(1) A balanced raise to three spades or higher
Another deal from the Swiss Pairs at the Lancashire Congress in Preston in October.
This deal demonstrates that it is not always a good idea to have too much science in the bidding.
When West bid three diamonds to show the spade raise North was able to double for the lead.
South duly led a diamond, there was nothing to the play and declarer quickly made ten tricks.
At other tables South normally led a heart, with declarer now being able to throw his diamond on the hearts making eleven tricks.
