Deal #7

[Zelandakh]

1♣ = 15+ nat/bal or 18+ any

... - 1♦ = most non-GF

1♥ = 18-20 any or 23+ bal

... - 1♠ = relay

1NT = 18-20 bal

... - 2♥ = 5+ spades (implies INV+ values as no relay break last round)

2♠

... - 3♦ = 4+ clubs, GF

3♠ = spade fit, no club fit

... - 4♠

[Zelandakh]

Looking over the auctions, I do not think you should describe the 2♠ rebid as pass/correct Nige. Clearly it allows partner to show judgement since they did not pass it with spades. It seems more like a non-forcing relay to me, asking for both strength and shape. It also appears you are missing a response somewhere:

 

P = min with spades

2NT = max with minors

3♣ = min with minors

3♥ = max with spades

 

Would it not be better to have 3♦ here as max with spades and diamonds, with 3♥ as max with spades and clubs?

 

Or you could make 2♠ a genuine pass/correct bid and pass invites through 2NT. Say

 

3♣ = clubs + another, min (3♦ P/C; 3♥ GF relay

3♦ = spades and diamonds, min

3♥ = spades and clubs, max

3♠ = spades and diamonds, max

3NT = minors, max

 

or whatever. That gets you a level higher when you have a spade invite opposite a minimum pointy 2-suiter but is otherwise good. Either way, you definitely have to tighten up the definitions if playing an unusual system. Opponents need to know everything that you do (I do realise you are only summarising here of course).

In HK.

 

1NT - 2♥

2♠ - 2NT

4♠

 

Explanation:

1NT = 16-18 HCP

2♥ = transfer to ♠

2NT = 5-card ♠, non forcing

 

Opener is just one spade short to bid 3♣ in stead of 2♠.

3♣ by opner would have meant maximum hand with 4-card ♠ and 2-card ♣.

This hand much relies on responder's negative to come alive.

Over 1NT, 2-suit is quits, so jump 3C.

Jasmine Club:

North ♠ J9852 ♥- ♦ J76 ♣ AT962 -- 2♥ 3♥

South ♠ AQT ♥ K7653 ♦ AQ4 ♣ QJ 1♣ 2♠ 4♠

• 1♣ = 16+ Artificial
• 2♥ = Weak two-suiter not ♥ (2N would have shown a weak 2-suiter including ♥).
• 2♠ = Pass/correct (2N would have asked for the suit above the other shortage).
• 3♥ = Max with ♠ (2N would have shown a max with the minors).

Yes you are right

It also appears you are missing a response somewhere:

• _P = min with spades
• 2N = max with minors
• 3♣ = min with minors
• 3♥ = max with spades

Would it not be better to have

• 3♦ here as max with spades and diamonds, with
• 3♥ as max with spades and clubs?

Yes that may be better although it violates Martens Mushroom principle (keep them in the dark and feed them on ****)

Or you could make 2♠ a genuine pass/correct bid and pass invites through 2NT. Say

• 3♣ = clubs + another, min (3♦ P/C; 3♥ GF relay
• 3♦ = spades and diamonds, min
• 3♥ = spades and clubs, max
• 3♠ = spades and diamonds, max
• 3NT = minors, max

or whatever. That gets you a level higher when you have a spade invite opposite a minimum pointy 2-suiter but is otherwise good.

Introduction to Jasmine

[Zelandakh]

We try to keep everything simple and consistent because there are only three Jasmine partnerships, none of them current.

Simple and consistent is good. Without consistency a bidding system is basically doomed because it will always be too difficult to use in practise and will probably not be robust in competition. I also sympathise with the other issue. I also do not have a partnership using my system at present, although I am perfectly happy playing simple Acol instead with my current partner. The good part about such periods is that you can make changes and upgrades more quickly. The downside is that you have no practise so the changes either have to be obviously better or require a lot of time with simulators to check for negatives.

 

To be honest tough, I always love looking at unusual bidding systems and often learn something that I can use from innovative design ideas used in them. Most designers of such systems are also open to suggestions - certainly if anyone is ever insulted by an idea from me then please let me know! This will perhaps be the enduring legacy of straube's bidding project. We will get to see other systems in operation and thereby get a feel for their characteristics. I am hoping that Ben (Lessard) will also join in, since his system is especially innovative. So far, I get the feeling that my system is surprisingly natural within the context of the others being used. That is a bit of a shock to me but it is early days! Similarly for Moscito - it comes across as more of a "quick and dirty" system than the others. That is usually bad for bidding contests and good for practical play. Trying to get a feel for which of the many systems are good on paper and which are really good is going to take a great deal of thought and effort. But I know that I for one will be very interested in the results, even if they are subjective in nature.

 

Edit: I forgot to write a comment about the actual Jasmine system! It looks on the surface as something akin to 4 card major Precision, albeit with the minor suit hands moved around a little. The part that concerns me is the 1♦ opening. If I am reading it right, this contains a) 8-15 (4441); b) 8-15 minor one-suiter; c) 8-15 minor + shorter major; d) 13-15 both minors; e) 9-11 balanced (?). That is quite a lot to sort out, even if Hand Type e is not included. For example, after a 1NT response, I cannot see how you can differentiate between (primary) clubs and both minors. Assuming you have a solution for that, the rest looks solid enough. The 2♣ response (to 1♣) is obviously overloaded but manageable; and if that were ever a problem it would be easy to fix by taking out the club-based hands and moving them into a 2♦ response. Anyway, I will watch how it all works out over the course of the project!

4♠S (tosr based system)

 

1♣-1♦ : art, forcing 16+ unbal or 18+ bal; art neg, 0-7 or occ more with <2 controls

1nt-2♥ : 18-19 balanced; transfer

2♠-3♣ : accept transfer; 5+♠, 5+♣ game force

4♠ : with at most 7 hcp or 1 control slam seems remote even with the auction hitting our black suits well. I did consider 3♠ for a while which might gets us to 6♠ (3♠-4♣cue-4♦cue-4♥cue-4ntkc-6♥odd with void-6♠), but wisely decided even a near perfect fit (like the actual hand) isn't cold

Molybdenum Forcing Pass System:

S ---- N

P --- 1♣ (opening hand, 0-bad 12)

1♥ --- 1♠ (15-18, specifically not GF with 4+ spades)

1NT --- 2♣ (balanced, 5-4 in blacks with at least a few points)

3♠ --- 4♠ (super-accept of spades, signoff)

[Zelandakh]

1♥ --- 1♠ (15-18, specifically not GF with 4+ spades)

I am finding many of the explanations difficult to follow. For example, does the above mean "4+ spades and less than GF values" or "any hand except a GF with 4+ spades", that is "4+ spades and less than GF values, or any GF hand with fewer than 4 spades". The latter seems to be correct grammatically but logic and the later auction suggests the former. Similarly, the 1♣ response to an opening pass has gone from "forced" to "bad 12 or less". If you want us to follow your auctions then you need to give full disclosure - pretend we are your opponents at the table and have asked about every bid.

sorry, 1♣ shows 0-bad 12. There is another bid to show a GF hand (1♠)

Also the delayed one spade bid means that the hand is not GF opposite the 15-18 points partner has shown, with 4 spades.
