In bridge, a Cooper echo is a facetious high-low play by declarer to tell partner that the contract will succeed. Once declarer ascertains that the contract makes, he plays high-low in one of dummy's suits.
The purpose of the Cooper echo is merely to provide dummy some relief about the fate of the contract.

West leads the
2 (fourth-best) against 3NT. Declarer can count 9 top tricks, so he plays the 7
from dummy. This immediately assures partner that the contract will make.
Note that the Cooper echo is off if declarer needs to unblock the suit, as with an honor doubleton.
The Cooper echo was invented by Peter Cooper of Vancouver, B.C.
