Conv 1.1 - The Kabel 3NT Convention

Not often do you get a hand like this, but when you do : How are you going to bid this ?

♠ A K     ♥ A K Q 10 9 7 6 4 2     ♦ 7 4     ♣ -

Are you going to open 2♣ ? Or will you bid 4NT directly ? Neither may give you the answer to the only question you want to ask : has Partner got the A♦ ??   And if so, does he also has the K♦ ?

This is where the Kabel 3NT Ace asking opening bid comes in. It is specifically designed for freak hands containing 10 or more tricks or 2-4 losers. (The Responder can also use it as his first response to Partner's Opening bid.)
Replies to Kabel 3NT are as follows :

  • 3NT - 4♣ = No Ace

  • 3NT - 4♦/4♥/4♠/5♣ = Ace in the suit bid

  • 3NT - 5♦/5♥/5♠/6♣ = Ace in the suit bid + Ace in the next suit

  • 3NT - 4NT = Two non-touching Aces

  • 3NT - 5NT = Three Aces

When Opener rebids a suit it is a sign off, if he rebids 4NT it is a King asking bid.
Responder's replies are :

  • 3NT - 4♦ - 4NT - 5♣ = No King (but has A♦)

  • 3NT - 4♦ - 4NT - 5♦/5♥/5♠/6♣ = King in the suit bid

  • 3NT - 4♦ - 4NT - 6♦/6♥/6♠ = King in the suit bid + King in the next suit

  • 3NT - 4♦ - 4NT - 5NT = Two non-touching Kings

  • 3NT - 4♦ - 4NT - 6NT = Kings in both minor suits

  • 3NT - 4♦ - 4NT - 7♣ = Three Kings

If the 4NT bid is not available for a King ask, 5NT is the King asking bid.
Replies are :

  • - 5NT - 6♣ = No King

  • - 5NT - 6♦/6♥/6♠= King in the suit bid

  • - 5NT - 6NT = King of Clubs

  • - 5NT - 7♣ = Two Kings

Here follow three examples.

Ex. 3     Opener (W)
♠ - A K
♥ - A K Q J 9 8 5 4 2
♦ - 8 2
♣ -
  Responder (E)
♠ - 9 7 4
♥ - 7 3
♦ - A J 10 7
♣ - Q J 9 8 6
 

Comment
East shows the A♦ but no King.
West signs therefore off in 6♥


Bidding : (W) 3NT - 4♦ - 4NT - 5♣ - 6♥ - Pass


Ex. 4     Opener (W)
♠ - A K Q J 10 8 2
♥ - 7
♦ - K Q J 10
♣ - 3
  Responder (E)
♠ - 3
♥ - A 9 8 7 4
♦ - 9 5
♣ - A Q J 8 6
 

Comment
East shows two non-touching Aces, which West recognises must be the A♣ and A♥. Small Slam in Spades is therefore certain.


Bidding : (W) 3NT - 4NT - 6♥ - Pass


Ex. 5     Opener (W)
♠ - A K Q J 10 8 2
♥ - 7
♦ - K Q J 10
♣ - 3
  Responder (E)
♠ - 3
♥ - K 9 8 7 4
♦ - 9 5
♣ - Q J 9 8 6
 

Comment
East shows to have no Ace at all and West signs off in Game.


Bidding : (W) 3NT - 4♣ - 4♠ - Pass
