Table result: 3NT+2(W), N/S -460
E/W play 5-card majors. 1♣ is either (i) natural or (ii) 15-19 balanced with 2+ clubs.
East intended 2♣ to be forcing; West interpreted it as a non-forcing limit raise.
North claims that, had he known that 2♣ was intended to be forcing, he would have passed out 2♣.
The E/W convention card confirms that E/W play 1♣-Pass-2♣ as an inverted raise but does not mention the auction 1♣-overcall-2♣.
TD's Ruling
The Director awarded a score of 80% of minus 150 to the North-South pair, 20% of minus 460.
Basis of TD's Ruling
Having spoken to East and West, he was "convinced" that they did not have an agreement about the meaning of 2♣. This, in addition to the fact that East-West did play 2♣ as forcing if North had passed, was all the information to which North was entitled. In those circumstances North might bid again but would probably pass – the weighting assigned to the respective probabilities was that North would pass four times out of five.
Basis of Appeal
East/West appeal, saying that (i) they are not sure what they have done wrong ; (ii) N/S misdefended 3NT to allow it to make 11 tricks and (iii) the TD's adjustment has turned a very good score into a very bad score for them.
