Denmark increased the lead in the beginning of the last session. They were ahead by 19 imp when this board appeared.

As you see the auction was quite similar, but it looks like there was a misunderstanding with 3 spade for the danes when Jepsen decided to bid 4 spades rather than 4 hearts. Skjetne led his queen of diamond, small, small small. He switched to a club, and when Grude cashed his Ace of diamond they made the perfect defence for down 2. 13 Imps to Norway when 4 hearts by North is unbeatable.
