Bridge players keep finding more and more ways to use doubles, especially in low-level competitive auctions. The traditional double by the Advancer is the responsive double. This double applies when the opponents have bid and raised a suit and partner has taken some action in the middle (either a takeout double or a suit overcall). But when Left Hand Opponent (LHO) opens the bidding with a suit, partner overcalls a second suit, and Responder bids a third suit, then a double by Advancer is not a responsive double. It is a different kind of competitive double called a Snapdragon Double – a fancy name for another double that wants to compete in the bidding.
