How about if West opens a weak 1NT, Kungsgeten?

Weak NT is very uncommon at the club we tend to play this system. We haven't discussed balancing by a pass opener after they open 1NT, but if we play our general agreements (the weak hand can not act, the strong hand must act) and our normal weak NT defense (basic Landy) it would go something like this:

P - (1NT*) - P - (2H**); (1NT 12-14, assuming they play transfers.)
Dbl - (P*) - P - (2S); Dbl shows hearts, I guess we really should have five, but what to do? I guess their pass would show only two spades?
P - (P) - 3H - all pass

If they play 2M as natural, it becomes even more awkward:

P - (1NT) - P - 2S;
Dbl - (P) - 3H - all pass (perhaps it would make sense to play Lebensohl here, but we do not have any agreements on that)

[Zelandakh]

I think the more common defence to a double of a transfer is for bidding to show 2 and passing to show 3. After a pass, many play XX as a re-transfer and bidding the major as an invite.

Your defence is also interesting. Most pairs either play X = hearts and 2♠ = takeout or X = takeout and 2♠ = Michaels. I would have thought South should be able to make some sort of takeout bid over 2♥.

In any case, it looks like all paths lead to 3♥(N) here.

[antonylee]

For me it'll be a simple strong NT-stayman (if 2♦, will bid 2♥)-2♥.

[Kungsgeten]

Zelandakh: Yes, we do play that their suit is for take-out (I just forgot), and that would probably be a better bid.

North ♠ T972 ♥ 87643 ♦ T5 ♣ K4: __ 1♦ 2♦
South ♠ Q8 ♥ AQT2 ♦ AK73 ♣ Q65: 1♣ 1N 3♥

• 1♦ = Art, neg, 0-7,

• 3♥ = Nat, 4♥.

Marks, IMO: 2♥ = 10. 3♥ = 8. 4♥ = 6. 1N = 5.

One more comment that West is not going to pass over an artificial 1C.

In Unassuming Club:
1C-1D
1NT-2D (15-18 balanced / xfer)
2H-P -- or, perhaps 1C-1NT-2C-2H, depending what agreement you have about responder's 2M after 1NT-2C-2D. In my one regular AUC partnership, it would be invitational, so just transfer here.

In Malfoir, a fun hand:
1D-3H. (11-18, exactly 4 hearts, any other shape / To play.)

North doesn't HAVE to jump to 3, 2H is also to play -- but 2H is typically 4-7 and often only 3-card heart support.

IMprecision:

1♣ - 1♦ (strong; 0-4 or bal GF or 7+RP)
1N - 2♦ (17-20 bal; transfer)
2♥

We play a form of Stayman where 2♥ over 2♦ would be artificial and not weak with both majors, so responder cannot look for a ♠ fit safely here.

How about if West opens a weak 1NT, Kungsgeten?

*** I'm with 1NT on this one. Expect a scramble to 2C.
*** Maybe even 2S over their 2H, with 3C runout.
