As I understood the "renegative double," it was sort of a concept similar to good-bad or a maximum overcall double (never understood that terminology), in the eraly days before people came up with those alternative solutions. Also, it was strangely limited to the specific instance of a negative double by Responder -- why is a mystery. But, nonetheless, the idea was that in this very auction, a double by Responder having shown hearts, and spades raised by advancer, the double was used to distinguish a weak raise to 3♥ from a strong raise to 3♥. Which was weak and which was strong I cannot recall.
That idea then got expanded by a lot of people who play Montreal Relays to have Opener also make negative doubles ater the 1♦ response and intervention. However, that is really just an Opener's negative double. The "re-" in "re-negative double" means that the double happens twice, meaning open-overcall-double-advance-double.
The utility of this approach has lost some merit, IMO, in that good-bad works better after spade intervention. In the event of heart intervention and a leap (1min-1♥-X-3♥-? or 1min-2♥-X-3♥-X, it has merit but is really a specific instance of maximal overcall, specific as to level of intervention rather than as to Responder's first action.
I also think it has merit in the context of a two-suit negative. Thus, for example, after 1♣-1♦-X-3♦, 1♣-2♦-X-3♦, or 1♦-2♣-X-3♣, a double by Opener operates as a way to show some fit (unspecified yet) with a different range than naming the fit. However, this also is alternatively an expansion of the maximal overcall double, perhaps.

The actual hand would have bid 3♥ without the 2♠ bid, so now I will bid 4♥ (as a transfer to 4♠X
But if you want to agree with partner that Dbl shows a hand too good to bid 3♥, I guess that is playable. But what are you going to do with the good 1345 hands, then?

Thanks for the info as I had not seen it before

I don't agree with the argument that good-bad 2NT solves the problem of distinguishing different heart raises. After
1♣ 1♠ dbl 2♠
2NT 3♠
responder can't effectively judge whether to bid on, because he doesn't know whether there's a heart fit or not.
As usual, transfers are probably better than either of these methods.
Regarding nomenclature, the prefix "re-" implies repetition, so it ought to refer to a sequence like:
1♣ 1♠ dbl 2♠
pass pass dbl
If I were looking for a linguistic abomination to describe the double by opener in response to a negative double, I'd choose "co-negative".

It does work, if the 2NT bid shows a heart fit (good or bad, ur choice).
With diamonds, you could just bid diamonds, since you have 2 levels and 5 diamonds is so far away, but u are not likely to have enough diamonds to do that anyway, after opening 1C.

I don't usually quibble about terminology, and I know that nomenclature varies across the world, but I've never heard anyone use the term "good-bad 2NT" to mean a 2NT bid that shows a raise. It's possible that that's what Phil meant, but I rather doubt it.
Also, in the first line of the post of mine that you quoted you'll find the sentence "I use 2NT by opener as a good 3♥ bid", so I'm not quite sure who you think you're disagreeing with.

Thanks for the posts to date. Is there a consensus here?
DBL = Solid opener likely 3 card support
2NT = Minimum or Good opening with 4 card support
3♥= Solid opener with 4 card support
Did I get it right?
If so, 2NT does not solve the problem with this hand. Responder will sign off in 3♥ fearing the minimum raise.

sometimes you just have to roll the dice. When you do you try to play the odds as best you can figure them.
