North could use regular stayman but imo this is the right way to bid since it is unknown if declarer has 4 hearts or not.

SCREAM bids this as...

1C-1D 16+, GF, unbal with major OR bal
1H-1S bal OR spades, bal OR H/C
1N-2C bal, bal w/ major
2D-2S asking, 4 spades
2N-3H asking, 4243
3N-

Long auction for us. We can't relay break for opener to show a balanced minimum so we tell the opponents dummy's exact shape. Responder has no extra so no super-accept past 3N.

Silent Club:

1♣-1♠ strong; GF bal or clubs
1N-2♠ relay; bal with 4=2 majors
2N-3♣ relay; 4243
3N-P

Given opener's min values and lack of a major suit fit when he hears 2S, he could jump to 3N there without disclosing any more of dummy's shape info.

[Zelandakh]

I have been playing around with the relay break structure for 15-17 hands after a positive. Nevertheless, this auction is essentially unchanged from the original:-

1♣ = 15+ nat/bal or 18+ any
... - 2♥ = bal with 4-5 spades and 2-3 hearts, GF
2NT = 15-17 bal (4 spades possible)
... - 3♣ = asking about spades/diamonds
3♦ = 4 diamonds, <4 spades
... - 3NT

[antonylee]

Too weak for a Polish 1♣ so will be using a regular SNT system here.

Hilversumse Klaveren

1NT - 2♣
2♦ - 3NT

1NT = balanced, 16-18 HCP
2♣ = Stayman relay (3♣ would have been asking for 4 or 5 card M; GF)
2♦ = no 4-card major
3NT = that's it

[hrothgar]

1♣ - 1♦ 1♦ = art GF
1♥ - 1N 1♥ = opener prefers to ask (balanced hand) 1N = balanced or 4441
3♣ - 3N 3♣ = Reverse Relay (44 in the minors) 3N = to play

Originally, opener prefers to asks rather than show with his balanced hand
After the 1NT response, opener reverses the relay to limit strength and conceal the 1NT bidder's hand.

3♣ shows 4-4 in the minors. Relaying out shape doesn't seem to add anything, so captain placed the auction.
(Life could be ugly if opener has 3=2=4=4, however, I doubt 5D would be any better given the limited strength of the two hands)

Using a fairly basic strong club with reverse-cuebids, I would bid

1C - 1N
3N - P

Translation:
S: 16+, N: 9+ balanced, no 5 card major, GF
S: 16-18 balanced, no 4 card major unless 4333, N: lets play 3N

[Free]

1♣-1NT (16+ ; balanced 8-10 or 13-15)
3NT-pass (balanced 17-18 without interest in Majors)

Remark: usually responder won't have a good 5 card M. Opener can ask anyway, but it's a waste of time imo. If he asks, he does so with 2NT and responder will bid 3♣ denying a 5 card M.

Richard,

From a design perspective, why didn't Moscito choose to show balanced hands with 1♠? One option might be 1♣ - 1♦ - 1♥ - 1♠ to (say) show balanced or ♣.

My guess is that it's because there probably isn't enough room, but was wondering if there was some other consideration...

Yeah. It would let opener spin of the 5440s as well as declare NT. My guess is so the structures would be mirrored.

The auction

1♣ - 1♦
1♠ - 1NT
2♣+


mirrors


1♣ - 1♦
2♣+

[FM75]

OCP

1♣ - 1♠ 8+ balanced GF
1N - 2♦ relay, 3 controls
3N - no slam interest, no interest in major suit game.

[awm]

IMprecision:

1♣ - 1♦ (strong, double neg or various GF)
1NT - 2♣ (17-20 bal not offshape, stayman)
2♦ - 3NT (no major, to play)

Looking at all four hands I'd rather north declare, but single dummy this is very unclear.

This puppet stayman thing is interesting. Comparing:

1nt-2c-2d-3nt vs 1nt-3c-3d-3h-3nt

It seems on the surface like the first auction gives more info (you know opener has no major rather than just "not four spades"). But the second auction actually gives some info too (you know which major responder has) and it also gave 4th hand the chance to double 3h for the lead. Seems unconvincing to me, and playing puppet there loses the 3c bid for an alternative use. The method of 3c puppet does seem popular in the US expert crowd though.

We use a version of Puppet Stayman for our opening NT that Klinger uses. I think RM Precision does something similar.

1N-2N is puppet stayman
.....3C-no 5M, not 4333
..........3D-4H
..........3H-4S
..........3S-13(54)
.....3D-any 4333
..........3M-4OM
.....3M-5M

With 4/4 in the majors, responder just uses Stayman

What I like about this is that it hides opener's hand pretty well, they can't double the 2N bid for a lead, there is no point in doubling the common 3C rebid by opener since that opponent is on lead, so only sometimes will they be able to double when responder tries to show that he has one (and not the other) major. Knowing whether opener is 4333 or not will help the defense sometimes and I'd rather not disclose that except that it's nice not to play mirrored hands in 4M (most of the time).

MW use 2NT as Puppet Stayman, but afaik they don't use the 3♦ response. After 1NT-2NT-3♣ they use:
3♦ = any (31)(54) (3♥ asks)
3M = 4OM
3NT = not interested in 4 card M

[Siegmund]

Unassuming club:

1C-1S
2NT(17-18)-3NT

I'm no great fan of that 17-18 leap. In my homegrown 'Malfoir':

1C-1S-1NT(15-18 no 4CM)-2C(diamonds or invitational)-2S(max, 4+ diamonds, 2 spades)-3NT
