I prefer the 2nt rebid with offensive strength hands with 10+ cards in the minors since this takes away LHO's ability to compete again at the 2 of a major level. More than anything, it depends on the bidding style of my opponents. With 4513 shape and 16 HCP, many do not play equal level conversion doubles on 4 spades, 5+ hearts. If I just rebid 2D on my 2146 hand, this allows LHO an easy double of 2D. This may lead to a making 4S by my opponents. If I raise the auction by bidding 2nt instead, there is too much danger for LHO to double.

I find either forcing or semi-forcing playable and not a real advantage to either method so I play differently based on what my partners prefer. If I do play semi-forcing nt and I hold 3 card support for partner's major with an unbalanced hand, I will fib and show a 4 card invite since I do not want to play in 1nt with distributional raise of partner's major. With a balanced 3 card LR, there is no qualms about bidding the semi-forcing 1nt.

There are many methods available to play both Bergen raises and invitational one-suiters. An example is my suggestion intitially published 26 Sep. 2012:

There are methods available for handling “Bergen raises” and invitational jump shifts in a minor. Over 1H, 3C is 4+ hearts, either a mixed raise, or a GF with an unspecified void.

1H-3C**-3D by opener asks, then:

3H = min mixed raise,
3S, 3nt, 4C = GF w/ void (low middle high, so 3S = club void, 3nt = diamond void, 4C = spade void)
4D = max mixed raise with 3+ controls (either 3 kings, or 2 aces, or one ace, one king)
4H = max mixed raise without 3+ controls


1H-3D = 4+ hearts, limit raise

1H-3H = preemptive heart raise

1H-3S = “good preemptive” raise to 4H with singleton or void on the side.

1H-3S-3nt** asks, then:
4C = club singleton or void, 4D = diamond singleton or void, 4H = spade singleton or void


1H-3nt = splinter in spades, 12-15ish
1H-4C = splinter in clubs, 12-15ish
1H-4D = splinter in diamonds, 12-15ish


1H-2S** = strong jump shift in spades OR invitational jump shift in either minor.

Over 1H-2S-2nt:
- 3C = 6+ clubs, invitational
- 3D = 6+ diamonds, invitational
- anything else = strong jump shift in spades



Over 1S, those that play a version of BART can use the following:

Over 1S,
-3C is 6+ clubs invitational
-3D** is 4+ spades, either a mixed raise, or a GF with an unspecified void.
-3H = 4+ spades, limit raise
-3S = preemptive spade raise
-3nt = “good preemptive” raise to 4S with singleton or void on the side
-1S-3nt-4C** asks, then:
4D = club singleton or void, 4H = diamond singleton or void, 4S = heart singleton or void.


1S-4C = splinter in clubs, 12-15ish
1S-4D = splinter in diamonds, 12-15ish
1S-4H = splinter in hearts, 12-15ish


- 1S-3D-3H by opener asks, then:
- 3S = min mixed raise,
- 3nt, 4C, 4D = GF w/ void (low middle high, so 3nt = club void, 4C = diamond void, 4D = heart void)
4H = max mixed raise with 3+ controls (either 3 kings, or 2 aces, or one ace, one king)
4S = max mixed raise without 3+ controls


Over 1S, if you have an invitational jump shift in diamonds, go through 1nt, then if partner bids 2C, you bid 2D (artificial BART) - any rebid by opener between 2H and 3C, - 3D = natural invitational.

If partner rebids anything above 2C after 1S-1nt, you are in the same guess as everyone else that does not play direct invitational jump shifts in a minor over 1S.

It is advisable to play 1S-1nt- 2 of either red suit by opener = 4+ card suit. Therefore, when opener rebids 2C, they could be as short as 2 if they are 5332.


Of course it is partnership decision whether to play 1nt as forcing or semi-forcing over 1 major opener.

All of the example hands given in this story are easily handled by 2/1 GF systems that use appropriate bidding agreements for treating these hand types.

Balanced 15 counts with 5 of one major and 3 of other can open 1nt.

Invitational hands with a long minor can be handled over 1 Major opening from partner. As an example, if partner opens 1H and you hold 3127 invitational hand with clubs, you can bid 2S as either a strong jump shift or invitational with a minor. In this case of course you show partner that you have an invite in clubs.

Hands that your partner opens 1S and you hold 5 hearts, 10-12 HCP, you bid 1nt, then if they continue 2C (which may be short as 2 if 5332), you bid 2D** and use whatever version of BART responses that you and your partner choose to play.

There are benfits to playing a semi-forcing 1nt response to 1 Major openers, but playing a 2/1 system, the partnership may elect to play forcing 1nt or semi-forcing 1nt. A partnership may also consider playing forcing versus semi-forcing based on type of game played (imps vs matchpoints for example).

I would expect a good 15 to 19 HCP with 4+ diamonds, 6+ clubs.

Certainly a reasonable way to play is your suggestion John. Certainly if you and your partner have made these agreements this would be helpful on the hand. My only reluctance to playing it that way would be that I may have a very powerful hand with a singleton in diamonds but I would like partner's input before deciding between 6C, 6nt, 7C, or possibly 7nt.

7C is a fair contract to reach. One possible auction would be: 1H-2C** (GF, may be short as 2 if 4342) - 3D (splinter raise in support of clubs, typically shows 5+ clubs) - 3nt (wasted king diamonds, min GF, only 3 clubs, stoppers for 3nt) - 5D (exclusion, I really like my hand for clubs plus I know that partner has to have 3+ clubs now since they did not raise hearts) - 5nt (2 keycards for clubs outside of diamonds, hence the ace hearts, king clubs) - 7C.

In order for slam to be cold, partner will need to take care of 4 of 5 cards: A & K spades, first round control in each of the other 3 suits. It is my opinion that partner should not have 4 of the 5 controls for this auction. If partner held something like: AKxxxxx xxx Axx void, I would have expected to hear a cuebid of 5D. Since partner simply bid 5S, slam is not in the cards but it is likely that we will set 6C dbled despite the distribution apparent on the hand.

Agree John that this hand that we have is an absolute rockcrusher. A part of hand analysis that many seem to have difficulty with is being able to reevaluate hands for “30 point” decks. In this case, we have an ace, a king, a doubleton, and a decent 5 card diamond holding. I too am concerned that we may be cold for slam. Given that there is no underlying description of additional meaning behind the 3D on the previous round of bidding, partner is presumably in the dark that I hold all of these values. Given that I decided to bid just 3D on the previous round of bidding, I will follow through with 4D this time.

As much as we want to bid and make a vulnerable game at IMPS, the net expected IMP outcome from bidding 2nt or 3D is a loss. If the opener has a hand that makes 3nt have a fair chance at making, you would likely want the opener to play the hand since you have no protectable values. Opener could hold Qx(x) in hearts and need to protect their hearts in 3nt. This is the potential upside for trying 3D. However, 3D will of course require opener to scramble 9+ tricks if the auction ends there and there are many layouts of hands where 3D will not be a given to make if the opener does not have a hand worth bidding over 3D.

The option to try 2nt is close to correct in terms of values (10 HCP) and stoppers in each of the suits. However, queens and jacks are very slow values and the defense will be able to setup 5 tricks many times before the declaring side can setup 9 tricks in 3nt.

Therefore, I believe that pass of 2D is the long run winning call with this hand. Of course you may adjust your choice based on factors like the state of the match. If this is a hand near the end of a knockout match and you know that your side is either up a fair number of imps or down a fair number of imps, there is more reason to make an invitational bid with this hand. Assume that your team is the stronger team and you hold a fair lead with only a handful of boards to go. You should invite with the hand and hope that your side will declare the hand at least as well as the weaker team. Therefore, you hold your potential losses to a minimum by only losing a handful of imps if you go -100 in 3nt while your teammates are -110 against 2D for example. You want to prevent the ability to have +130 at your tabel and -600 from your teammates.

If you are behind a fair number of imps you may take the push to invite with the hope that you will have a +600 for a nice IMP pickup on the board.

Pass, 2nt, & 3D all have something to be said for being the call here.

A factor that has yet to be mentioned is the tempo of my opponents and “table feel”. Even among the better players capable of working out the correct play in situations like this, there are only a small number capable of doing so in tempo and not give away anything in “table feel”.

With 64 in the majors, if my hand is good enough to take just one bid I show the 6 card major. I will show the majors if I have a hand strong enough to take a second bid. The hand given is about the minimum strength needed with 6 spades and 4 hearts. If the majors were reversed, I would just show the 6 card heart suit. If you added an extra ace or king in the 3 or 4 card suit, it would be strong enough to take a second call even at the 3 level. Therefore, with something like: KQxx AKQxxx J10x void, I would show both majors since the hand is strong enough to correct to 3H.

The hand that I gave is of course 100% for 6nt as well if you play the hand double dummy and run the jack of hearts and pin the 9x or 10x. Much prefer to be in 6C when it has a greater chance of making than 6nt and does not require finding an unusual line of play to make it.

Of course this auction isn't likely to come up very often, so not many partnerships have established followup agreements here. One idea would be to play that your first pass showed values, then your second pass gives partner options what to do next. Partner may bid 4D, 4S, or more likely they will double again. Over 2C-3nt-P-P-DBL-4C-P-P-DBL-P:

4D can be a transfer to spades;
4H can show at least 44 in spades and diamonds;
4S can show 5+ diamonds.

You can also reverse 4D & 4H and play 4H as a transfer to spades and 4D as both suits. This way of playing would wrong side diamonds.

Give partner something like: QJxx Kx AQx QJxx. Certainly a hand that many would try 3nt over 3C with slow cards and what looks like 2 possible stoppers in spades and diamonds. Over 5nt, partner will happily bid 6C. 6C is a far superior slam to be in, especially at imps. 6nt could go down if hearts are 42 with Q10xx or Q9xx behind the AJxxx and the diamond king behind the AQx.

Agree that doubling here would be a joke. I would just pass 4C also, but there is some consideration for bidding 4S instead.

Agree with rebidding 1nt here instead of 2C as the hand is a weak nt hand fairly balanced. Partner may be able to evaluate their hand as worth a 4S blast at imps vul if we rebid 1nt.

Choose 5nt here as choice of slams for partner. They may have 4 clubs still but bid 3nt as they likely hold alot of values in diamonds and may have something like QJxx in spades. Over 5nt, if partner bids 6C I pass. If partner bids 6D, I bid 6nt.

The question is do you and your partner have any bidding agreements when the opponents overcall 1nt other than dbl is penalty? Any agreement on what 3H initially would have shown? Would that show a fit showing jump or weak with a bunch of hearts or something else? If you do not have firm agreements for bids over their nt overcall, it would seem that you should have started with a double.
