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.

If you bid 5♥ to ask for kings…then you need to use spades as clubs, NT as diamonds and clubs as hearts.

So a 5♠ bid would show the king of clubs or the King of hearts and king of spades.
