In Bridge, you bid a negative double when you want to tell the opener, your partner, about four- or five-card length in the unbid major(s). You use this bid when, for one reason or another, you can’t just bid the major. Only the responder can make a negative double (but he just says the one word, “Double”) after partner opens the bidding and an intervening overcall takes place.
