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.
Indiana Jump Bid is a popular bidding convention in the game of Contract Bridge. It is a special bid that carries a specific meaning and is used to convey important information about the bidding hand. The term "Indiana" refers to a state in the United States, where this bidding convention was allegedly first employed. The primary purpose of the Indiana Jump Bid is to show a strong, preemptive hand with a long and solid suit. It is used by the responder to demonstrate their hand strength and suit distribution to their partner, allowing them to make informed decisions during the subsequent bidding process. There are two main types of Indiana Jump Bids: the Simple Indiana Jump Bid and the Reverse Indiana Jump Bid. 1. Simple Indiana Jump Bid: This type of jump bid is made by the responder after the opener's suit bid. It requires a strong, preemptive hand with a long and solid suit, typically six or more cards. The bid implies the intent to compete aggressively and potentially obstruct the bidding opponents. This bid allows partners to find an optimal contract quickly or even to make a sacrifice bid when necessary. 2. Reverse Indiana Jump Bid: Unlike the simple version, the reverse Indiana jump bid occurs after the opener's no trump opening bid followed by a suit response by the responder. This bid also indicates a strong hand with a long and solid suit. It suggests that the responder has no interest in playing in no trump and encourages the opener to continue bidding to explore possible contracts in their suit.
