free bid by opponents 1NT(15-17)-2♣-2♥-3NT-4♠-5♦ ALL PASS there was screen at the table. my partner called the director after we finished the board and his decision was that there wasn't anything blameworthy at the bidding.we said that it was a psychic bidding in order to avoid a possible major leading when the dummy had a singleton and a doubleton. so 5 ♦ should be cue bid with ♠ fit and if the opener had a maximum 1nt should have accepted and continue the bidding the final contract should be 6♠ or in case of a minimum 1nt the final contract should be 5♠ any opinion about it? thank you and sorry for my english
