New York Jump Bid is a bidding scheme used in contract bridge, particularly in the Standard American system. It is a conventional bid that carries a specific meaning and is used to convey certain information to the partner. This strategy is often employed in competitive auctions when an opponent has opened the bidding with a suit bid. The New York Jump Bid indicates a strong hand with a long suit, at least 9 cards in length. It is made by responder (partner of the opener) after an opponent's suit bid and involves jumping to a higher level in a new suit. The bid shows that the responder has a good hand and wishes to compete further in the bidding. The specific level and suit chosen in the jump bid convey further information to the partner. There are different types of New York Jump Bids, based on responder's available high-card points (HCP) and the specific suits involved. Some common variations include: 1. Weak Jump Shift: This type of New York Jump Bid is made with a weaker hand, typically 5-9 HCP, but with a long, strong suit that the responder wishes to emphasize. For example, if the opponent opens with 1 spade, the responder may bid 3 hearts (jumping to the 3-level) to show a long, weakish heart suit. 2. Strong Jump Shift: This variation of New York Jump Bid is made with a strong hand of around 16+ HCP and a long suit. It signals a powerful hand and the desire to compete aggressively in the bidding. For instance, if the opponent opens with 1 diamond, the responder may bid 3 hearts (jumping to the 3-level) to indicate a strong, long heart suit. 3. Intermediate Jump Shift: This type of New York Jump Bid falls between the weak and strong versions, typically with 10-15 HCP. The responder's aim is to convey a good hand but without enough strength for a game-forcing bid. It helps partner judge the overall hand strength more accurately. New York Jump Bids are a useful tool in bridge auctions as they enable partners to quickly convey the strength and distribution of their hands. By using these bid types appropriately, players can better understand each other's holdings and make informed bidding decisions.
