yunling Posted September 13, 2014 Report Share Posted September 13, 2014 I'm revisiting the posts about riton 2♣ and it seems everyone has accepted that it should be combined with Roman 2M openings(2M as 12-15 5M&4+C)as Henri Schweizer suggested which I had some difficulty to understand.I would rather switch 2M opening and 1M-1NT-2M, so now a direct 2M shows a minimum opener with 6+M. Advantages:1. Showing a 6 card suit immediately is good for competitive auctions2. With a 6 card major, it is less likely for you to look for fit in the other major, while you gain some 5-3 fit in other major that are lost when playing roman 2M3. Less information leakage if the hand belong to opponents Does this make any sense? Quote Link to comment Share on other sites More sharing options...
ritong Posted September 13, 2014 Report Share Posted September 13, 2014 hello yunling imo, showing two suits at once is better regarding competitive auctions- we all know that many expensive boards are generated by wrong décisions with undisclosed double fits- this rejoins your third point yes, more informations to opponents if hand belongs to them i m not sure this can be avoided. regarding 5/3 fits in other major, the responder can have a complete picture of the opener's hand via a 2NT relay, including 3514 shape. friendly henri Quote Link to comment Share on other sites More sharing options...
mgoetze Posted September 13, 2014 Report Share Posted September 13, 2014 Would you also want 1♥-2♦; 2♥ to show clubs? What would 1♥-2♦; 3♣ show? Quote Link to comment Share on other sites More sharing options...
benlessard Posted September 14, 2014 Report Share Posted September 14, 2014 2M is way safer with 6M than with 5M+4C and its not close at all. Its also got a higher frequency and more premptive power (easier for partner to raise) and its less likely to lead you to a bad partscores in uncontested. No brainer imo.

snillrik13 Posted September 16, 2014 Report Share Posted September 16, 2014 2M showing 5-4+ in M/!C is essential playing imps and Gazzilli. Much easier to find crucial games and slams. Also as Ritong says less sensitive for preempts. Playing match Points maybe weak two is better. Quote Link to comment Share on other sites More sharing options...

yunling Posted September 16, 2014 Author Report Share Posted September 16, 2014 Would you also want 1♥-2♦; 2♥ to show clubs? What would 1♥-2♦; 3♣ show?A natural GF 2♦ is not a part of my system, but if I'll play that, my idea is2♥ = bal or 4+♣2♠ = natural2NT = 6+♥3♣ = 4+♦, then 3♦ is non-serious3♦ = 5♣ Can't put all 1-suited hands in 3♥, that's too high.

mgoetze Posted September 17, 2014 Report Share Posted September 17, 2014 Also, what would you do with 6 hearts and 4 spades? If you open 2♥, you can miss a 4-4 spade fit. If you open 1♥, responder bids 1NT, and what are you going to do now if 2♥ shows 5♥4♣? Quote Link to comment Share on other sites More sharing options...

If you open 1♥, responder bids 1NT, and what are you going to do now if 2♥ shows 5♥4♣? For every 41??/51?? vs 46?? you will get the same amount of ?1?3 vs ?6?4 where 3C will be bad, but at least you are one level lower and you don't have the 5??3 vs 3514/3505 to worry about. The best is simply to play KI and use 1NT as artificial instead of 2C. 1H-1S-1NT 1NT could be Gaz,Riton or transfers etc.. it doesnt really matter, almost anything will be better with 1NT art than with 2C as art.

If you open 1♥, responder bids 1NT, and what are you going to do now if 2♥ shows 5♥4♣? KI can help here. Inquiry 2/1 also use a version of Kaplan Inversion.So1♥-1♠-?1NT = strong2♣/2♦ = natural2♥ = ♠ 1♥-1NT-?2♣ = strong2♦ = natural2♥ = ♣ Quote Link to comment Share on other sites More sharing options...
