♥ seems clear.
I do not like your scheme for showing specific numbers of tricks in
♥ after opening 2
♣, altho in fairness, proper assessment would require knowing the entire structure. Anyway, you were not asking for that type of comment
I think that one should try not to open 2
♣ with purely offensive hands, for several reasons.
On this type of hand, there is no realistic chance of the auction going 1
♥ P P P
So you will always get a chance to bid again. And should they blast in a black suit, you are certainly reopening at all conceivable levels: I would not pass if it were 6
♠ around to me!
If you open 2
♣, the opps will bounce at least as fiercely as they would over 1
♥, and you are a tempo behind in showing your shape: now, maybe
♦ is not the correct trump suit, but there will be hands on which partner needs to know that you have an extreme red two-suiter.
Also, if you open 2
♣, you will almost never be able to trust partner should he decide to make a penalty double later on. Indeed, he will often be making a penalty double not on defence but on a lack of cards: your 2
♣ opening will convert many of his pass situations into forcing passes. A 2
♣ opening should announce ownership of the hand: with this hand, you have no clear reason to think that this is not their hand in 6
♠!
If you open 1
♥ and later bid some large number of
♦, and he, silent until then, doubles the opps, you can pass safely, since his double will be a positive statement, not an ambiguous call.
Finally, I would not choose my constructive bidding approach on the basis that my opps will pass hands on which some others might bid.
