______ The central theme of the 2/1-GF system is that Responder often must define the auction as game-forcing before the pair has established a fit. The auction 1:2D:2:3D can be dropped in SAYC, but not in true 2/1-GF, when Responder might have 20+ points! The only way to deal with this problem is to devalue any marginal 13-point hand that that lacks support for Opener's suit.

Opposite 1, one might prefer 1NT to 2.

______ A second challenge for 2/1-GF pairs is to limit one of the hands so as to stop short of unmakeable slams. New 2/1-GF pairs have to concentrate their efforts on finding ways to limit their hands as early as possible in game-forcing auctions. One of the best tools for accomplishing this is stringent use of the Principles of Fast and Slow Arrival. After 1:2:2 a rebid of 2 will show 16+ points, while 3 will limit Responder to 13-15 points. Similarly, 1:2:2:3 shows 16+ points, while 1:2:2:4 is a signoff with 13-15. This jump in Partner's suit is called a "necessary" jump since we need it to distinguish the weak from the strong raise of Opener's suit.

______ Jump rebids in Responder's own minor suit (e.g. 1:2:2:4) show a solid suit, 19-21 points and command Partner to begin cuebidding en route to a slam. The opposite is true if Responder jumps in Hearts. 1:2:2:4 is a sign-off with 13-15 points, while rebidding the Hearts up to 4 (e.g. 1:2:2:3:any:4) shows 16-18 points, suggesting a slam.

______ Jumps in new suits are cuebids, showing 19-21 points, confirming Partner's last bid suit as trumps, and commanding Partner to cuebid. This may be Opener (1:2:4) or Responder (1:2:2:4). With 13-15, we will often raise directly to game (e.g. 1:2:4 or 1:2:2:4). Holding 16-18 points, we will raise simply (1:2:3 or 1:2:2:3) so as to leave room for partner to cuebid if interested in slam. It follows that Partner can sign of in game (1:2:3:3NT or 1:2:2:3:4) if disinterested.
