1H--1S (nat, rel)

2NT--3NT (4522 SJS, soff)

[Zelandakh]

Could you add my result - 3NT(S) - to the outcomes list please straube. I notice that on both this hand and the last there are several missing (IMPrecision is missing on Hand 8 for example).

Pass 2000 (north opens):

 

2C - 2D*; (2C shows 8-11 hcp, 5+ clubs unbal without 4+ major, 2D is GF relay)

2NT - 3C*; (2NT shows single-suiter with spade shortness (may be 6322 with 2 spades, 3C Relay)

3D - 3H; (3D equal shortness, 3H relay)

3S - 3NT; (2-2-3-6, 3NT to play)

 

I must say that I'd rather bid 2H over 2C, to see if north has 3 card support for hearts. We've however changed this from INV+ (forcing) to INV (non-forcing) since we play a GF relay. 3NT might not be wise either since diamonds may be troublesome. On the other hand diamonds would be troublesome in 5C too. 4H may be playable if partner has a honour to help my suit.

Playing a version of SCAMP, a Moscito variant:

P I would pass with an A on the side; partner would open 3C

. 1C 16+

2S 8+, 0-2S, 6+C

. 2N relay

3C 2-2-3-6 or 2-3-2-6

. 3D relay (3-level breaks NAT, initially for a choice between that suit and 3N, but not appropriate here)

3H 2-2-3-6

. 3N N's pass suggests a hand unsuited to a 3C opening, so usually a weaker C suit, and not strong enough to open 2C (10-15). But 3N seems best: give N the SJ and HJ and a D stopper and we might not need C as a source of tricks.

 

This would be much harder if N were not a PH as a 3S relay takes us past 3N when teller has 6 or more QP (3N=5, 4C=6 etc). 3N would risk playing there opposite hands as good as xx xx AKx KQJxxx as teller needs 9QP to resurrect over 3N. Opposite an UPH I think asker would bid 4D, which asks teller to bid 4H with a min and, with better then min (so 7+QP here), to bid his cheapest suit where he doesn't have a good suit (Hx, HHx/HJx[xxx]). Now we'd play 4H.

Molybdenum Forcing Pass System:

North has to open with this system, as pass shows opening count.

N ---- S

3♣ --- 3♥ (weak, forcing)

3NT --- P (signoff)

 

It's pretty self explanatory. :)

Got any questions about this, Zelandakh? :ph34r: B-)

 

Of course, if you FORCE North to pass... and cooperate with the system...

 

N --- S

P --- 1♠ (opening count?! --- GF anything)

2♣ --- 2♥ (natural bids)

3♣ --- 3♠ (natural bids)

3NT --- 6NT!! (diamond stopper, cowboy blast opposite supposed opener)

Except for 6NT, not bad :blink:

[Zelandakh]

Got any questions about this, Zelandakh? :ph34r: B-)

None whatsoever. But I do have a suggestion. There have been quite a few threads recently discussing the use of an artificial 3♦ response to a 3♣ preempt. One example is here. It is not a high priority in system design imo, indeed I even suggested the simpler way in the linked thread, but when you are going to so much trouble with system design then you may as well incorporate this too if you find the idea a good one.

 

So, for example, if you play the version which asks Opener to bid the cheapest major where they do not hold a 3 card fragment, then you have the auction: 3♣ - 3♦; 3♥ - 3NT instead. This not only helps with right-siding 3NT, it also allows Responder to differentiate between 5 and 6 card major advances as well as providing a slam try in clubs.

Unnamed Homebrew Diamond:

N may decide to open 1♣ (nebulous), in which case:

1♣-1♠ 10-15, no 5cM, unbalanced/any 15+, establishes a GF

2♣-2♥ Natural, minimum, denies a 4cM/5+cards, natural

3♣-3♠ Still minimum, waiting/showing a stop

3NT To play

 

If N is feeling frisky, he has a 9-11 NT available:

1N-2♦ 9-11 "balanced"/transfer to ♥

2♥-3♠ No 4-card support/second suit, GF

3NT To play

 

If N passes:

P-1♦ 16+, non-GF

1♠-2♣ 8+ almost any/single-suited ♦ OR both majors OR short ♣

2N-3N Suggestion of NT/to play

 

So any way around, we play 3NT by N.

I do not understand this auction. Why is the ♦A not an ace and how does South know to find a diamond stopper opposite? Any reason North could not be 2326?

3 Controls = A + K or 3Ks. The diamonds can not be solid (3NT response initially), thus responder has an A or K outside diamonds. It could be the A♥ and then 3NT is down, or it could be the A♦ and 3NT makes, however, slam appears to be very low probability. Sometimes you just have to guess.
