4 ♠ by South

Lead: ♦ 9

Made 5 — NS +450

I have shown south signing off in 4 ♠. However that is possibly too pessimistic with top cards - ♦ AK and ♣ A. From south's perspective a hand like ♠ AKQx ♥ Ax ♦ Qxxxx ♣ xx would have play for slam.

It is all moot here as with king-small in both short suits north would probably open 1 NT in the real world.
