1♣1♠
2♠3♣




1♠=dbl negative
2♠= transfer to clubs


jack has done pretty well only one hand where it did badly so far.

I think i will give up on qplus10 as I don't think we can learn anything from its bidding.

I think you're 2H raise is very reasonable, but the opponents on the actual deal cue bid clubs so I'd like to set the problem up that way. 3C P 3H ?

Okay, so the auction will be:

Hilversumse Klaveren (HK)

1♣ - (p) - 1♦ - (1♥)
2♣ - (3♣)- p - (3♥)
all pass

Explanation:
1♣ = 16+, not a balanced 16-20
1♦ = denying several one or two suited hands with 0-7 HCP. With 4 HCP North would have bid 1♥ = 4-4 or 4-5 in the majors and 4-7 HCP.
2♣ = natural, 5+ clubs

No action by North over Wests 3♣-bid, so no action by South either.

I am glad to have Jack participating.

Its hard for a mere human to bid these hands objectively, so its nice to see hwat a computer is able to do playing a similar system.

1♣ - p - 1♦ - (1♥) ---- if W had overcalled, north pass shows 0-4
2♣ - (3♣) - p - 3♥

Even with opposite vulnerability, I don't really have anything to say.

Not sure on this one. By system it is probably 3♥E or 4♣S. But at table we got to 4♠S.

at table:
1♣-P-1♦-1♥ : 16+ unbal or 18+ bal; 0-7 or occ 8+ with <2 ctls
2♣-3♣-P-3♥ : nat, nf (pass would have been forcing); no real special meaning for pass
X-P-4♠ : t/o; try game in spades

by system (I.e. better judgement):
1♣-P-1♦-1♥ : 16+ unbal or 18+ bal; 0-7 or occ 8+ with <2 ctls
2♣-3♣-P-3♥ : nat, nf (pass would have been forcing); no real special meaning for pass
? 4♣ or P : likely to have at least 8-9 tricks in own hand, hope partner can help

I guess the X of 3♥ is a bit too risky, especially since the hand has poor defense to offense, so if wanting to compete 4♣ is probably more correct.

If it's alright I'm putting you down for 3H by E. We're trying to take personal judgments out of this and I think your system has the same information that the other 0-7 folks have and they are all passing 3H.

Unassuming Club is going with the field:

1C-P-1D-(1H)
3C-(3H)

Opener jumps to 3C with the 16-18 hand and 6 clubs, bids 2C artificial with strong hands.

It's a weird hand for Malfoir, which succeeds in shutting out the opponents:

1C-2S

Since 1C includes 11+ hands with 4 spades, and 15-18 balanced hands, responder leaps to 2S on weak hands with 5 spades, willing to play in that spot anytime opener has spades or a balanced hand.

Now opener has to decide whether to persist with 3C (forcing, 19+) or let 2S go. I think with Jx he should let it go, as a minor-suit game requires two cover cards (and two aces is not possible) nor does 4S look easy unless you are sure responder has six.

IMprecision:

1♣ (P) 1♦ (1♥) (strong; 0-4 or bal GF or 7+RP)
2♣ (3♣) P (3♥) (less than GF, 5♣ + 4red or 6+♣; 0-4)
P (P) P

With 0-4, unless responder has honors and length in spades, we are unlikely to be missing a playable game (and responder can still choose to reopen). If this is a partial vs partial hand, we can try to see what LoTT would say. I think it's likely opponents have a 9-card fit in this auction. We may have anywhere from an 8-card fit to a 10-card fit. In the 19-card fit scenario, there is most to gain when they have 9 tricks and we have 10; in other trick combinations, the gains are between 1 and 2 IMPs. With less number of total tricks, pass will be clear. So I think pass rates to the best option.

The problem will be tougher at MP, and I would have considered bidding 4♣.

1C (p) 1D (1H) (strong, 0-7)

It is really just a judgement question on whether south should bid 4C

Molybdenum Forcing Pass System:

EDIT: Thanks Zelandakh.
This could go two ways:
S ---- N
P --- 1♥ (opening, 0-3 or 17+ with 5♠
1♠ --- P (complete transfer)

or

S ---- N
P --- 1♥ (see above)
2♣ --- P (denies spade fit and long clubs (usually 6 or strong 5))

I would probably do the second auction at the table.

Why does North not use their 0-3 bid (1♥?) on this hand? Under the conditions, that would also have the effect of preempting their overcall (since X of an artificial 1♥ response is not specified).

I didn't notice.
Fixed.

Unnamed Homebrew Diamond:
1♦-1♥ 16+, not GF / 0-7 almost any
3♣-end (semi)-solid suit, better than minimum playing strength.

Though it's not always an advantage, we get off lightly on this one by having 1♥ as our negative response!

[PrecisionL]

A bit late:

1♣(16+) p 1♦ = 0-7 (1♥) 2♣= natural, NF (3♣) p (3♥) all pass
