1nt 15-17

2♦ 18-20 BAL

12-14 BAL is opened 1♣

 

So 1♣ shows 5 clubs in unbalanced distribution or 12-14BAL or 4441♦.

1♦ is unbalanced or 5332.

1M is 5 card.

 

Over 1♣ opening transfers. Accepting a transfer shows a three card support.

2/1 after 1M opening is GF except rebid. 2c can be balanced with only 2clubs. Over 1♠ 2♦ shows ♥ and 2♥ shows ♦. Kaplan Inversion.

 

Questions:

-WJS or SJS. Or reverse flanery?

-What do you think about playing Checkback Stayman (2♣=want play 2♦ or invit, 2♦=GF) after 1♣ opening and accepting a transfer to major

-After 1♦-1M play 1nt as 12-15 without 3card support and 2♣ can be any hand with 3card fit. And continuations? Or do you have idea how use 1nt rebid?

-1m-1x/2nt shows nat. 3m bid without 3card support. Or bad 6m?

-1m-1x. I like splinters here.

-1♣-1♦/1♠ and 1♦-1♥/1♠. Forsing or not? (2♠ splinter?)

-After minor opening the new minor rebid can be a very strong hand with fit (5422- if I have splinters) or 6m. Is it a good idea? And what now?

-Over 1M opening play mini-splinters (inv+). Balanced GF is bid vid 2♣. 2nt is invit with balanced hand.

-Do you have any other hints?

 

Thanks

In these 2♦ systems with 18-20 bal, I always wonder what 1m-1Z-2N is. What do you intend to use it for?

In 14-16 context 2d=18-19 and 1x=1y=2nt=exactly 17, then use fancy Baron over it or 2 way checkback, 3c=game only, 3d=slam somewhere. Please note no game invite sequence over 2nt=exactly 17.

 

Using offshape 1nt and 2D will help limit your one level opening bids to a more managable subset. Just as strong club opening does.

I use 1m-1M-2NT as huge old raise of the major. Misho and I termed this J2NTO for Jacoby 2NT by opener. Our responses are:

3♣ = I have no interest in game (or I have strong slam try hand)

3♦ = ok, I am willing to bid game, but not excited about it.

3♥ = (even if hearts was the major) = slam try, tell me aobut shortness

3♠ = I am short in other major,

3NT = splinter in minor opener didn't open

4m = where m is openers suit, strong slam try, second fit

4om = strong slam try, second suit.

 

Over 3♣ (no game interest), opener can rebid 3♦ to re=invite. This means responder can reject and then re-evaluate in terms of a second invite. So some 7/8 point blah hands can reject and then accept.

 

This also narrows the meaning of 1m-1M-3M, and as a consequences, narrows the meaning of 1m-1M-2M too. But not sure all this is useful if 1m is limited to 15 hcp or less (precision stuff).
