rbforster Posted February 16, 2010 Report Share Posted February 16, 2010 Some people play a strong club with a GF 1♦ response, although the rest of the structure seems less familiar. I suppose the very weak 1M openings aren't legal many places (although you could swap the 1M and 2M openings). I don't see a bid for 5+M with 13-15.

dcohio Posted February 16, 2010 Author Report Share Posted February 16, 2010 I think I have the 1M bids wrong... they must be the 13-15 bids. I left my page of notes at home and am trying to remember what we talked about. =) I do know the system was designed for GCC legal...

A 0+ diamond and EHAA-style weak twos seem like a nice combination of sound-but-ambiguous 1m openers and preemptive 1N/2X openers. I expect if you want a more comprehensive and thought-out scheme for 1♣-1♦ GF, you might check awm's system or the later versions of Moscito's strong club. I think most of those use a double negative response (typically 1♠), and use the other responses (up through 2M) as various semipositives.

spotlight7 Posted February 16, 2010 Report Share Posted February 16, 2010 Hi: There is no bid for 0-5 without a 5+ suit. Regards, Robert Quote Link to comment Share on other sites More sharing options...
straube Posted February 16, 2010 Report Share Posted February 16, 2010 I don't like it. This structure is way too preemptive. Weak responders give too much direction to the auction. Quote Link to comment Share on other sites More sharing options...
SteelWheel Posted February 17, 2010 Report Share Posted February 17, 2010 Dan O'Neill hosts a writeup on his website of something similar to this, called "Revision Club". In briefest summary, a 1♦ response is a waiting bid, similar to the 2♦ waiting response to 2♣ in standard systems, and can be any game force hand, balanced or otherwise, or a balanced 0-7. All immediate suit responses are natural and deny a game force opposite a 16 count. Sort of a "Reverse Precision" concept. Interesting idea...

akhare Posted February 17, 2010 Report Share Posted February 17, 2010 Actually, I came up with something very similar a while back :P. You may want to consider playing 12+ - 15 for the 1 level openings and say 8-11 for the 2 level (depending on vulnerability of course). It might be best to retain 2♥/2♠ as loose preempts (especially the latter) and use only 2♣/2♦ for the 8-11 type hands. The 1♣ - 1♦ GF idea is good, but I would recommend using one of the several semi-positive structures discussed in several threads on this forum. The 1♣ - 1N bid doesn't convey anything useful and that purpose is better served by a lower level bid (say 1♣ - 1♥). It would be useful to further specialize the 6-7 (5-7) responses into hands with one or both majors etc. Quote Link to comment Share on other sites More sharing options...
straube Posted February 17, 2010 Report Share Posted February 17, 2010 akhare's right. After 1C-1N, opener has an impossible guess. Pass could be right, bidding could be right, and the auction is too high to relay for responder's pattern. spotlight7's right. No bid for 0-7 with no 5-card suit. The NT rebids after opening 1C...is that only after a 1D response? If so, those rebids chew up a great deal of bidding room. If it's meant after 1C-1M, 1N...why do you want to play 1N with 16-17 when you can pass responder's 5-card major when he's shown 0-5 hcp? How does opener force after say 1C-2D? He might have Axx AKQxx x Kxxx and want to bid 2H nf or he might have AKxx AKxxx A KQx and want to bid 2H forcing. 1C-1D GF is used successfully. It saves a lot of room. You need to save a lot of room when responder has bad hands. Like 1C-1H as 5-7 and 1C-1S as 0-4. Or you could just play 1C-1D as your 0-7. Most of these solutions give both hands extra chances to bid. Quote Link to comment Share on other sites More sharing options...
