---> 2NT Jacoby 2NT Plus
--------> 3C, no game interest or monster slam interest
--------> 3D, Game interest, no slam interest, but better than 4M
---------------> 3H now ask partner to show shortness anyway.
--------> 3H, ask for 2NT bidder to show shortness if you have
-------> 3S short in "other major"
-------> 4C/4C short in bid suit (if not bid before naturally)
-------> 4M Just enough for game, no more
The above was taken, I think, from Glen Ashton's Bridgematters websites.

Are those steps exactly the same whether it was opened 1♥ or 1♠ ?

1♠ - 2NT
3♣ = Minimum, no voids.
3♦ = Midimum and a shortness.
3♥ = Maximum and a shortness.
3♠ = Midimum, no shortness.
3NT = Maximum, No shortness.
4♣ = Void, minimum.
4♦ = Void, minimum.
4♥ = Void, minimum.
4♠ = Minimum, but with distribution. (Usually used facing a passed hand.)
After 3♣:
3♦ Re-invite
3♥ Asks for singleton
3♠ Sign-off
3NT = Suggestion to play. (Should be changed, have never been bid.)
4♣/♦/♥ = Singleton.
After 3♦/3♥, the relay asks for shortness.
When we open 1♥, 2♠ is Jacoby, and all steps go -1.
I'm not a fanatic about this scheme, but it has served me well.
Do not underestimate the power of the dark side. Or the ninth trumph.

Some of the treatment follows:
1M- 2NT!
??
3D! = extras ( 15,16+) no shortage
3H! = extras and Cl shortage
3S! = extras and Diam shortage
3NT! = extras and shortage in other Major
Note: after the minimum reply:
3C! - 3D! ( asking for shortage )
3H/3S/3NT! define shortage in the same suits as above
And the auction can be stopped below game also:
1M - 2NT!
3C! - 3M
pass

2NT has limited types, unwound by 3♣, typically:
3♣ asks:
3♦ = 3-card unbalanced maximum limit (Opener then asks for shortness if interested)
3♥ = 3-card minimum limit
3♠ = 4441 pure splinter with 16+
3NT = 3-card max limit high controls
4bid = 3-card mixed limit (as to controls), cuebid
4M = 3-card max limit but poor controls
Opener can aqlso simply bid game, simply sign off, bid 3♦ as unbalanced slam relay, or rare other options.
This worked OK.

My concern with this method is that if responder is unlimited then a respectable proportion of the time it is going to go 1M-2N-4M and responder may still have slam interest despite opener being thus far discouraging, and you have just taken out a huge amount of space. 5M may be at risk if the hand is particularly unsuitable. This is a general criticism of "fast arrival" methods opposite an unlimited partner.

1M - 2NT = limit raise or better
----> 3M = minimum, would not accept LR, no shortness below 3M, not forcing
----> 3m, 3♥ if spades are trump = shortness, not specific about strength
----> 3♠ if hearts are trump = shortness, extra values
----> 3N = extras, no shortness, no slam interest opposite a limit raise
----> 4x (not 4M) = very serious extras, no shortness, cuebid showing slam interest opposite a limit raise
----> 4M = minimum values, no shortness, 6-7 trumps taking a shot at game
Continuations mostly as you would expect; 3M by responder shows a limit raise and is not forcing. We use non-serious 3NT to distinguish slam interest, so for example after 1M-2NT-3x responder can bid 3NT to show a game force without slam interest unless partner has extras, whereas cuebidding beyond 3NT shows slam interest even if opener is minimum. Responder jumping to 4M after opener shows shortage is an "upgraded" limit raise with a good holding opposite the short suit.

3♣: MIN or MAX, with unknown shortness (and therefore GF)
----3♦: Show your shortness, regardless of your strength (slam possibilities opposite a MIN)
----3♥: Show your shortness if you are MAX, otherwise bid 4M.
3♦: MIN or MAX, no shortness (not GF).
----3M: NF (Opener will pass or bid 4M with a MIN and cue or bid 4M with a MAX)
----3OM: Start cuebidding if you are MAX, otherwise bid 4M.
----higher: Cuebids, forcing opener to cooperate in cuebidding.
3♥: MED, no shortness (GF)
----Cuebids of 4M sign off
3♠-4♣: MED, ♣/♦/OM shortness
----Cuebids of 4M sign off
The advantage is that with a typical 13 opposite 13 hand, you will leave all possibilities open to explore for slam if partner has the needed extra's whereas you will not tell the opponents much if you only belong in game.

Sims/actuals showed that big hands best to go very slow, not even disclosing the fit (e.g. 1M-2♣ ask/relay), thus 1M-2NT denies the big hand and 4M is "to play".

1♥/♠ - 2NT
3♣ = unknown single, 11-14hp
3♦ = unknown void, 11-14hp
3♥ = unknown single, 15hp+
3♠ = unknown void, 15hp+
3NT = balanced, 11-14hp
4♣ = balanced, 15-18hp
4♦ = 19hp+

After 1♥-2NT (around 10-13HCP with 3+♥ and balanced):
3♣ = relay, asks about responder (he'll show min/max, 3/4♥, 4♠-3♥,...)
3♦ = SI, some shortness (3♥ asks)
3♥ = min, NF
3♠ = SI, strong second suit
3NT = suggestion to play
4m = SI, strong second suit
4♥ = to play
This can easily be used for 1♠-2NT as well, but you'll have an extra call available. That's why we actually use 1♠-3♣ to show this handtype instead of 1♠-2NT.

We found there are a few types of the big hands that want to show - these were embedded into the Bergen constructive raise - that is 1M-3♣ (or 3♦ if you play that as constructive) became two-way, either constructive raise with 4+ trumps or a big hand with trump support and specific hand types. Opener assumes the constructive type and usually either bids 3M or 4M, and then responder shows the big hand type by bidding again - if over 4M the partnership will have enough values to reach at least slam since opener has extras to bid 4M and responder has strong playing values having points and shape.

3♣ minimum without void or monster with void
3♦ Extras but no shortness
3♥ Extras and some singleton
3♠/3NT 5 card good ♣/♦ suit
4x void
Actually I have 3♦/♥ answers swapped in other partnership, I'm not sure which one is really better.
Our 2NT promises always inv+ and 4 cards and balancedish. It can also be done with 3 card monster hand where you just want to ask some question and choose between small and grand. Third type that can bid it is hand with shortness that could make a slam with perfectly fitting double shortness.
We had something like Qxxx AKJxx x xxx opposite AKxxxx Qxx xxxx - and after 2NT it was easy to bid the slam. We don't have fitjump in hearts which might of course do the trick also.

I've seen this and believe you also show shortness after 3m rebids the way you do with 12-14. This sucks because when you have 18-19 balanced you're at 4M and skipped all your cues...
