SUMMARY OF THE FEEDBACK RECEIVED ON THE MULTI 2♦
(from this thread and other similar threads)
ON THE NEGATIVE SIDE
1.) The loss of a natural Weak 2♦
Weak 2s in the minors are far more bothersome than many credit them for. The reason is they preempt BOTH majors, not just one. Take-out doubles over a weak 2m (or 3m) are made on 4-3 in the Majors on a regular basis, over which the risk of ending up in a 4-3 fit is considerable.
is stronger than it looks as a preempt, especially when your opponents at the other table have it available and you have to pass.
3.) The Multi should be more geared towards constructive bidding, because it has less preemptive effect than a natural Weak 2♥
4.) Multi isn't that great a convention. You're often left in the dark yourself what major partner has when the auction goes say 2♦
5.) Natural preempts are more valuable; opponents only get one chance to bid over them. They get two over transfer and artificial preempts!
6.) The majority of Multiís is a weak 2 in either major. When your major is ♠
LHO can still bid ♥
on level 2. The preemptive effect of the weak 2♠
bid is lost.
7.) The loss of partners ability to lift the preempt immediately is a big weakness of the Multi.
More often partner than not, partner is able to support only one of the majors. Not knowing which one you are holding restricts his ability to lift the preempt immediately.
8.) A Multi 2♦
is often much weaker than a Weak 2♥
9.) Many say that it is much easier to defend against than a natural Weak 2 bid. It allows for 3/4 overcall tempos.
10.) Against well-prepared opponents, it causes fewer problems than natural Weak 2s would (as they have extra room, and an extra round of bidding).
11.) The strong balanced hand type can be shown with a natural 2NT opening.
12.) Freeing up the 2NT bid to show 5-5 in the minors and 5-10 HCP has also been questioned. All you have succeeded in doing is convey the hand layout and HCP distribution to the opponents. It now makes it easier for them to balance and/or the subsequent play of the hand. Partner is marked for any required finesse in the majors, opener for any required finesse in the minors.
13.) The 4441 hand pattern with 17-24 HCP is so rare that may players of the Multi donít even bother including it into their Multi structure.
14.) The Multi 2♦

In fairness, this article did attract some criticism.
ON THE POSITIVE SIDE
1.) Against poorly prepared opponents it will probably give you a few extra good scores! Multi is said to be a net win for your side against weaker opponents.
2.) The uncertainty of preemptor's suit cuts both ways. The opponents have no obvious cue-bid in openers suit available.
3.) With the appropriate hand, partner can become declarer keeping the stronger hand hidden. The contract has been "right-sided."
4.) The "big win" through using Multi comes from freeing up the 2♥
bids for something else, the most popular being Muiderberg 2s/Lukas 2s.
5.) Muiderberg 2s/Lukas 2s are said to be effective against good as well as weaker opponents.
6.) Freeing up the 2♥
bids allows you to open more weak hands with very descriptive bids.
7.) Raising the HCP count of your Multi to intermediate strength increases the pressure on the opponents to enter the bidding or not e.g. They must guess whether to come in with a strong NT overcall in an auction where they are a level higher than the rest of the field and extremely vulnerable to a penalty double.
8.) Every bid that you use to take away room from the opponents is good.
THE FINAL PIECE OF ADVICE FROM MANY PARTICIPANTS TO THIS POLE IS THIS: DON'T PLAY MULTI 2♦
JUST TO BE PLAYING IT. YOU NEED A SYSTEMIC REASON FOR DOING SO. YOU SHOULD USE THE MULTI ONLY IF IT FITS THE REST OF YOUR SYSTEM AND IS USED TO FIX A BUG ELSEWHERE. OTHER THAN THAT, STANDARD WEAK 2s ARE PROBABLY SUPERIOR!
