There is not much in Grootheim book about auctions other than relays.

When playing 1♦-1♥ = 4+♥, 6+H or GF all distribution, how does responder invite after 1♦-1♥-1NT since 2♣ is GF relay ?

I think of using 2♦ might be the solution to show 10-11H and asking for 3 cards ♥ and strength:
2♥ = 3♥, minimum
2NT = 2♥, minimum
3♣/♦=3♥+5♣/♦, maximum
3♥ = 3♥, maximum
3NT = 2♥, maximum

Therefore, we loose the natural 2♦ fit which can thus be found via 2NT over 1NT as puppet for 3♣ with either weak long ♣ or weak shapely ♦ fit.

Any comments ?

It's been a while since I have looked at the book, but how about using 2♦ as the GF relay and using 2♣ as a puppet to 2♦? You can then play in 2♦ and describe a variety of hands including:

Direct 2♥: Sign off
Direct 3♣: Sign off w/ long ♣ and 4♥
2♥ via puppet: Inv
3♣ via puppet: Inv w/ long ♣ and 4♥
etc...

I don't think moving your relays up one more step is a good idea... Just jump or make 'impossible bids' to invite, sometimes you'll go down 1, most of the time you'll get away with it.

With my f2f partner we played something similar. 1♦ opening was 10-15 without a 5 card M (so 0+♦), 1♥ was 4+♥ OR inv+ relay! Sometimes we had auctions like 1♦-1♥;2♦ (singlesuited ♦)-2♠ which is invitational with ♠s... We usually got to the right contract.
