Kabel Three No Trump Opening
Kabel 3 NT Opening
The origin of this conventional method is unknown. The concept is to determine the location of specific Aces and Kings with an opening of 3 No Trump. The opening bid is forcing and implies a very strong holding with three or fewer Losing Tricks. After determing whether partner holds any specific values and the location thereof, the opener is then able to set the correct contract at the correct level.
The responses to a forcing 3 No Trump opening are as follows:

Once North discovers that partner holds both the Ace and King, then North bids the grand slam, knowing that there are no losing tricks in Diamonds. The only danger to the fulfillment of the contract would be a 5-0 split in trump topped by the Ten.
