2/1 Bidding System

~2/1 Bidding System

2/1 is not a convention but a style of bidding, a starting point from which basic bidding concepts are matched with certain of a myriad of conventions to form a bidding system. Some people consider 2/1 vastly different from Standard American and only play certain portions of 2/1; however, 2/1 should be played as a complete system.
~Played in this manner, 2/1 is a superior method of bidding than is Standard American. Some of the main tenets of 2/1 are
~5-card majors (some third-suit alternatives)
~Forcing 1NT over major-suit openers by an unpassed hand
~A two-level bid in a lower-ranking new suit by an unpassed hand after a major-suit opener is always forcing to game
~Constructive single level major raises show 8-10 points and 3-4 trumps
~Limit major raises show 11-12 points and 4-card support
~Jacoby 2NT with 13+ points, 4+ trumps, and no splinter nor qualifying
5-card side suit
~Splinter bids–(opening count+and no honor points in the splinter)
~Weak jump shifts (some other options)
~System reverts to Standard American in competition
~1D-2C shows 11+ HCP and initiates a structured search for a 3NT contract (other options exist)
~Certain conventions that complete the 2/1 bidding system, such as New Minor Forcing and Fourth Suit Forcing

No bidding system is foolproof; however, if  bid with discipline, the 2/1 system will improve any bridge player’s bidding. Follow the rules, but remember that bridge judgment cannot be legislated; develop a sound system of bidding and develop your judgment through study and experience. Each partnership should add those conventions to their basic 2/1 bidding system that allow either partner to show weak, intermediate, or strong opening or support hands. The purpose is to improve the competitive bids and the game tries. Some of the conventions and techniques shown below are based on this approach.

Once you add those conventions and techniques which you and partner like to the 2/1 bidding system, you have developed your personal bridge system. Your bridge system should include your offensive and defensive bids, your defensive carding, and your leads.
