Re: "Extolling the virtures.... "
If playing 2/1 GF ( and I'm not sure OP was ), why respond 1♠ when you have a perfectly good 2♦ bid .
If you have a 4-4 Sp fit, you will find it since a 2♠ rebid by Opener will show 4 cards but not necessarily reverse strength ( in most cases .... unless you have a special treatment to show extras ).
In this case:
1H - 2D!
3H ( sets trump and demands cuebids ) - 4C ( cue, denying a Sp Ctrl )
4NT ( RKC; partner has already denied the ♠A ) - 5H ( 2 - ♥Q )
6C! ( 3rd Rnd Ctrl-ask; partner has already shown the ♣ K ) - 6H ( don't have it )
pass
I think the idea of suggesting that we have a 'perfectly good 2
♦ bid' in the B/I forum is unsound.
It may be a debatable idea for the A/E forum or the non-natural forum, but when someone posts an ATB post in this forum, they are entitled to have the discussion focus on mainstream methods.
We have seen a number of threads extolling the notion of what is essentially an artificial 2
♣ response to 1M, but even that is not mainstream and doesn't belong in this forum. Expanding that to 2
♦ is weird, and calling the unorthodox call 'perfectly good' is misleading. Some B/I's might be given the mistaken impression that this is a normal approach.
In addition, it isn't even that good an idea, imo.
After 1
♥ 1
♠, 2
♥ unambiguously promises 6. After 1
♥ 2
♦, 2
♥ for many is neutral as to length, so we have wasted bidding space unnecessarily.
And 1
♥ 1
♠ 1n is always a better start than 1
♥ 2
♦ 2N
And 1
♥ 2
♦ 3
♦ isn't a start we want to see if opener is allowed/compelled to do this with as few as 3 cards in support.
There are other negatives as well...even if you play that opener's 2
♠ doesn't show extras....and that is NOT universal.....having to bid 3
♠ on a 4-4 hand leaves partner, who is now at a high level in the auction, not expecting a 4432 shape....I mean, how would you have bid with 4=5 or 4=6?
