In auction theory, jump bidding is the practice of increasing the current price in an English auction, substantially more than the minimal allowed amount. It is a bid higher than necessary to reach the next bidding level, usually to indicate exceptional strength.
Texas Jump Bid is a popular bidding convention in the game of bridge, which is a trick-taking card game. It is primarily employed in duplicate bridge, where players compete against others playing the same deals. In Texas Jump Bid, the responder's jump bid indicates a long, powerful, and preemptive suit, while the opener of the bid shows a strong opening hand. It is a slam-seeking convention that aims to convey critical information about both hands to the partners more efficiently. The Texas Jump Bid can be categorized into two types: the Texas Transfers and the Texas Key Card Blackwood. 1. Texas Transfers: — Standard Texas Transfers: When the responder jumps to a higher level in a new suit, excluding no trump, it is a transfer bid. For example, after the opener bids 1♦, the responder can jump to 3♠, which indicates a strong preference for hearts. — Limit Texas Transfers: Here, the responder's jump bid has a specific maximum point range. It emphasizes the bid suit and is often accompanied by slam interest. For instance, after an opening bid of 1♣, the responder's jump to 3♦ indicates a limit transfer of diamonds. 2. Texas Key Card Blackwood: — Texas Blackwood: This variant modifies the commonly used Key Card Blackwood convention. After agreeing on a trump suit, the responder uses a jump to ask for specific key cards (the four aces and the trump king). For example, after the opener bids 1♠and the responder jumps to 4♦, it asks the opener to respond with the number of key cards they hold. — Control Showing Texas Blackwood: This variation focuses on showing controls in trump suits instead of key cards. The responder's jump bid indicates possession of the ace, king, or void in a trump suit, which helps assess slam possibilities more accurately. In conclusion, Texas Jump Bid is a bidding convention in bridge that efficiently conveys the strength and distribution of both the opener and responder's hands. It offers two main types — Texas Transfers and Texas Key Card Blackwood — each serving a specific purpose within the partnership's bidding system. Partnering players should have a clear understanding and agreement on these conventions to communicate effectively during the auction phase of the game.
