The '''Carrot 4NT''' slam-convention was developed in [[Carrot Club]], but can be used in any bidding system instead of the more common Blackwood or RKC conventions. It is a refinement of an older convention, [[Culbertson 4NT]].

Rather than asking for Aces or keycards, [[4NT (bid)|4NT]] is used to ''show'' number of keycards.

This convention applies when 4NT is preceded by [[cuebid]]s, and generally when 4NT is a non-jumping bid.
The immediate advantage of this approach over [[Blackwood convention|Blackwood/RKC]], is that while still establishing the combined number of keycards, 
the pair will be able to use the 5-level for cuebids, too, to more thoroughly explore and negotiate their slam-potential.

Normally, 4NT shows at least '''3 out of 5 keycards''' (including the King of trumps) '''plus''' first or second round control in any suit(s) not yet cuebid.

Thus, if a player by-passes 4NT or omits bidding 4NT when he logically could,
it means that he ''either'' lacks the required number of keycards ''or''
that he lacks control in a side-suit that has not yet been cuebid.

If a player has already shown a 17+hcp hand (by reverse-bid, big-club opening, takeout-double followed by new suit, etc.), 
his partner's 4NT promises only '''2 out of 5 keycards'''.

If a player has opened with a strong 2C or shown a 20+ balanced hand,
and later bids 4NT, he promises '''4 out of 5 keycards'''.

Under this convention, 4NT is still Blackwood or RKC when it is a ''jumping'' bid and not a natural raise.
Also, if a player opens, raises, or jumps to 4H/4S without any preceding cuebids, 4NT by his partner is Blackwood or RKC.
Likewise, in competitive situations where opponents have bid at the 3- or 4-level, 4NT is Blackwood or RKC.
