~Minorwood (Keycard Gerber)

Minorwood (Keycard Gerber)

This convention is used when a known minor suit will be trumps. If the opponents have not bid (no competition), 4C is Minorwood for clubs and 4D is Minorwood for diamonds. After 4C or 4D, use the 1430 format; the cheapest response shows 1 or 4 keycards, the second cheapest bid shows 3 or 0 keycards, the third cheapest bid shows two keycards without the trump Q, and the fourth cheapest bid shows two keycards with the trump Q.

 

Remember that there are five keycards–the four aces and the trump K.

 

So, over 4C (Minorwood), the following responses apply:

~4D: 1 or 4 keycards

~4H: 3 or 0 keycards

~4S: 2 keycards without the trump (club) Q

~4NT: 2 keycards plus the trump Q.

 

Note that the requestor can stop at 5C if the response does not indicate that a slam should be bid.

 

If the Minorwood inquiry is for diamonds (4D), the responses are

~4H: 1 or 4 keycards

~4S: 3 or 0 keycards

~4NT: 2 keycards without the trump Q

~5C: 2 keycards plus the trump Q.

 

Requestor can still stop at 5D if the response so indicates.

 

How does requestor now ask for kings? By bidding the cheapest suit that is NOT 4NT (to play) or 5 of the trump suit (to play).

 

So, if the bidding goes

1C-4C (Minorwood)

4S (2 keycards w/o the trump Q)

Requestor bids 5D to ask for kings, and 4NT or 5C to play there.

 

But if the bidding goes

1C-4C (Minorwood)

4H (3 or 0 keycards)

Requestor bids 4S to ask for kings.

    It would seem to me you would use the next bid not 5m or 4NT to ask for the queen. Without the Queen respond 5m, with the queen bid cheapest King if you have one , else bid 6m.

    5 of the suit above the minor would show all key cards and ask for kings looking for 7. If only playing matchpoint you may want to ask for kings without all the KCs looking for NT.
