It is right what you say because indetermination for second unspecified suit in original "Astro" whilest in my variation vs 2♣ all couple of suits are known (in second round for 2♠ ambiguous) as you can see in my post #25. Than talking about two suits is better use term "Higher Suit (i.e.♦)" and "Lower Suit(i.e.♣)" (for ranking).

Other than that, I'd mostly just bid naturally against 2♣. Although I'd recommend using a couple gadgets, such as double to mean both majors and 2NT to mean both minors, if you want ways to show a few more different hands. I find these the most important since if you have a major and a minor, it's better to bid the major anyways as it'll give them less bidding room at the same level, and is the more important suit for your partner to know in 3NT defense. Honestly this is enough to cover everything I feel all that important and it seems good to use the other bids for just as safe as you can possibly get away with type of bids.
Honestly you probably can't find much because there isn't much else you can do that would help any more than this.

The aim because i address at URL in post#24, is where you can see and have already the schemes and reponses of convention that acts in the same way as Astro that is very duttile and ,combining those, are covered many bidding situations. Than if you like or think is better you can change but probably have to remanage anything.

Yes, Mathe is fairly effective and probably the best choice for the vast majority of serious I/A pairs. Many use it even at the highest level.

Let's clarify the discussion.
2♣ - ?
You want to know when should the inteventor bid? Inteventor is a made up word by bridge writers. Therefore the word probably doesn't appear in normal translations.
This is one of my favorite subjects. First to bid at the 4♣ level or higher one must be non-vul and needs at least 10 cards(6-4 or better) in two suits. Think in terms of playing tricks, not high card points. Other than an ace, points in the short suits are bad for your side.

I would like to remind you(Lovera) that many of us(posters) are over 70 years old. Posting a board in this manner gives me an headache.
Also it is better to show only one hand.
West ♠ KJ109 ♥ KQJ98742 ♦ - ♣ 5
What was the auction when this hand first had to act? Also give the vulnerability. I always assume imps unless the OP states MPs.

Than you are saying to reserve the 4th level for hands having : 1)a long suit (7/+) plus a suit with four cards for 7/8 winners or 2) a one-suiter hand (8/+) for 9 winners? It can be. About the word "intervenor" i think it is a term indicating the bidder starting convention.

interventor- is the player overcalling.
advancer- is the partner of the interventor.
The first bid can be natural or conventional. Opponents open, the first player of our partnership to bid(not pass) is the interventor.
After opponents open 2♣ strong, only consider a 4 level bid if both non-vul AND holding at least ten cards in two suits. Mainly you have a max of 3 losers in the side suits. In general when vul don't even bid on the 4 level unless you can make 10 tricks in your own hand.

You are of a winner more than me restricted. Although if opp cannot bid slam but only game partner surely will have one or two cards covering losers.

Neither bidding nor vulnerability is known for it. After 7♦, West defending with 7♥ takes South to 7NT instead double (factible on ♥ K lead).

My view is to NEVER preempt vul whenever opponents open a strong 2♣. Also rarely preempt vul whenever opponents open a strong 1♣.
At this stage - first application of a new subject - you can think to insert restriction of any type (i.e. shape :5-5 instead 5-4 and/or vulnerabity: white and/or points :10/+) remembering that when you analyzed hands let try to find "rules" if to apply or not by-passed hands also when you are red (if it is possible).
