4NT for Kings
Kings are shown in the following 4 steps if responder's initial response was a positive:
- No Kings
- 1 King
- 2 Kings
- 3¦4 Kings
This response
taken with the initial response to 2C allows the 2C opener to decode
BOTH the number of Aces & the number of Kings held by the responder.
This 4NT request for kings is not available with any other opening bid.
If the initial response to 2C was a negative or a break-out then the 4 step responses are very different as follows:
- No Queen
- Q of trumps
- Q & J or T of trumps
- Q of trumps & a further useful Queen
After obtaining the number of Kings, 5NT can be used to ask about Q's as in the 4 steps above.
