Can someone explain the responses to Multi 2 diamond opening bid (6 spades or hearts)

7-10 HCP. and opener's rebid?

Also I learned opening bid of 2 H =5hearts + 5 of one of the minors 7-10 HCP

2S= 5 Spades +5 of any other suit 7-10 HCP . I don't see many people using this. What is it called and what are the response.

Thanks

Basic responses to Multi-2♦ (variations not uncommon)
2♥ = I want to play in 2♥ if that is your suit (may get excited if you correct to 2♠)
2♠ = I definitely like hearts, but not spades.
(over either of these, 2N by opener shows the big balanced hand if that is an option)
2Nt = asks for clarification
... 3♣ shows max with hearts
... 3♦ shows max with spades
... 3♥ shows min with hearts
... 3♠ shows min with spades
... 3N shows the big balanced hand

The other openings you asked about are usually called Muideberg (I don't really know the continuations).

Dutch revolt here! Muiderberg (note the extra R) is on 5-card major and 4+minor and never both majors. What you describe are "Polish 2-suiters".

About Multi you can get into a big discussion if 2♦ - 2♠ actually shows strength or if it can be bid preemptively. For me it can.

Other responses to Multi:
3♣: Natural forcing
3♦: Natural forcing
3♥: Pass or correct
3♠: Pass or correct
3NT: To play
4♣: Bid the suit below your major
4♦: Bid your major
4♥: To play, you probably have ♠ but I don't care
4♠: To play, you probably have ♥ but I don't care

And there are many ways of responding to the 2NT thing...

What sort of hands bid 3 of a minor instead of 2NT?

[Double !]

Question/pregunta:

How good of a hand does advancer (responder) promise, if anything, if advancer responds/bids 2NT, and what types of shapes might advancer have? (2♦-p-2NT?) One could count the number of times that I've played multi on a few fingers, so i am not exactly an authority on the matter.

Too bad multi is mid-chart...................

I've been playing Multi on and off for more that 20 years.

The response structure I favour is:
2♥=pass or correct
2♠=pass or correct, with a maximum 2♥ show a feature a minor suit
2NT=asking
3m=natural and forcing
3♥=pass or correct, preemptive with support for both M
3♠=natural, slam invititational
4♣=ask for transfer to your suit
4♦=ask for suit
4M=to play

Over 2♦-2NT:
3♣=maximum weak 2; 3♦=ask, 3♥=♠, 3♠/NT=♥
3♦=minimum w/♥: 3♥=inv
3♥=minimum w/♠: 3♠=inv
3♠=strong bal w/5c♠
3NT=strong bal, not 5♠
These last two doesn't apply if the Multi only can be w2M.

I strongly recomend that you can't have ♥ as sidesuit when opening 2♠.
Responses to 2M 5c + 4cm+:
2♠=natural, decide if it's to play/inv/GF
2NT=strong ask
3♣=pass or correct
3♦=pass or correct, might chose to use this as some strong conv. bid
3M=preemptive raise

Responses to 2M-2NT:
3m=natural, minimum
3♥=maximum with ♣
3♠=maximum with ♦
After 2M-2NT-3m, 3M=inv
After 2M-2NT-3x, 4 in openers minor is slammish in this suit, other new suits is cuebid agreeing the major.

You can use this as a framework to add to.

2NT shows at least game interest. Otherwise you respond 2/3♥.

The Multi convention can be used at any level in Norway, and are extensively used in most clubs here.

After 2NT, opener must not bid his suit since that woukd tend to wrong-side the contract. The Norwegian scheme as described by Scaeran is fine. The Dutch scheme is
3c: min with H
3d: min with S
3h: max with S
3s: max with H

That depend's on at what level you want to play.

You can't play at the 2-level, since the 2♠ response is pass or correct, and that's the meaning you'll need to have - because of frequency.

The 3♠ response could/should be natural. I'd not like to use it as "to play" - again because of frequency. But that also depends on what meaning you apply to the sequence: 2♦-2NT-3x-3♠.
If 3♠ here is natural (and forcing of course), then 2♦-3♠ should be non-forcing. I'd then prefer it to be invitational. If 3♠ in this sequence is a cuebid agreeing ♥'s (when that's partners suit), 2♦-3♠ is needed on hands where you'd like to make a natural GF in ♠'s.

If you want to play in your own major suit at the three level then bid that suit at the two level, which is pass/correct. Partner will correct and you then rebid your own suit at the three level.

♥Full 3 way Multi and Weak 2 suiters (in NZ they are known as weak Tartan 2's), we play this in conjunction with 4 card suits at the 1 level and 12-15 NT.

2♣ Acol, absolute game force, or 23-24 balanced, 2♦ relay, if rebid not 2NT then game must be reached.

2♦ 3 way multi, either a) weak 2 in ♥ or ♠ (6-10hcp) OR 8-9 playing tricks in 1 or more suits (i.e. just less than a game force) OR 20-22 balanced with 5332 shape.

Responses to 2♦:

2♥ - pass with weak 2♥ or bid 2♠ with those. Any other rebid shows the appropriate strong option. After the 2NT strong rebid, 3♣ asks for the 5 card suit.

2♠ - Shows GAME interest opposite a good weak 2♥. Pass with weak 2♠, evaluate a weak 2♥ opening, or show the strong options.

2NT - GAME try relay. Reponses:

3♣/♦ Good weak 2 in ♥/♠
3♥/♠ Poor weak 2 in ♥/♠
3NT upwards - the strong options (rare but pleasant when they occur)

2♥ - weak 2 suiter (6-10hcp), 5+♥, 5+other suit

Responses to 2♥:

2♠ - pass or correct, pass with ♠ or bid minor
2NT - strong relay, bid 3minor if min, 4minor if max, 3♥ min both majors, 3♠ max both majors

2♠ - weak 2 suiter (6-10hcp) 5+♠, 5+minor

Responses to 2♠:

2NT - strong relay, bid minor, jump if max
3C - pass or correct to 3♦

2NT opening 21-22 hcp, NO 5 card suits (note the extra point required for no 5 card suit)
