Infact in Astro Defense Method is used it and i thought can be a mistake (="intervenor" instead of "interventor") - The Astro bidder (Intervenor) promises nine cards in two suits -

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.

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

For what has been told till now we can say that: the hands at second level are ruled as in Astro bidding mechanism; at third level are one-suiter hands with 6/+cards weak or the hands more strong that cannot bid directly at fourth level lacking any condition (to rebid then); directly at fourth level as indicated in post #48 (or equivalent shape) with a solid long suit. You can also gain if, not winning bidding, the other line remain off a better contract or them don't double.

Vulnerability and bidding is critical to the decision making process.

 

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).

When, in first round, starts the conventionated bidding you must have almost in one of the two suits so indicated an Ace or a King. As first opp is also to consider your favoureble position about top honors and conv. can be used when you are the second opp (i.e. 2♣ - p - 2♦ - X=the second opp shows ♦+♠ suits). I want remember what told for original Astro: "The Astro bidder (Intervenor) promises [almost] nine cards in two suits. The high card points should be mainly in the two suits and should be stronger if vulnerable. The high card points are a matter of partnership agreement, although it is imperative that the held (working) values be mainly in the two suits indicated. The recommended values lies within the range of a minimum of 9 and a maximum of 14 points. The general guideline is that the Astro bidder hold at least two of the top five honors."
