[mycroft]

I did this once, playing with a very pleasant Life Novice against a pair of boorish drunks (who, to their credit, admitted to both). My partner kept ending up on lead with cards she never thought would take tricks, exited passively, and declarer kept finessing against what had to be in my hand. I'm sure it would have been -1; it was -4. She sure wouldn't have doubled.

It's not a psychic - you expect to set this contract; it's not insane - you expect to set this contract. It is deceptive, as several above have said, and you do hope to set it more because of that. But why would you pass out this hand when you're reasonably certain it's going down from the auction and your hand?
