This auction took place at an ACBL Unit Championship Swiss Teams. Both pairs had considerable experience locally.
South's 1♣ opener was announced as possibly a 2 or 3 card suit.
West's 2♦ call was a pre-empt, according to the answer to North's question before his first pass.
West's first double elicited another question from North, who was told that this double was "penalty, I think."
North chose to escape, assuming South had short clubs and therefore length in the majors. 3♦ asked South to pick a major.
South chose spades and went for 1400, losing 15 IMPs (2♦ made ten tricks at the other table).
The N-S side won the 7-board match by 13 even with the 15 IMP loss, but wanted an adjustment based on East's answer to the question about the double of 3♣.
One N-S argument was that East should have been able to tell from her cards that West's double could not be for penalties.
E-W objected that answers to questions are based on agreements, not on what your cards tell you.
I was the TD and could see some merit in both sides. But when I gave several good players only the North hand and the auction up to West's first double and the explanation that it was penalties, the response was universal: "there is no chance that this double is for penalties."
Your ruling?
