The Arizona Jump Bid is a term used in contract bridge, a popular card game played around the world. It is a bidding technique specifically used in the Standard American bidding system. The bid is aimed at gaining additional information about the partnership's combined holdings and capabilities, particularly in terms of distributional strength and the presence of major suit fits. The Arizona Jump Bid is made by a player to reveal a two-suit holding and to invite partner to explore further. It typically involves skipping past one or more bidding levels to indicate the strength and distribution of the hand. The bid can be most effective when the skipped level is a natural suit bid that the partnership has not yet been able to establish. There are different types of Arizona Jump Bids, including the 1NT jump bid, 2NT jump bid, and 3NT jump bid. Each of these bids signifies different strengths and distributional patterns, which allows the partnership to better evaluate their combined assets and make more informed bidding decisions. The 1NT jump bid is made by the opener after an opponent's overall of a natural suit at the one-level. It typically shows a hand with a long, solid minor suit and a stopper in the opponent's suit. The bidder usually skips the typical one-level bid of the minor suit and directly jumps to the 1NT level. The 2NT jump bid is made after an opponent's preemptive bid at the two-level. It indicates a hand with a long, solid major suit and various stoppers in the other suits. This bid is also intended to invite partner to explore further, helping to determine if there is a potential game or slam contract. Lastly, the 3NT jump bid is made after an opponent's preemptive bid at the three-level. It shows a powerful hand with a long, solid suit (usually a minor suit) and stoppers in the other suits. Similar to the previous bids, this jump bid aims to allow the partnership to discover their optimal contract and make strategic decisions accordingly. In summary, the Arizona Jump Bid is a bidding technique used in the game of contract bridge to share specific information about a hand's distributional strength and suit holding. The 1NT, 2NT, and 3NT jump bids are key examples of this technique, each having distinct implications and invites for partner.
