And please, make a print-out of this post and read it before every bidding theory post you make. Before stating the advantages and disadvantages of a convention ask yourself whether you have really looked at all sequences affected. Also ask yourself if you have really evaluated the frequency of gain for all approaches correctly. Until you can look at a bidding system as a whole in this way, there is little point in these discussions. That would be a shame; I enjoy discussing bidding theory greatly. But it is really no fun to write a long post explaining the pros and cons of something, only to see only one side of the argument presented a few pages later as a summary or even "fact".
Wish I could do that.
I try.
But there are so many creative aspects and criteria people come up with, all of which can only be weighted subjectively, that this is impossible to do comprehensively.
Some do a more convincing job and some do worse, usually dependent how good and experienced the person as a Bridge player is.
For example you yourself wondered why Multi might be a winner at all when used directly, considering a weak two more effective and claiming that Multi's main advantage is in overall system construction freeing other bids.
There was a recent intriguing discussion on bridgewinners
http://bridgewinners...ss-competition/
which shed some interesting aspects why this convention might be effective after all and how to use it.
With regard to PS, it's advantages and disadvantages and its variants have been discussed to death. As usual there remain
the convinced
the skeptical
the ones, who do not care.
I belonged to each of these buckets at some stage in my Bridge career
