It is contract that given declarer holding certain cards and dummy holding certain cards requires the leading defender and other defender to hold specific cards. Basically this contract has most remote chance of making and how low a percentage is that? I would think the contract would be 1NT. What is the situation where the lowest chance of making contract has so specific card holdings to make? Bridge is not symmetrical since there is the lead asymmetry.

The optimal 1 in 10400600 seems trivially achievable:


7NT requires East to hold all 13 clubs, so only one of the 26C13 possible layouts works.

That is correct for defenders but what about declarar and dummy? In that example dummy and declarer could hold any of those 26 cards.
