A deal from the current challenge event:

 

Declarer concedes a trick In a 4-card-ending,

where all his cards are winners.

Legally, should Gib be credited with a trick that it can't win

unless declarer leads a loser from dummy and discards his ♠ winner [/hv]

The lead is in dummy and declarer pitches the spade winner on the losing diamond or club winner. (AKA - Winner on Loser play). I don't see anything wrong with GIB accepting this claim.

 

A different situation would be if South was leading at trick 10. Now there is no possibility of EW legally winning a trick, so I would expect that GIB would reject that claim.

If a declarer claim is wrong and so can lose a trick in this ending I would not argue with the claim as a defender. GIB agrees. It is human. lol
