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.

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

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