NS play a variable NT. In third seat, South claims their agreement is that in 3rd seat they play 9-13 at all vulnerabilities (any hand that cannot have enough for game). North claims that would be suicide to do it when vulnerable. NS can document that their escape methods from 1NT are as follows. If 1NT is mini (10-13 usually for 1st/2nd NV) then XX is a rescue, and all other bids are to play. If 1NT is strongish (13-16) then all bids are transfers. Unfortunately the convention card and system file does not document what range 1NT is in 3rd seat when vulnerable. EW claimed damage, saying that had they known 2D was a transfer to hearts, 2D would've been passed out. How do you rule?
