What agreements do people have against Gambling 3NT opening, assuming a standard running minor suit with no outside ace? Do they vary depending on which seat bids it?

Absence any agreement how would you approach this hand:

R v W, teams.

♠AK87 ♥KJT93 ♦AQJ8 ♣Void

(3NT) ?

It struck me that whilst I know which suit the bidder has partner probably doesn't have a clue so a double could show the majors or it will just add confusion and could be a disaster at these colours. On the other hand if we pass we could be missing a nice vulnerable game or even a slam.

As always, thanks in advance for your comments,

If you take all 13 tricks, that's +450 against your vulnerable game: you should not pass out a gambling 3NT at these colours unless you can't make a contract. Here, it looks very much like you've got a contract making.

I think sensible agreements are "double shows values" or "double shows majors". LHO will almost certainly pull this one, since even with QJxx/AQxx/Kxx/xx he doesn't know you haven't got 5 fast tricks, and that's all the unplaced values in his hand. You're then fairly well placed.

In The Abbott's Great Sacrifice, a girl's team from Southampton University plays 4C here as take out of clubs and 4D as take out of diamonds, with emphasis on the majors.

I use my 1NT defence, which is Multi Landy. So here I could bid 4♣ to show both majors(and maybe follow with 5♦).

However, the better call is probably double (just a decent hand to start with), and I anticipate making a take-out double of 4♣/5♣ as well. We could be cold for 7♦.

ML with Shogi and Manudude03. I don't think I have discussed it with other partners.

My first impulse was 4♣ followed by 5♦ but maybe Phil is right.

There is a defense against 1NT that never really got a great following, but that works very well against gamblng 3NT. It is called Ripstra.

Double: penalties
4♣: Both majors + something (Hxx or so) in clubs (i.e. "partner, their suit is diamonds")
4♦: Both majors + something (Hxx or so) in diamonds (i.e. "partner, their suit is clubs")
4M: natural, to play

It looks like it is made for your hand: The easiest Ripstra 4♦ bid ever.

The methods that I described in my book Overcalling Opponent's 1NT would work well here, as well, because of the potential need to show a two-suiter with either major and either minor efficiently.

For example, one could easily play:

4♣ = both majors or one major and clubs. Advancer picks his better major, assuming both majors, but bidding 4♦ to prefer spades. If Advancer picks hearts (4♥) but Overcaller has spades+clubs, Overcaller corrects to 4♠. If Advancer picks spades (4♦) but Overcaller had hearts and clubs, he corrects to 4♥.

4♦ = One major

4♥ = hearts plus diamonds

4♠ = spades plus diamonds

That method, then, allows all five expected two-suiters to be handled efficiently, as well as all one-suiters. (You could reverse structure to make 4♦ one major plus diamonds, with 4M natural.)

We play the basically the same defense against multi 2♦ where 2 of a major is takeout of the suit you bid so use 4♣/♦ for 3 suited hands here.

Double is a 2-suiter either major minor or both majors. Penalty makes no sense since they will always run. Kens approach over 1nt is good but you don't want to come in with 3 suits against a strong nt and here you do. Maybe it would work fine if you used Double to show those hands?


And 1 suited majors bid it. The hole is a 1 suited minor that has to bid 5 or pass so we don't get dealt those hands.

Yes -- you can double with three-suiters or with canapé hands (major with longer minor usually 4-6)

If you have 4-4-1-4 or 4-4-4-1 and partner picks a major, great!

If you have 4♠ and a longer minor, and partner picks spades, great!

If you have 4♥ and a longer minor, and partner picks hearts, great!

If you have 4♠ and a longer minor, and partner picks hearts, try 4♠ as a spade-MINOR canapé.

If you have 4♥ and a longer minor, and partner picks spades, bid your minor.

If partner tries 4♣, bid 4♦ with 4-4-4-1 or your major with 4M/6♦

If partner tries 4♦, bid 4♠ with 4♠/6♣.

If partner tries 4♦ and you have 4-4-1-4 or 4♥/6♣, try 4♥ and then correct to 5♣ with the latter (or just bid 5♣ with the latter directly).

If partner has no major of 4+ length, btw, he may well decide to pass the double. So, he usually has one if he bids.

[ggwhiz]

And partner can stall with 3nt over a double as a reverse kind of lebensohl to show positive slam type values for whatever you are headed for.

[gnasher]

A multi-way defence doesn't work very well if they bid five of a minor over it. I think it's better to play
4♣ = one-suited in hearts, or hearts + a minor
4♦ = one-suited in spades, or 5-4 majors
4♥ = 4-5 or 5-5 majors
4♠ = spades + a minor

so that opener's major, or his longer major, is always known.
