In this reverse sequence where we define responders 2NT as weak
1C-1S-2H-2NT

How does opener show extra strength with longer clubs ?

---

And in these cases where opener has 2NT available after the weak bid
1C-1H-2D-2S
1C-1S-2D-2H

Is the 2NT rebid forcing ?
How would you bid a hand with extra strength but insufficient values in the 4th suit - e.g. you hold xx Qx AKQx AKQxx

---

Does anyone combine Ingberman principles with what might be termed fast/slow aspects of Lebensohl.
i.e. where responder makes an unexpected rebid other than weak sign-off (bidding slowly), then do you incorporate that distinction into the understandings ?

TIA

I prefer:
- 2nt by opener NF
- if opener has a GF opposite a min, they can bid 4th suit forcing artificial if unsuitable for a 3nt rebid or other jump rebid
- if responder bids other than 2 of his M or the (potential) weakness signal, it's just natural GF.
- jump by responder to 3nt is 12-14 (slam inv only vs opener's stronger hands); 2nt by responder if it is also the weakness signal (intending to pass opener's original suit or sign off in opener's 2nd suit) can also be nat 8-11 (intending 3nt rebid) or 15+ (intending 4nt+ rebid). If there is 4th suit available below 2nt then 2nt is just 8-11/15+.

Thanks Stephen.
I will work through and see if that fills most of the holes.
