[navit]

I learned multi 2 d opening= 6 card major 7-10 hcp. I am a bit confused about partner's reponses and openers continuing bid. Can you please clarify in a simple manner using examples T hank]

[lowerline]

A possible set of responses (there are many):

2♥ = to play opp ♥

2♠ = to play opp ♠

2NT = forcing relay (usually 14+hcp)

3♣/♦ = natural invitational

3♥/♠ = pass/correct

3NT = to play

4♣ = ask for transfer in partner's major (so you play it)

4♦ = to play in partner's major (let him play it)

4♥/♠ = to play with own major

 

The continuation mostly speaks for itself. After 2♦-2NT:

3♣ = non-max ♥ --> 3♦ asks further

3♦ = non-max ♠ --> 3♥ asks further

3♥ = max ♥

3♠ = max ♠

3NT = AKQxxx

2NT from partner means a strong hand, and requires from you to announce your strength and your suit. The idea is that at the end of the bidding your hand will be the one that is pretty much known, not to mention weaker, so it would make a better dummy than a declarer's hand. With that in mind here are your answers:

 

3♣ - weak (7-8) with hearts

3♦ - weak with spades

3♥ - strong (9-10) with spades

3♠ - strong with hearts

 

Note how the last two bids reverse their meanings in order for your hand to be put at the table.

Partner's responses are

2♥: "if you have hearts, 2♥ is enough. Please shut up for the rest of the auction if you have hearts, no matter if opps interfere or not. If you have spades, please bid 2♠ if your RHO passes or doubles but otherwise just pass. If you show spades I might or might not make a game try or a competive raise."

2♠: "if you have spades 2♠ is enough. Please shut up for the rest of the auction if you have spades, no matter if opps interfere or not. If you have hearts, please bid 3♥ or whatever artificial follow-up we have agreed on, unless your RHO bids above 3♥. If you have hearts I may or may not make a game try.". Some partnerships play that this 2♠ relay promises game interest opposit hearts so that opener can bid above3♥ if he has hearts and extras. Some play the responder may only be interested in compeeting to 3♥.

2N: Game invite or better no matter if opener has hearts or spades.

3♣/♦: Many different meanings of those bids are around. Discuss with p.

3♥/♠: Pass or correct. This is based on a not too strong hand with in principle at least 3-3 in the majors (3♠ should be 4 hearts and 3 spades since it forces opener to bid 4♥ if he has hearts.

3N: "Don't look at your hand, just pass. I may have a solid minor suit, I may expect to set up your suit, or I may be psyching".

4♣: Asks opener to transfer to his suit.

4♦: Asks opener to bid his suit.

4♥: Some play this as asking opener to correct to 4♠ if he has spades, some play it as long hearts and no interest in opener's spade suit. Discuss with p.

 

After 2N, opener shows his suit in some artificial way so that responder becomes declarer. Different partnerships hace different agreements, so discuss.

 

After interference:

2♦-(X)-pass: "I want you to play 2♦. Don't bid your suit".

redbl: Discuss the meaning of this with p.

2♥/♠ etc: discuss the meaning of all this with p. It is certaibnly not obvious that it means the same as if opp did not double.

 

2♦-(2M)-X: Some play this as penalty, some play it as pass or correct. Some play it as P/C on hearts but penalty on spades. Discuss.

2♦-(3m)-X: Penalty.

2♦-(3m)-3M: Pass or correct.

2♦-(3m)-4♥: This is pass or correct, even if 4♥ would have been to play without the interference.

[inquiry]

I don't like 2♦-pass-4♥ as pass correct. Often enough I am dealt a bunch of hearts and want to play in game in hearts even if partner has spades.

 

If you use a strong 2NT type hand in 2♦, then i like the following...

 

3NT = 4-4 in majors, preemptive. Partner corrects to his major, unless he is strong, in which case he can pass

 

4♣ five hearts, four spades, preemptive

4♦ five spades, four hearts, preemptive

4♥, still to play even if opener has spades.

 

If you do not include the strong 2NT type hand, the responses shown by helene_t seem ideal.

If 2NT is at least invitational, this is superior:

 

3♣: Max, unspecificed major*

3♦: Weak with hearts

3♥: Weak with spades

 

* Over 3♣

3♦: Which major?

3♥: Spades

3♠: Hearts

 

This way responder becomes declarer whether opener is min or max.

Roland, isn't that also true the way he suggested playing it?

Maybe after 3♣ he can bid 3♥ as pass or correct and stay in 3♥?

 

Not sure if that is nonsense, a hand that wants to play game ONLY opposite a maximum in spades can bid 2♥ instead of 2NT.

I thought most versions of the The Multi-2♦ include a big balanced hand type?

 

The response structures I'm seeing in this thread do not seem to be catering for it?

[Gerben42]

The point is that you do not cater for the strong variations, they will show up as you go along :) The way you find out to NOT bid 2♦ - 3♥ on a weak hand with fit is to look at your opponents. If they look bored because they have a balanced 5-count, dear partner has 23 balanced.

 

Some pairs (like many Poles) play weak-only Multi.

 

BTW to Helene's post:

 

2♦ X Pass = I've got ♦, if you have some support, 2♦X is okay.

2♦ X XX = I've really got ♦, even if you don't have much there, pass!

 

As opponent / partner of a NV Multi, watch out for:

 

2♦ p 2♥ p p = I have ♥, OR: I'm just pretending to have ♥ for now but I really have ♠.

If you are playing against competent opponents or are using screens, attempting to make bidding decisions based on the opponents expressions is not likely to work out well...
