1. If 1NT deny 4M what is the meaning of 1♣-1♦-1NT-2♦-2♥/2♠?
2. What's the meaning of reverse by responder?
Responder's next bid set trump suit.
2NT: other shapes with 5♦
Opener can choose to sign off 2M/2N/3C/3D if not accepting invitation, based on the information responder gives.
Reverse shows 6♦4M
Any opinion on this?

Also I'm not sure what "only 4" diamonds is all about - I'm told some people bid 1♣-1♦ on 3 diamonds in certain situations.
Aside from the poll, my opinion is that this auction is not something worth spending a lot of time on.

After 1♣-1♦; 1NT, responder's 2♥ is either natural GF or artificial GF. Opener bids 2♠ with four card hearts. The rest of the bidding is natural.

Given that I play walsh, we have two ways for responder to gf, with a 4 card major, over the 1N rebid, which could be as full of majors as 4=4=2=3.
I think that responder should bid 2♦, artificial gf, on hands on which he feels that the best way forward would be if opener showed a major, and responder were able, with a fit, to make a slam try by bidding 3 of the major.
Shows 4=5 or better in the reds with slam interest opposite an 11-14/12-14 1♣ opening bid.
is natural and a reverse, and thus gf. Responder lacks slam interest in most cases: on slam hands, responder will by definition have a significantly stronger hand than opener, and in those circumstances, I think that an efficient approach will usually require that opener, whose shape and range is already well-defined, do the describing rather than responder, and this usually works best after responder has bid 2♦...opener is the one to start slam cooperation over 3♥, while with responder reversing, responder is the one starting the slam cooperation over 3♥.

1nt denies a major
We always bid our longest suit first over 1c.
We will often bypass 4d to bid 1M or 1nt, but not always (it depends on honor location).
Over 1nt we play either 2m as signoff in this auction.
To force over 1nt we can bid 2M, which is ostensibly natural but could be concentration of values in a minor-oriented hand. We also have 3M (splinter) available and an original SJS.

Out of interest, Mike (and others for that matter), what do you think of the method where 2♣ is "weak with diamonds or any invite", 2♦ is GF with hearts and 2♥ GF with spades?

Interesting idea, but I am not sure that it is needed.
As I suggested in my earlier post, it does seem to me that there is some utility in giving responder the ability to ask or tell: 2♦ gf asks, 2M, gf, tells. Obviously the 2♦ encompasses a wide range of hands, and doesn't imply a major, altho opener's first priority is the show a major if he holds one (and to bid 2♥ with 4=4 although I suppose one could use 3♦ for that purpose, but that's another issue).
Your suggestion appears to eliminate this approach, in that responder must 'tell'.
More to the point, using 2♦ to show hearts means that responder lacks a generic gf at the 2-level. There will usually (always?) be work-arounds for the gf hands that lack a major, but it seems to me to be an unnecessary surrender of bidding space to limit the cheap 2♦ rebid to one specific holding. Add to this the loss of responder's ability to choose to ask or tell, and force him to tell, and I don't care for the idea.

I play this as a "super-accept of diamonds" with something here. An Ace if Responder is known to be light.
♠Ax ♥xxx ♦KQx ♣Axxxx
♠xxx ♥Ax ♦AJxxxx ♣xx
2♠(super-accept diamonds, spade card)-2NT(interested, hearts controlled)
