glen Posted February 26, 2012 Report Share Posted February 26, 2012 Any ideas for a response scheme after 1C-1D, where 1D is 0-7 or 13+HCP and 1C is 11-13HCP, balanced or 16+?The closest I did to that was: sob.pdf The system featured a two-way 1♣ and a negative or positive 1♣-1♦. However I was trying to make it more bulletproof by one end of each of the two-way bids as a specific hand type. A common example sequence to think about would start, with the opponents bidding, 1♣-Pass-1♦-3♣-?. Now consider what pass means here. If it just shows 11-13 balanced, then 16+ has to double or bid, and can find itself facing 0-7 without a fit. If pass is 11-13 bal and some 16+ but limited hand types (e.g. 16-18s not shapely), is 1♣-Pass-1♦-3♣-Pass-Pass-Pass the only option with 0-7, and if 13+ bids, is the partnership in a game force even if just 13 opposite 11 flat? There's some intriguing design to work on. Quote Link to comment Share on other sites More sharing options...

There's some intriguing design to work on.Well, I thought about opening positive 1♦ with 14 when flat, because then 1D opener knows, that he has GF all the time with 1C opener. Then he can always overcall or double to show that he has 13/14+ with GF. If 1C opener has 16+ points and he passed, he can now try to explore slam. That way, the only contract we can miss if oppoents do a high overcall is when weak 1D responder has enough points for a game with 1C opener, and well, that's the problem with precision too. My version - 1♣-1♦1♥ – 11-13 HCP 1♠ – 20+ HCP, 1NT – 17-19 HCP; balanced, system on2 any suit - 16 - 19 HCP, 5+ 1♣-1♦-1♥1♠ – GF, auto 1NT, responder bids he's suit.1NT – Stayman2♣♦♥♠ - transfer to the next suit, 5+ in that suit, 6+ for clubs. 1♣-1♦-1♠1NT – 0-4HCP2 any suit – 5-7HCP or 13+HCP, GF Quote Link to comment Share on other sites More sharing options...
cirenaj Posted March 12, 2012 Report Share Posted March 12, 2012 To be fair, it isn't totally unheard of. The "Tangerine Club" uses the same 1♣ opener. Not saying it's good, just that it is not quite as crazy as we have made it seem. The current European mixed silver pair, Anna Zack Einarsson and Bengt-Erik Efraimsson, are playing a Swedish club system with a 8-10 or 16+ 1♣ opening. 1♦/♥/♠ are 10-15 4+ and 2♦/♥/♠ are 5-10 5+. They mention the system and its aggressiveness as one reason for their success. Jan Eric Larsson Quote Link to comment Share on other sites More sharing options...

Cthulhu D Posted March 13, 2012 Report Share Posted March 13, 2012 Details would be nice. :) I've googled a lot, it appears that Bengt-Erik Efraimsson plays with different partners in high profile teams events so no CCs. Anyone seen one? Quote Link to comment Share on other sites More sharing options...
Flameous Posted March 13, 2012 Report Share Posted March 13, 2012 1♣ = 10-12bal/17+ - 1♦ = 0-7/14+ -> 1♥/♠ = 3+, weak NT or 4+ 17-22 unbal1NT = 17-19 bal2♣ = Big 2♣ as in natural systems2x = 6+ suit, 17-192NT = 20-213x = 6+ suit, 20+ This was a simple version me and friend agreed before we ventured to play one tournament. 1M bids are bid overloaded since they are canape or natural without 6+ and still include the weak balanced range. Of course you stick a lot of minor hands into 1NT so it's not as bad as it seems. Quote Link to comment Share on other sites More sharing options...
gwnn Posted March 13, 2012 Report Share Posted March 13, 2012 do you open 1♦ with all 2245/2254 hands? Quote Link to comment Share on other sites More sharing options...
cirenaj Posted March 13, 2012 Report Share Posted March 13, 2012 Efraimsson and Zack Einarsson plays as follows: 1♣ 8-9 or 16+1♦/♥/♠ 10-15 4+ suit1N 11-162♣ 10-16 5+ suit2♦/♥/♠ 5-10 5+ suit2N 5-10 55+ in ♦ and another suit After 1♣, the responses are:1♦ 0-7, weak opener must pass1♥ 8+ 4+ suit, weak opener may bid 1♠, 1N or 2♥1♠ 8+ artificial and forcing, weak opener bids 1N1N 8+ exactly 4 spades2♣/♦/♥/♠ 5-10 5+ suit This structure is obviously good enough that they could place second in the 2011 European mixed championships. :) Jan Eric Larsson Quote Link to comment Share on other sites More sharing options...
gwnn Posted March 13, 2012 Report Share Posted March 13, 2012 Does anyone know if transfer responses work to a swedish 1♣? Quote Link to comment Share on other sites More sharing options...
WellSpyder Posted March 13, 2012 Report Share Posted March 13, 2012 Does anyone know if transfer responses work to a swedish 1♣?I think they can work well. I use something similar, though not all are strictly transfers. 1♣ = 11-13 bal or 16+. Responses are: 1♦ = negative (0-7, or 8-11 bal)1♥ = 8+ points, 5+ SPADES1♠ = 8+ points, 5+ HEARTS1NT = 8+ points, 5+ CLUBS2♣ = 8+ points, 5+ DIAMONDS (Other responses are 2♦= 14+ bal, 2♥/♠=c4-7 points, 6-card suit, 2N = 12-3 bal - INVITATIONAL!) Over the transfer-type responses, opener simply completes the transfer with the weak hand (or jump-completes with a good fit). Other bids confirm 16+ (we use Precision-style asking bids).

Cthulhu D Posted March 14, 2012 Report Share Posted March 14, 2012 1♦ 0-7, weak opener must pass Wow, that is very aggressive. I guess if you know for sure that you have at most a 17 count, playing anything un-doubled rates to be a decent score. Except maybe if you are both maximum with short diamonds where going several off will be a disaster. Not sure I like the NT range, but obviously works for them. The same structure works for a 10-12 or 16+ 1C with a 13-15 no trump I guess. Quote Link to comment Share on other sites More sharing options...
NaeosPsy Posted April 4, 2012 Author Report Share Posted April 4, 2012 A question. 1♣(11-13 bal or 16 + unbal or 17+ any)-1♦(0-7 or 13+)-1♥(11-13 bal) 1♠ (to 1NT) 2♦(to 2S) 2♥ (to 3C) - transfers, weak1NT - transfer to diamonds2♣ - Stayman2♠ 3♣ 3♦ 3♥ - 5+, 13+HCP Or just give transfers with weak and strong hands and then continue bidding with strong hand?
