Roman Keycard Blackwood

[nielsfoged]

This weekend during the Danish Bridge Festival, I faced the following bidding by my opponents (no interference from us):

 

1♠-2NT, 3♣-4♣, 4♥-4NT, 5♥-6NT, all pass.

 

Before my lead, our opponents explained their partner's respective biddings:

Declarer: "1♠ shows an opening hand with 5+ spades"

Opener: "2NT is GF with spade support"

Declarer: "3♣ minimum opening without singletons"

Opener: "4♣ cuebid"

Declarer: "4♥ cuebid, and no ♦ cuebid"

Opener: "4NT is Roman Keycard"

Declarer: "5♥ shows 2 aces of 5 and trump Q.....!!!

 

After complete silence for 10 seconds, my partner and I bursted out in laughs together with Opener, whereas it took a little longer for Declarer to realize that he had just invented a new and smooth alternative to the Alcatraz Coup* (even in a NT-contract).

:)
