Scissors coup

Scissors coup (or, Scissor coup, also at one time called The coup without a name ) is a type of coup in bridge, so named because it cuts communications between defenders. By discarding a card or cards either from declarer's hand or from dummy or both, declarer can stop them from transferring the lead between each other, usually to prevent a defensive ruff.

Consider this hand and auction with an opening lead of the eight of hearts.

The solution is elegant: upon winning the king of hearts declarer must cross to the king of spades and lead the king of clubs, throwing away the jack of hearts! By this Scissors Coup, East can no longer gain the lead.
