I play 11-14 NT with one partner. We play opener's rebid shows 15-17. Questions:
1) With the NT rebid being strong, would you recommend that the sequence 1m-1M-1NT-2OtherMinor be:
a) Forcing and natural, showing ?+ points
B) Not forcing, showing a weak 2 suiter, as in Standard American methods
c) Some type of NMF or Checkback (specify preference and details)
2) We play that a second rebid by opener (i.e. 1H-1S-2C-2S-2NT) doesn't show 15-17, and is probably a minimum opener. Is this appropriate?

Hi, I play a treatment that can be very good for your 11-14 NT since it's specially designed for 3hcp-wide NTs.

After
1c-1d;1NT we play our NT structure as a normal 1NT opening but now in 15-17 range.

After 1m-1M; 1NT I play a double checkback with a twist

2c: Any invitational hand or signoff in 2d, opener must bid 2d and now
responder passes or bids naturally with an invitational hand. If
responder bids 2NT it's a "solid" invitation (about 12-13) HCP and
we expect pd to go to 3NT with a good 12hcp hand or any 13-14
hand.
2d: Game forcing (any) opener rebids as in nmf
2M: Signoff
2om: Less than invitational values 5-4 hand
2NT: Light invitation (11-12) HCP, opener should bid game only with good 13 hcp or 14hcp.
3m: Weak signoff
3om: Weak signoff

Hope this helps.

Hi Peter,

1. I would cleary vote for c checkback/nmf or even better: Play 2 Club as artifical and 2 Diamond and 2 Heart as weak and non forcing.
Put this together with Walsh and you have a quite modern approach to the one level openings.

My prefered method is called "Relay transfers":

After
1m 1Spade
1 NT 2 club:

2 Diamond normal relay
2 Spade: 3 card support

After 2 Diamond:
Pass to play
2 Heart: Inv. with 54 majors
2 Spade Inv with 5 spades
2 NT Inv with 5 Spades
3 Club to play
....
3 NT pass or correct to 4 Spade

Without the 2 Club relay:
(Again after f.e.
1 m 1 Spade
1 NT:
2 Diamond:to play
2 Heart 5-4 majors pass or correct
2 Spade to play
2 NT inv. with 4 Spades
3 Club strong GF with Clubs
3 Diamond GF with D
3 Heart 55 Majors GF
3 Spade 6 Spades GF
3 NT to play with 4 Spades

You can get some more features, so we had defined some more bids, but otoh we never really used them.

2. I guess the given sequences 1 H-1S-2C-2S-2NT
should show something very special. But Unluckily, I am not able to see, what.
But I don`t think, that this should show a weak semi-balanced hand. Because with 12-14 and 2524 you can just pass 2 Spade.
I think the minimum bids are: PASS or 3 Club and maybe 3 Heart. But anything else should be strong.

Kind Regards

Roland

Thank you Luis and Roland for your comments.

You both recommend using 2D as NMF. I gather that there are different approaches to it.
Does it always guarantee that the responder's major bid at the one level is at least 5 cards?
What relay sequence do you recommend?

I use the two way checkback on

1x-1y
1NT-?

Where
2C --> forces 2D, and if responder bids again, its game try
2D --> artificial game force


1H-1S
2C-2S
2N

Should not be weak, balanced semibalanced, as you should either open 1NT or pass 2S with that hand.

No, as I said I play 2d to be ANY GF hand, opener is expected to bid 2M with 3 card support, 2OM with 4 cards or 3m with 5 cards (3om with 2344) 2NT with 4333 (4m). Then it should be easy to coninue naturally. Yes I said that :-)

that looks good. But do you play anything like that after 1x-1y-2NT?

Also if responder has 5 hearts and 5 diamonds weak and it goes 1C-1H-1NT-2C, should opener puppet to 2H instead with 3 card support and only 2 diamonds as would rather play there than 2D.

Thanks

Try googling Wolff Relay, IIRC it's 3 as a puppet to 3.

The problem with breaking the puppet to 2 is that partner might have been about to show an invite with five hearts. What does he do now? In this style responder could be 64, so 2 could still be your best spot.

Ok, so how are the following different:

1D-1S-1NT-3S

1D-1S-1NT-2C-2D-3S

1D-1S-1NT-2D-2H-3S

1) 6 card slam-try
2) 6 card invite to game
3) Good question! Probably a hand wanting to hear more about partner's shape before showing the 6 card slam-try - not that I would expect it to come up, mind! In my methods (is it standard?) any 4333 would rebid 2N over 2D, so even playing Better Minor opener has promised 4-4 in the reds.

1D-1S-1NT-3S

Invitational with a 6 card suit

1D-1S-1NT-2C-2D-3S

GF with a 6 card suit - but see the sequence below

1D-1S-1NT-2D-2H-3S

Categorically sets S as trumps and is RKCB

IMO better than 2 way checkback is transfer checkback - a structure I have already mentioned in previous posts viz
1D-1S-1NT-2C - puppet to 2D, varios weak or invit hands
1D-1S-1NT-2D - transfer to H, weak or gf+
1D-1S-1NT-2H - transfer to S
1D-1S-1NT-2S - strong, slammish and asks for partner's distribution
