Hopefully they'll vote first. Should I delete it?
Anyway I published the other viewpoint a week ago :)
I wonder how many of the readers guessed (or realized) it.

tell them and tell to partner. Sometimes partner can decide better too if well informed.

My partner opened 4. It went 4-(6)-P-(7)-X, thus I did not lead my singleton K, thus I scored it 2 tricks later.

I don't think that North's runout must be a weak hand, rather a distributional one, because very probably the 3N bidder (who probably psyched) will run out to 4.

South should have either passed the double or bid 3N. Pass is mostly lawful versus 3 or 4: cca 16/17 total trumps are expected and the heart KQ is wasted in offence. 3N is not clear by the law: we guess 16 total tricks. If they are 7+9 or 9+7 then we should bid, otherwise we should pass.

Timo, it clearly won't matter much if we can't make anything, but regarding that they were green vs red it was pretty much possible that they had nothing outside clubs (or much less than their actual holding).

Let's give partner Kx, Qxxxx, Qxxx, xx.
What would you like to play? How can you get there? And he can have more spades and less hearts and you still will be in 4.

Don't you think that North may hope for, but not really expect partner's pass with his singleton spade?

70, because I am careful as responder / advancer :)

Is 4 after this 3N a control bid or choice of games? If control bid, then I can't see any problem. If natural, then west should have bid it instead of 4.

Edit: I would have opened 1, the hand is OK for a 3 rebid.

My software (using relay precision) bid it this way:

1♣: 14+ hcp, 8.0+ plt, 16+ tp or 16+ hcp
1♥: 8-12 hcp, 4+s, h <= s or 8-12 hcp, BAL, 2-4h, 2-4s or 8-12 hcp, 4414 + 4405
1♠: relay - sGF
2♣: 4+s, 4xxx + 5x7x + 5xx7 + 5008 + 5080
2♦: relay
2♥: 5+c, 0-3d
2♠: relay
3♥: 4135 - shape3h
3♠: slam try+, 0-7th, 0-7ts - rangeAsk
3N: LR - rangeAskL
4♣: 8+ tc, ace ask - RKCc
4♥: 1 keycard or 4 keycard - RKC14
4♠: Queen of trumps? - spiral0
5♦: +cQ +sK no dK - after spiral
7N: 13 tricks, 1 ruffs

So, if you play a good system, you don't have to be so intelligent, even a stupid computer can bid it :)

Opener can of course have more hand types, but I think that responder's bids are very similar, arent't they?

The poll is about the sequence in the diagram, i.e. reopening with a double then jumping to 3.
I would appriciate your thoughts about the other options.

An example is http://hanglemezek.hu/csabi/1s.bid">here (1 opening, plain txt file):

Opps' bidding (if any - not yet) are in parentheses, their passes can be omitted.

Recognized “keywords”:
s, h, d, c: length of the 4 suits
ts, th, td, tc: total length (own + min promised by partner)
qs, qh, qd, qc: suit qualities
plts, plth, pltd, pltc, plt: playing tricks in each suit and total
hcps, hcph, hcpd, hcpc, hcp: HCPs in each suit and total
tp: total (HCP + distributional / dummy) points together
control, Qt (= queen of trumps), ace, keycard, void
LR/UR/TR: strength for limited hands (lower / upper / top range)
min / extra: strength for unlimited hands
weak / inv / GF / slam try / ace ask: total strength of our line (own + promised by partner)
LS, HS, LV, HV = lower / higher shortness / void (at 2 suiters)
[] = distribution. The classic precision 2d opening is [3415 + 4315 + 4414 + 4405]. A classic precision 1-1NT is [any 4333 + any 4432 + any 5332 - 5xxx - x5xx].

Full disclosure on BBO is another machine readable format.
Mine is both machine and human readable (at least for geeks).

Yes, thanks, you must be right :-) - I corrected it, anyway.

I fear to confess, but I've been doing the same for 25 years professionally (and another 8 years before graduating), and still make mistakes :) (in bridge too)

Currently the opponents do not bid. There is a revaluation before each bid, which will consider opps' bids too if I ever reach that phase. As I said, it is in an early state (pre-pre-pre-pre Alpha, if you prefer :-) )

I just published the deal because of the funny bidding.

It would be too much time to explain the whole thing, but in short the “MakeBid” function is not that simple… Let's say, it detects that it got an invalid bid from a called sub-function. How should it handle the situation?

I am with Frances (though not exactly with her percentages), majors are not the same. Hearts are an entirely different story, this way the poll does not make much sense.

Mostly we bid distribution regardless of stoppers, thus we can't bid soppers at all. Here we can bid stoppers if we feel like. Mostly opps can see their strong suits in their hands, they don't need to be told what to lead.

It depends on whether 2 of a suit is gameforcing or not. If it is (some people play that way) then 2 is not a good idea. If not the of course 2 (stoppers up the line) should be bid, not 2.

I don't think 6 was such a horrible bid as many of you do.
Not the best, it's true, but IMO the raise to 7 was worse. North already promised GF and 4-card . His 7 points in diamonds are known to score a single trick (sometimes none).

Small slams can be bid on general strength (especially with a void), but grands are better not. Sometimes (too) intelligent bids can lead to disaster too. (I'm not stating that this is the case here).

In ATB style 70% North, 30% South.
