6 ♣ by North

Lead: ♣ 9

Made 6 — NS +920

Again 3 ♠ shows slam interest if opener is 15-16. Opener does have extra values so bids 3 NT to show a spade cue. Note this also confirms precisely a 2=4=2=5 distribution. After the 4 ♣ cue, opener bypasses 4 ♦ which is great news for responder. When one key-card is missing another problem arises.

Is 6 ♣ to play? If we are missing the ♥ A or even the ♥ K and it is losing then there will be a possible club ruff in 6 ♥. Even without that there is an appreciable chance that the clubs are 3=0.

In other sequences a new suit after Blackwood is not to play but it makes sense here when the club fit can easily be better than the hearts that we can return there to play.

That poses a problem when you are missing the queen in the second suit but there are always 2=2 breaks to help out there.
