I also thought 3♥ as inv+ with spades is NA standard.

Oh, I thought 3H was gameforcing.

That, obviously, is open for agreement.

I prefer inv+, to be able to bid 3♠ only to compete. Both approaches have their up- and downside.

good to know 3h inv+. which is the bid i am looking for. thanks for all the reply.

Scoring: IMP

1C (2N) ??
opps overcall 2n to shows diamond and heart, and N/S vul.
you are holding south hand, and what to bid ?

IMO 4♠=10, 3♦=9 (Crowhurst), 3♠=5.
4♠ is a non-forcing fit jump. 4♦ and 4♥ would be splinters.
Crowhurst improves on the (later) Unusual over unusual. Eric Crowhurst published the convention in Acol in Competition (1981). Crowhurst reverses the meaning of the 3-level cue-bids so that opener with no fit in your suit has room for manoeuvre at the 3 level

• 3♣ (Partner's suit) = Natural raise. Non-forcing.
  
• 3♠ (new suit) = Natural. Non-forcing.
  
• 3♦ (Lower ranking of opponent's suits) = Length in unbid suit. Forcing.
  
• 3♥ (Higher ranking of opponent's suits) = Support for partner. Forcing.
