2 NT = jacoby, inv + 4+spade
4 D = cuebid (for the Norwegians this bid shows at least 2 hearts, because dbl shows shortness)
As you see, the biddings was the same on both table, except that Sweden stopped in 5 spade. If Eide choose to dbl 5 heart, it would have showed a hand with minimum, so now 5 spade from Eide made it easier for Ellingsen, because it looked like partner was short in heart, and he could raise to 6 spade. This kind of boards is decisive in short matches as here in the Nordic Championship.

Kristian Ellingsen raised to 6 spades, but Ida Grønkvist passed.
