At Achray House near Loch Earn me and Anna watched some of the North American Bridge Championships. The winning team featured Sabine Auken, from Germany, and Roy Welland. Here's a hand which prompted Anna to say "looks like magic, they must be cheating".
This is a board from the Semi-final. Everyone plays Strong NT and 5 Card Majors, so East opened 1♣. West replied 1♥, and East raised to 2♥.
South now knows that East has a minimum opener, and knows West isn't too strong as he's a passed hand. South can't double though (that would show minors), so comes in with 2♠. North replies 2NT, and South correctly interprets this as minors and bids 3♣, passed out.
One expert commentator said "NS seem to be on the same wavelength here", and the other added "it's like stealing, well done by South".
3♣ made. On the other table EW played 3♥+1, so overall it was a 7 IMP gain for Team Auken, who went on to win the semi-final and the final.
