RKC Minorwood is a bridge convention which looks for all the keycards in a minor suit at a lower level that the normal 4NT RKCB
If you play inverted minors for example then the sequences will fit into this system:
1♣-2♣-4♣
So here 4♣ is RKC minorwood and the responses are:-
- 4♦ – 1/4 Keycards
- 4♥ – 0/3 Keycards
- 4♠ – 2 Keycards
- 4NT – 2Keycards + Queen of clubs
A Next suit bid up would ask for the Queen of clubs.
A 4NT bid would be a sign off and a 5♦ would be the specific king ask…where the response are to cue bid your kings or bid the king you haven’t got if you have 2 kings. Here you can use hearts as diamonds, spades as hearts and NT’s as spades.
So a 5NT bid would show the king of spades or the King of diamonds and hearts.
1♦-2♦-4♦
So here 4♦ is RKC minorwood
- 4♥ – 1/4 Keycards
- 4♠ – 0/3 Keycards
- 4NT – 2 Keycards
- 5♣ – 2Keycards + Queen of diamonds
A Next suit bid up would ask for the Queen of trumps
A 4NT bid would be a sign off and a 5♣/♥ would be the specific king ask…where the response are to cue bid your kings or bid the king you haven’t got if you have 2 kings.
