Useful Gadgets (2) Roman Key Card Blackwood |
Show Detail |
Using 5-card Puppet Stayman (see above) North discovers a 5-3 Spade fit
Playing ordinary Blackwood North can only discover four Aces
Roman Keycard Blackwood asks how many of five Key Cards do you have?
(the five Key Cards are the four Aces and the King of Trumps)
When North bids 4NT (RKCB) South will reply as follows:
- 5♣ = I have none or three
- 5♦ = I have one or four
- 5♥ = I have two or five but do not have the Trump Queen
- 5♠ = I have two or five and I also have the Trump Queen
When South bids 5♠ North can work out South must have 5 Key Cards (all four Aces and the ♠ K) and the ♠ Q
That is enough to bid 6♠ but stop short of 7♠ since South cannot have the ♣ K as well or they would have exceed the 22 points max for their 2NT opening

Show Answer |
You'd like to say "have you got a 5 card Major suit partner?".
Well the good news is you can if you play 5-card Major Puppet Stayman over 2NT
3♣ asks "have you got a 5 card Major suit partner?".
Partner then responds:
- 3♦ = I don't have a 5CM but I do have a 4CM
- 3♥ = I have 5 Hearts
- 3♠ = I have 5 Spades
- 3NT = I have neither a 5-card, nor a 4-card, Major
After the sequence 2NT - 3♣ - 3♦
- 3♥ says I have Four Spades
- 3♠ says I have Four Hearts
- 3NT says I have neither Four Hearts nor Four Spades
- 4♦ says I have Four Hearts and Four Spades
