RKC0314
Aces plus King of Trumps are key cards
In response to 4N,
5C shows 0 or 3 key cards
5D shows 1 or 4
5H shows 2 without the trump queen
5S shows 2 with the trump queen
The first two responses may be reversed (playing RKC1403).
5 NT does not necessarily ask for kings. The second step asks for kings.
If Partner bids 5C or 5D, responder bids the cheapest bid short of signoff to ask for the queen.
That is:
over 5 C if:
Clubs or Spades are trump:
5 D asks for trump Q
5 H asks for kings
Diamonds are trump:
5 H asks for trump Q
5 S asks for kings
Hearts are trump:
5 D asks for trump Q
5 S asks for kings
over 5 D if:
Clubs or Diamonds are trump:
5 H asks for trump Q
5 S asks for kings
Hearts are trump:
5 S asks for trump Q
5 NT asks for kings
Spades are trump:
5 H asks for trump Q
5 NT asks for kings
over 5 H if:
Clubs, Diamonds, or Hearts are trump:
5 S asks for kings
Spades are trump:
5 NT asks for kings
over 5 S:
5 NT asks for kings
There are two ways to show the trump queen if asked:
a. The first step after the asking bid denies the queen, the second step shows the queen, OR
b. Rebid the trump suit at the cheapest level to deny the queen. Bids the nearest suit in which s/he
has a king to show the queen (as well as the king of the bid suit, obviously). With no side kings s/he bids
5nt or 6 of the agreed suit if 5nt not possible.
You can show kings in at least 3 different ways
a. each step shows 0,1,2,3 kings
b. each step shows 0/3,1,2
c. each person begin bidding up the line, cheapest level king first. O kings are shown by bidding 6 of the agreed suit.
