- In its simplest terms, the "system" described as 2-over-1 game-forcing refers to the following 6 bids : 1 - 2 1 - 2 1 - 2 1 - 2 1 - 2 1 - 2 These are the only 6 possible "2/1" auctions. Anything else would be either a raise, or a jump-shift (such as 1 -2 is a raise and 1 -2 is a jump-shift).

2/1 GF is by far the superior (and easier system). If teaching beginners, I would start out with 2/1 GF . Most bridge teachers agree with me. In "Standard," if your partner opens 1 and you respond, say, 2, it is natural and 10+.
2-over-1 is game-forcing as long as responder is not a passed hand and there is no interference bidding (so, in competition, 2/1 is NOT game forcing). The 2/1 Game Forcing system is really an outgrowth of Standard American and 5-card Majors and many of the methods and conventions employed are alike.

One of the most popular biddingsystems in the U.S. is the 2-over-1 Forcing-to-Game system. It's based onStandard American with 5-card majors. The main difference is in the meanings of2-level responses to an opening bid. The general approach is just as thename suggests: If responder's first bid is 2 of a new suit (1S by opener - 2C,2D or 2H by respo...
2-over-1 forcing-to-game is"on" only when your side opens 1D, 1H or 1S in 1st or 2ndseat and the next player passes and responder makesa non-jump bid of 2 of a new suit. The only relevant auctions are: 1♥-2♣1-2♦1♠-2♣1♠-2♦1♠-2♥ 1♦-2♣ Note that the auction 1D-2C is a bit different than the others because the Forcing Notrump -- the response you use wi...
There are several ways to structureyour 2-over-1 system. The most widely used approaches are the systems proposedby bridge writers Mike Lawrence and Max Hardy. The two systems are similar, butthey differ in the meanings of some of opener's rebids. Questions to ask your 2-over-1partner: 1. Do you play "Hardystyle" or "Lawrence style"? Most of the re...
Your priorities for your firstresponse: 1. First: Make the appropriate raise of partner's major if you have 4-card support(single, limit or forcing raise) OR 3-card support with5-10 points (single raise). The only supporting hand that will notmake an immediate raise is one with 3-card support and a good 10+ points. See Raisingpartner's majorbelow f...
Opener’s secondbid: One of the common misconceptionsabout 2-over-1 auctions is that after the forcing-to-game response, neitherpartner has to jump to show extra values. This is only half right. The generalguideline is that responder does not jump with strong hands, but opener does. In most 2-over-1 auctions, responderis the "captain" because he has...
Responder’s “low raise” (1H-2C-2NT-3H)shows at least moderate extra values, but it does not demand a cuebid.Opener should make a cuebid only if he has more than a dead minimum.If opener makes an early cuebid in responder’s2-over-1 suit (1H-2C-2NT-3H-4C), it should show a fitting card (ace,king or queen), usually with moderate support (doubleton or better). It doesnot nec...Other cuebids show a first-round control (ace orvoid). Bid your cheapest control. If your cuebid"skips" an unbid suit, it denies a control in that suit. In theauction 1H-2C-2NT-3H-4D, your 4D cuebi...After you've found a major-suit fit (1S-2H-3C-3S),a bid of 3NT demands a cuebid. It is not a suggestion of a final contract.In a nutshell, here is what/why this 1NT forcing animal exists: In Standard, a 1NT response is 6-10 (because you can go to the 2-level with 11 or 12 or 13 or more). In 2/1 GF, a 1NT response is 6-12 (because you need 13 to go to the 2-level). Do you see the difference?
Two Over One (2/1) Game Forcing is a natural, 5-card major bidding system. When the auction begins 1 / / , a simple 2-level response in a new suit is forcing to game. This page provides articles, convention writeups, and resources to help learn the system.
