempts 3 we play 4
as extending the Preempt and 4
as Special Keycard
Responses to Special Keycard are:
Special Keycard is on over Interference so long as it is a jump. If we cannot jump then 4NT becomes Special Keycard.
