In the card game of bridge, a specific bidding sequence is employed to inquire about the availability of major suit holdings by one’s partner, especially after an opening bid of one no-trump. This action aims to uncover potential 4-4 or longer major suit fits, which are often preferable to playing in no-trump contracts.
The primary advantage lies in the ability to locate a major suit game more effectively. Prior to its widespread adoption, partnerships often struggled to identify these favorable suit contracts. This technique streamlined the bidding process, leading to more accurate assessments of hand strength and distribution. Its introduction revolutionized competitive bidding in bridge, leading to more successful contract declarations.
