A few words on bidding. Here is a useful approach that I play after 1m-1M-1N:

- jump above 3M in a new suit: one-suiter slam try with exactly singleton in the named suit (autosplinter)
- 2 (2-way checkback, forces 2) then jump above 3M in a new suit: similar hand with void in the suit.

This way the balanced hand can be evaluated (much) better. The actual hand:

1 - 1
1N - 2 // 2-way checkback, mostly INV, forces 2
2 - 4 // one-suiter , slam try, void in

an easy stop in 4

(Edit: sorry, others mentioned it too, I have not read the comments before writing this one)

I voted on more methods…

If you don't play any gadget then North might rebid 2N after Stayman and you make it. 9 points + 2 good tens - singleton J, I estimate it an ordinary 9 count, that is invite, but I don't really blame him for bidding the vulnerable game, especially at IMP scoring.

About the methods:
in my pet systems after 1N-2-2 we play like this, both can solve this hand

version (a): invit Smolen
2: smolen, INV+, F1
2N: INV
3: 5+, GF
3: GF, SPL, 4441 (or 5m440)

Actual hand:
1N-2
2-3 no major // 4-1-4-4 (or 4-0-(54))
4-5 can't play 3N, good hand for slam // easy sign-off, already overbid slightly
___________________________________

version (b): usual Smolen and 2 puppet
2: puppet to 2
(a) 5-4 weak hand (will pass 2)
(b) 5, INV, (near) BAL (will bid 2N)
© 4+ m, short in the other minor (3m next, opener can ask for shortness and length)
(d) 4441 (5m440) with both minors (3M next)
2: 5-card suit, NAT INV
2N: NAT INV
3: NAT, 4+ suit, short in a major (opener can ask)
3: GF Smolen

Actual hand:
1N-2
2-2 no major // puppet to 2
2-3 // 4-1-4-4 (or 4-0-(54))
4-5 can't play 3N, good hand for slam // easy sign-off, already overbid slightly

Kit, a question about advancer's bids. Let's suppose that West passes. Does your cue guarantee support in this case too? If yes: how do you bid with forcing hands that lack support? Do you play transfers?

Let's see a specific one, for example Rodwell's book.
On Amazon, a paperback copy costs 22 USD (I bought it a bit cheaper with free delivery). The same text is divided into 4 parts in the e-book edition, together they cost 25 USD.

I ask it once again. Why the printed version is cheaper? Same author, same editor. I suppose that postmen, pressmen, paper mill workers and loggers all pay a bit to make it possible. Or are they paid? Hm…

I just can't understand why e-books are more expensive than the same text printed on paper and delivered via air mail. Simply incredible and irrational.

Nice try, but dummy had only 3 trumps originally. You ruffed the third round of clubs, and 2 diamonds with them, thus no trump left to ruff your 4th diamond.

I don't think so.

RHO of course ruffs your high (or any other) spade, so you'd better lead a low one to avoid this, but if he's awake he'll ruff anyway.

If you overruff then you will finish with a diamond and a trump loser.
If you throw a diamond instead then East will lead another club and they will score West's 10 of trumps too.

Nice greek gift from East of Berkeley. On any other play declarer's only choice is the successful plan.

my 2 options were
- pass then 2N
- pass then double
in both cases I'm going to correct partner's 3 to 3.

What is the difference? I don't think any of them is likely be 5-5, with that I would have acted in the first round (well, mostly).

I guess that DBL then 3 is somewhat simlar to an equal-level conversion double, thus it should have more diamonds, while 2N followed by 3 should be more (or equal) hearts.

What do you think?

On that 4th position opening: I think 2 is better.

I prefer playing strong club too, but we all know that the weak point of these systems is the strong club opening itself. Well, it would not be if the opps would shut up :)

I disagree with the double of 2, it is an easy pass IMO. Partner would have doubled for takeout had he wanted something.

We play this one (a bit too complicated, I know):
On (1): P = 0-5, X = 5-7, system ON
On (1): P = 0-7, X = 1 response (I prefer playing artificial responses, thus it is 8-12 with 4+ or BAL in our case), 1 and up: unchanged
On (1): P = 0-7 or trap, X = 8-12 BAL or 4441, 1N: 13+ any, 2x: 5+ suit 8-12
On (1N…2): P = 0-5 or trap, DBL: 5-7 (and some 8+ with no good bid), plain bid: NAT GF, jump bid: 5-7, good suit
On (2N…): P: 0-7, DBL: GF, no clear direction (mostly BAL), suit: GF, 5+

Our 1 opening is forcing up to 1NT, thus they cannot play 1 of a suit undoubled. 2-level overcalls should be reopened if opener can imagine seeing his own hand that responder has a penalty double.

I don't like Rubensohl style responses because most often we have gameforcing response and would get too high with them, statistically we do better if our plain bids are gameforcing.

Anyway I don't mind if they make a doubled contract when they have 6-6 :)

Ren, simply cut this post and insert the suit sympols into your original article, it can be modified after publishing.

Nick, in reality (this Monday) West led low from QJxxxx, causing the whole show to happen! I modified East-West hands in my article a bit to make it more spectacular as a quiz. I was shocked to see their cards after the board (I was dummy) :).

I've got a copy of “Sytems in defence” by Slawinsky (in English, 1983, translated from the 3rd Polish edition, 1980). In this one he suggests the following - he calls it Combine:

H = A…J

A = AKx(…),
K = AK, KQx(…), AKJ(…),
Q = KQ, QJx(…), KQT(…),
J = QJ, JTx(…), AQJ,
T = Txx(…), AJT(…), KJT(…), Tx (NT)
9 = 9xx(…), AT9(…), KT9(…), QT9(…), 9x (NT)

low from xx against suit
highest non-potentially-trick-taking card from xxx(…)
3rd/5th from Hxx(…)
4th/6th from HHxx(…)

In other words:
- from HH doubleton the 2nd
- from short sequence (HHx(…)) the top
- from full sequence (HHH+) the 2nd, but may play the top
- from a broken sequence (AKJ, KDT, …): the 2nd (may play the top)
- J/T/9 is 0 or 2 higher
- small x is an agressive lead (from H or xx against suit)
- high x is a passive lead

Slawinsky proves across cca 60 pages that it's technically superior to any other lead system.

However, it is not exactly the same what you described.

It used to be popular in Hungary, some play it now too. I used to play it too but found it too difficult to distinguish xx from Jxx or similar and HHxx from Hxxxx, perhaps the former should not be a problem, because one should rarely lead from xx.

In short: when you play combine, noone will know anything surely, neither partner, nor declarer.

the other play loses only vs 3-1 trumps and Qxxx at West, which is 5.6% combined (4/10*P(4-1) * P(3-1)) = 11.4% * 49.7% = 5.6%). Or am I missing something?

Is it a better chance than 3-2 ?
