How much does opener need for her rebid?
(I'm going back to read the thread on reverses yet again)

Oh, these auctions were deliberately excluded during the discussion on reverses. Mike, we need another thread. Please!

Not showign your 4 card M isnt a problem since with 10-11 5m4M partner suppose to bid the M so if he got 4M he is 12+ and can bid 3M over 2NT.
The problem is that if 2NT shows 12-14 responder with 11-12 hcp will have to guess wather he should pass or bid 3NT.

1♦:2♣
2♦ poor hand, minimum
2nt good 13-14
2♥/♠ forcing but could be min 5♦/4M
3x game forcing

2D, minimum, unbalanced, NF (could be a 4441 shape)
2M: unbalanced, GF (14/15+)
2NT: 12-14 balanced, NF, doesn't promise stoppers
3C: 4+ clubs, NF
3D: GF, 6+ diamonds
3M: splinter in support of clubs
3NT 18-19 balanced

With all due respects this is totally illogical. Why is it harder to find a 4M fit? After a 2D rebid responder simply bids her Major. What IS poor imo is if the reverse does NOT show extra values. How can you possibly show extra strength in the minimum slam zone area?

If 2/1, ongoing debate, but I expect responder to very often have the stronger hand so I just rebid my shape even with a dead minimum. In your example 5-4 shape, no extras promised, can be dead minimum.
Responder assumes I have a minimum at this point.

Mike, when you play this is 1D-2C forcing to game?

Long one suited minor invite hands are the system hole.
At the table we bid 1nt or 2nt with those.

No way I am missing slam if I got 17-18 as opener and partner makes a forcing 2/1 bid. As I mentioned I expect responder to have the bigger hand very often.
Partner does not make a 2/1 on a normal 13 hcp. That is only an invite hand for us. (see system hole)
Keep in mind opener dead minimum that partner assumes can be:
xx...AJxx...AJxxx...xx
If I got 17-18 I have an easy bid on hand.
As I said those playing sayc can explain how they do it.

The SAYC documents are actually somewhat ambiguous about the 2NT rebid; there are clear indications that 2NT can be a minimum, that 2♣ is the normal bid by responder with a game-invitational balanced hand and no major, and that 1♦-2♣-2NT is forcing since responder promises a second call.
It seems most playable (to me anyway) to have a simple rule that in a 2/1 auction, opener should never bid past two of her original suit unless holding game values; and rebidding two of the original suit does not promise extra length or shape. Under this approach 1♦-2♣-2♦ could still be a three or four card suit, and 2♥,2♠,2nt,3♣ are all forcing. I know this is the way Eddie Kanter used to play back in the days when not-always-game-forcing 2/1s were more popular in expert circles.
As to what one would assume in a pickup partnership, it's anybody's guess.

The rebid issue after 1♦ 2♣ is a theoretical quagmire in standard methods. Established expert partnerships usually develop special agreements for it. I know of several approaches: Richie Riesig has a good one. My preference is actually close to what JB suggested.
I use the 2♦ rebid by opener as essentially a noise: it may well only be on a 4 card suit, if opener is unable to make any other call within the confines of the method. This is, obviously, less than perfect, but there is no perfect, simple method here.
2Major is about a King more than a minimum... so, say a working 15 count, and guarantees 4=5 or better shape.
2N is balanced, with both majors stopped, and at least 2♣s. It does not deny a 4 card major, but if we have one, we are 4432 shape with a weak notrump hand.. this way, if responder reverses into a 4 card major at the 3-level, and catches opener with a raise, a lot is known about opener's hand (and opener can cue en route to 4Major with some hands)
2♦, the catchall, is not necessarily a minimum, alho as a matter of practice it often is, if bid with only 4 or 5 ♦s.
For those who play that opener should rebid a 4 card major on all habds possessing one, some my objections have already been voiced by earlier posts.
If we are playing SAYC, then 1♦ 2♣ has not yet established a gf. We need some way of doing so, and it will sometimes be opener who has to make that announcement. Since 2♣ promises 10+ hcp, it makes sense that opener have 15 or the playing equivalent to gf.. and this is one very cogent reason why opener's rebid of 2Major should show that strength: it creates a gf. If it did not, then the partnership will often be floundering on the next round. Responder, with gf values and a strong ♣ suit, cannot rebid 3♣ over 2major, if 2major could be a minimum, since opener may pass.. so does he have to invent an abominable 4th suit forcing?? Imagine: 1♦ 2♣ 2♠ 3♥.... with 3♥ a noise... we have destroyed an enormous amount of bidding space and yet have exchanged very little information!
Now, playing 2/1, particuarly a style in which 2♣ is gf, at least eliminates that difficulty. But 2/1 has its own areas of difficulty: especially with strong but not huge hands facing equally strong but not huge hands. Thus it is not uncommon for 2/1 players to reach 3N with 16 opposite 16, when opener was offshape for 1N (if playing strong notrumps). 1♦ 2♣ 2♠.. .if responder knows that this promises extras, then he will not be afraid to probe beyond 3N... and 3N is a kind of bidding trap for bridge players with no major suit fit. If 2♠ is wide-range, then responder will be leery of reaching 4N on 12 opposite 16... yes, it may make, but the cost of going down 1 in a voluntarily bid 4N makes most of us cringe.
I could go on... but I have some work to do.

Hi Mike,
One sequence not mentioned here is 1♦:2♣ 3♣
I never see it discussed, I dont think its a great bid but I do use it with 3 card support and no other bid available.
Good, bad, terrible, does anyone use it?

The solution is to have reverses show enough opening strength to create a game force opposite the minimum 2/1 response.
The other problem is how to stop when the combined assets are insufficient to produce a reasonable game. IMO, the best solution is to assume that a 2/1 bid is forcing to 2N or 3 of opener's suit, hence responder must bid once more unless opener makes a minimum-showing rebid. This allows 4441 to open 1D and rebid 2N passably with a minimum opposite a minimum, and thereby retaining 2D as at least a 5-card suit.
One of the weaknesses inherent in SAYC is the necessity to jump bid to create game forces, wasting room, but due to the reasons for utilizing 2N as weak and passable (if you open a 12 pt weak NT 1D and get a minimum 2C response, 2N is the place to play most likely.)
The question of the 1D-2C-3C is that it should be a 1-round force - else it becomes too convoluted to play - not ideal as you may reach 4C with no play, but then these are some of the weaknesses that 2/1 attempted to eliminate - which it did, but created a whole new set of problems in doing so.
