Looking at my file notes, I found this same problem from a different Message board about 8 years ago.
It was suggested for the Diam case :
1D - 1S
2D - 3D = GF with only 4 cards ♠ and concern about ♣ .
Note that Responder can't have 4 cards ♥ either because with 4-4 he would have bid 1H first .
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Likewise for:
1D - 1H
2D - 3D = GF with only 4 cards ♥ and concern about ♣ .
If Responder also had 4 cards ♠, he would have reversed into 2S .
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
The Club case doesn't have a rebid "space" problem :
1C - 1M
2C - 2D! ( cheapest bid new suit forcing analogous to NMF over a 1NT rebid )
BBO论坛太好了,这也是我一直的心病,看到世界各国的高手们的意见,让人大看眼界,感觉自己真的很初级,知道的看到的总是那么一点点皮毛而已.....
关于此类话题,我总结出三类主流意见:
第一是TWO4BRIDGE意见:
1-关于
♦再叫的建议:
1D -
1S
2D -
3D = 逼局,只有4张
♠,对
♣ 担忧。
注意:应叫人不可能有4张
♥,因为果如4-4高花,那应叫人应叫的是1
♥首先。
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
2-同理可证:
1D -
1H
2D - 3D =
逼局,只有4张♥,对♣ 担忧。
如果应叫人也有4张♠,他会逆叫2♠
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
3-关于
♣的序列,就不存在再叫的空间问题。
1C - 1M
2C - 2D! (2
♦ 是最便宜的新花逼叫,类似于再叫1nt后,应叫人的新低花逼叫。 )
第二是lowerline的意见:

This is what I play:
1♦ - 1♠
2♦ - 2♥ (inv+ relay)
Then:
2♠ = 4crd ♥ (2nt or 3♦ next can be passed)
2nt = 6♦ max GF
3♣ = 6♦4♣ (3♦ next can be passed)
3♦ = 6♦ min NF
3♥ = 4♥6♦ GF
3♠ = 3♠6♦ GF
The issue with the invitational major 2suiter remains of course. But you have already given the solution for those.

这是我的叫牌方式:
1
♦ - 1
♠
2
♦ - 2
♥ (邀请+接力)
那么:
2
♠ = 4张
♥ (应叫人再叫2nt or 3
♦ 不逼叫,可以pass。)
2nt = 6
♦ 高限,逼局 。
3
♣ = 6
♦+4
♣ (应叫人再叫3
♦ 不逼叫,可以pass。)
3
♦ = 6
♦ 低限,不逼叫。
3
♥ = 4
♥6
♦ 逼局。
3
♠ = 3
♠6
♦ 逼局。
第三是以fluffy,phil和3ntmk为代表的意见:
Phil, on 2013-January-18, 17:34, said:
2♥ is the standard solution. 4♦ is also possible.
A few non-standard:
1. Include 4cM's in your inverted minors.
2. Play 3♦ here as a one round force.
3. Start with a Rexfordesque 2!c.
Fluffy, on 2013-January-22, 06:42, said:
I would always take 4♦ as a slam try.
I would bid 2♥ and then 3♦ as a forcing raise, specially playing MPs,
世界大师fluffy意见:
我会永远把4♦ 作为满贯试探。
而我先叫2♥,然后再叫3♦ 作为逼局性加叫。

先应叫了1M后如何显示对同伴低花支持,我不太清楚。但这个进程可以跳到4D表示强的支持,同时也是低花木。
