Arkansas Jump Bid, also known as the Arkansas Convention or simply the Arkansas, is a popular bidding system used in contract bridge. It is a convention used primarily in the game of duplicate bridge to convey specific information to your partner about your hand. The Arkansas Jump Bid is a forcing bid, meaning it forces partner to respond and prohibits them from passing the bid. In the Arkansas Jump Bid, the responder makes a jump to a higher level in a new suit (no trump rebids excluded) to show a hand that is too strong for a simple response but not strong enough to jump to a game. This bid is traditionally used with hands that contain 10-11 high card points (HCP) and a long suit, although variations exist. There are multiple types of Arkansas Jump Bids, namely: 1. Weak Jump Bid: This is the most common variation of Arkansas Jump Bid. It is used when responder has a weak hand with 10-11 HCP and a long suit. This bid helps the partnership to explore potential major suit fits while keeping the bidding at a lower level. 2. Strong Jump Bid: In this variation, the responder has a stronger hand with 12-15 HCP and a long suit. By making a jump bid, the responder conveys the high-card strength and urges the partnership to investigate the possibility of a game contract. 3. Reverse Arkansas Jump Bid: This bid is made by the responder when they hold a weak hand with a longer and stronger minor suit, usually a 6-card suit. By jumping to a higher level in a minor suit, they show their intention to explore the possibility of playing in a minor suit game. 4. Fit-Jump Arkansas: This is a special variation used when responder holds a weak hand with 10-11 HCP and exactly three-card support for partner's major suit. The responder jumps to a higher level in the major suit, indicating a fit and encouraging partner to continue bidding. The Arkansas Jump Bid system provides an effective and efficient way for partners to exchange crucial information about their hands, allowing for better decision-making during the bidding process. These bids can help partners find the best contract and increase the chances of success in the game.
