6 ♥ by South

Lead: ♦ 9

Made 7 — NS +1010

While south has only 12 hcp the fifth heart and singleton spade make slam more likely. Here for example we have slam opposite ♠ xxx ♥ Kxxx ♦ AKxx ♣ Ax, which is only 14 hcp. Having said that these hands with a shortage are a problem for the system after the three of a major raise as there is no unambiguous way to show the shortage.

Here though opener shows extra values with 4 ♣ and more importantly denies a spade control. That lack of wastage in spades really encourages south.

North can hardly have something like ♠ Qx ♥ Kxxx ♦ Axxxx ♣ AQ as that would be a strong candidate for a 1 NT opening. Therefore we should takeaway one of those queens and replace it with the ♦ K. It is pretty much impossible to imagine a hand here where slam is not a big favourite.

Just for safety we bid 4 NT and then stop in six when one key-card is missing.
