- These are system questions, and my annotations were intended to indicate that
- in my preferred 2/1 system, 1D-2C really is game forcing, even if responder
- rebids 3C.
-
- In Hardy 2/1, 1D-2C is game forcing regardless of continuation (well, it could
- possibly die in four of a minor if both hands are minimum and there's no fit),
- and 1D-2C-2M does not show extra values. In Lawrence 2/1, 1D-2C is only
- invitational if responder rebids 2N or 3C, and 1D-2C-2M does show extra values.
-
- This hand is an example of why I prefer to treat 1D-2C as strictly game forcing
- -- I don't know how to bid this fine slam if it isn't. (Note that this
- treatment requires that 1D-2N and 1D-3C both show about 9+ - 12-.)

- Opener's hand is worth 16 or 17 points. Isn't that enough for a reverse that
- promises extra values?

- Not forcing, according to Lawrence! (1D-2C,2S-2N is forcing, since opener
- has shown extra values.)

- The basic premise of the 2/1 system is that auctions starting with a truly
- game forcing 2/1 become much simpler because both partners can bid without
- worrying about which continuations are forcing. This hand seems like a fine
- example. If 1D-2C doesn't create a game force, all sorts of problems emerge.
- If 1D-2C does create a game force, then opener can simply bid his
- second suit, responder can simply rebid his stellar five-card suit, opener
- can show three-card support below game, responder can suggest a slam by
- cuebidding below game, and opener, with extra values and control of the
- other two side suits, can accept.
-
- Defining all 2/1 sequences as game forcing requires several special agreements
- to handle hands that would start with 2/1 in Standard American but aren't good
- enough to force game. Lawrence doesn't like some of those special agreements,
- so he avoids them by making some 2/1 sequences not game forcing. He gives up
- easier auctions on some hands that are good enough to force game in exchange
- for easier auctions on some hands that aren't good enough to force game. He
- also gives up the simplicity of the agreement that 2/1 is game forcing. One
- result: he needs fifty-some pages in his book to discuss 1D-2C auctions (it's
- much the longest chapter)!
