  3. Any 4-4-4-1 shape with 17-24 HCP

Responder's available bids are:

Opener's responses to the artificial 2NT query are:

2 Weak hand, does not promise heart support. Opener can rebid 2 should he hold hand type 2).
2 Inviting game in hearts if that is opener's suit, but signoff if opener's suit is spades. Opener can rebid 3 (signoff), 4 (signoff), or Pass with spades.
2NT Strong and artificial (see below).
3 7+ clubs, signoff.
3 7+ diamonds, signoff.
3 Hand inviting game in spades, if that is opener's suit. Opener can rebid 3 (signoff), 4 (signoff), or Pass with hearts.
4 Strong clubs with support for both majors.
4 Strong diamonds with support for both majors.
3 Weak two-bid in hearts, good hand.
3 Weak two-bid in spades, good hand.
3 Weak two-bid in hearts, bad hand.
3 Weak two-bid in spades, bad hand.
3NT Strong three-suited hand (17-24 HCP) with a singleton club.

4 Strong three-suited hand (17-24 HCP) with a singleton heart.

If responder makes an original signoff bid, any strange-sounding rebid by opener shows the strong three-suited hand.
