Another simple auction for Meckwell-Lite with QPs:

1♣ - 1♦ (16+; ostensibly 0-7 or 0-4 QPs)
1♠ - 2♦ (4+♠ F1; 5-7ish 3 card raise)
4♠

[awm]

Borderline hand for north; I tend to treat these as semi-positives in IMPrecision because it limits the hand (and it tends to be easy to make sure we reach game).

1♣ (16+) - 1♠ (balanced or diamonds)
2♠ (min, spades and a minor) - 4♠

C3: Copious Canape Club

1♣ - 2♦ (8-11 balanced)
2♠ (SAB-3) - 3♣ (3+♠ & 1-2 Controls) -
3♥ (CAB) - 3♠ (No 1st or 2nd round control) -
4♠ p p p

[rbforster]

Silent Club:

P-1♣
2♣-2♦ diamonds 1 suited; weak relay
3♦-4♦ 3352 GF (~8-11); end relay
4♥-4♠ forced; signoff

Remember north is a passed hand, no need to investigate too much.

[Trick13]

1♣ - 2♣ [16+; 8+ with 5+♦]
2♠ - 3♠ [5+♠; 3+support]
4♥ - 5♦ [1st/2nd round controls in ♣, ♦, and ♥; 1st/2nd round control in ♦ not ♣]
6♠

West leads a ♥, and I end play him with the K♠ after eliminating the minors, East having pitched a ♦.

IRL I will probably subside in 5♠ (I'm a vegetarian).

We need to play SAB but how do you find a 4-4 side fit?

The first SAB is a 3-cd ask, if negative reply, then a second SAB is a 4-card ask. Asking again in the second suit (assuming negative reply) is a 3-cd ask - that's how Keylime and I play.

North opens 1♦ in Molybdenum.

1♦ - 1NT
2♦ - 2♠
4♠ - P

1♦ = 0-10, 4+ diamonds
1NT = Forcing, asks
2♦ = 7-10
2♠ = Forcing

Pass 2000

North opens:

1♠-2♥ [8-11 balanced, no 5 card major; transfer to spades]
2♠-3♣ [normal transfer accept; natural GF]
4♠

Dubbelklubba (our version of Swedish Club)

South opens:
1♣-2♣ [11--13 balanced or 17+; 8+ (so about 8-10) hcp with 5+ diamonds]
2♠-3♠ [natural strong; support]
4♠

[yunling]

quite standard
1♠-2♠
4♠

[antonylee]

Same for Polish.

[whereagles]

Two-way pass:

pass 1♣
1♠ 2♠
2NT 3♣
3♦ 4♦
4♠

pass, 1♣ = 0-8 or 15+
1♠, 2♠ = nat 15-20, nat 4-7
2NT = unspecified short suit trial
3♣ = waiting bid
3♦ = singleton
4♦ = ace across, and a max
4♠ = hands mesh, but that's probably not enough...

If opener is an optimistic bidder, this would end up in 6...

Pass-1♣ (meh ; 16+ any)
1NT-2♥ (8-10 bal ; transfer 5+♠)
2♠-3♠ (accepting trf like after a NT opening ; GF with 5♠ and doesn't want partner to play 3NT with fit)
4♠-pass (3+♠ ; ok)

We play our NT structure over 1♣-1NT. Definitely not the best idea, but it's easy on the mind and lets an unbalanced hand describe (if he wants to). Opener could also show his ♣s (2NT) after which responder would bid 3♦ showing a ♠ fit. Now opener can show his ♦ shortage with a 5=3=1=4. But imo opener is too weak to start looking for slam unless responder can superaccept.

The South hand is close to the boundary for a strong club. With 7 controls upgrading seems to be the right decision though, and besides this auction is (slightly)more interesting than 1♠ - 2♠ etc, since it makes North declarer:

1♣ = 15-17 nat/bal or 18+ any
... - 1♦ = most non-GF hands
1♥ = 18-20 any or 23+ bal
... - 1♠ = most hands
2♠ = 5+ spades, 18-20
... - 4♠
