A "Merrimac Coup" in bridge usually refers to the "suicidal" lead of a king, in order to force out an opposing ace before the opponent is ready to use the ace as an entry. If that hand (usually dummy) is short of entries, this might cause "transportation" problems in establishing and cashing a long suit.
Suppose I can see that dummy has a broken long suit, and a side ace. Would this be a good time to try the Merrimac Coup?
Suppose I am the opening leader, with a king. Are situations based on the bidding and my holding where I should try a Merrimac Coup before seeing dummy?
Are there situations where declarer was originally a responder, and might be short of entries, so that I should try a Merrimac Coup into the "closed" hand?
And can there be a Merrimac Coup with a card other than a king? Suppose I have A-Q of a suit as opening leader, lead the ace, and see a king (plus a long suit) in dummy. Would the lead of the queen to dummy's king constitute a Merrimac Coup?
