From other topic:
1D-1S
2D-2H
Some play this as a GF or invitational relay.
If invitational:
- What does opener rebid with 4card H and values to accept the invite?
If GF:
- What should responder bid with an invitational hand and eg 5=4=3=1, 5=4=2=2?

PS: I started to play a new system where 1D-1S promises 4+c♥ or longer ♥ then ♠.
I have a problem with:
1D-1H
2D-2H
- 1♥: is 4+♠, can be 4=4 in M or longer S then H
- 2♥: GF relay (new suit after opener rebids his minor)
And over 1♦ we play:
- 1D-2H: 4c♠ and 5c♥, 6-9HCP
- 1D-2S: 5c♠ and 4c♦, 6-9HCP
==> Seems like these agreements make invitational hands and eg 5=4=1=3, 5=4=3=1, 5=4=2=2 unbiddable.

Thanks,
