agreed BIT before second double by North
North hand contains 17PC in 4441 distribution, South hand has 2PC in 3433 distribution, 3 hearts plays for 7 tricks for NS, clubs would have played for 9 tricks for EW.
W summons TD after the end of the deal and states that BIT before the second double suggested that it is for take out rather than for penalties. NS insists that they definitely play doubles in this position for take out.
There is no CC (and conditions of contest does not require CC if that matters). Doubles are not alertable in this jurisdiction.
All players are good and experienced. No questions was asked during the bidding but up to the second double the bidding is very standard and nobody has any doubts about its meaning. As for the second double, field would divide about 50/50 between takeout and penalties.
What would you do? Do you think the task would be any easier if TD were summoned before the end of the bidding?
