2 level Bids can have their own feed, as the Multi2♦ effects all the bids above.

I will leave 2NT openings to partnership ideas and there are matters to be discussed about the 2♦-2Major-2NT 19-21 balanced hands.

All 4441 16+ hands any singleton must be opened 2♦, if you open 1♣ you will find yourself without an effective rebid, and will lose control. Rather hand over control with the opening bid.

You see, to our advantage our opponents should not be allowed to know if we are strong or weak at the opening bid, since even we don't know, until after the relay. They should be wary of out strong hand traps for poor interference.

The Multi 2♦. Bermy Style


Control Precision opening Bids 2♦

The Multi Two Diamond is our free 2♦ opening bid that deals with our long 6 card majors. This bid also allows us to bid those hands that are unbiddable in Control Precision, such as all 16+ 4441 hands and 22-24 Balanced Hands. It also frees up both 2♥and 2♠ for 2 suit weak hands. 2NT, also free becomes 11-13 High Card Points with both minors at least 5x.

Control Bid

2 ♥
Weak relay bid, up to say 12 Hcp . Will be passed when opener has 6x♥ weak

2♠
Strong relay bid. Forcing

2NT

With 16+ 4441 hands we open 2♦ and then all the 3 and 4 level bids are available to us to describe exactly where the singleton lies. Blind Bidder bids Bid One Below Singleton for tempo and stability in case Control Bidder is exceptionally weak. This allows Control Bidder to pass.
Control bidder will see partner’s hand, and know the exact point range and shape of the hand. Armed with the exact location of the singleton, he will place the final contract perfectly.

[Bermy]

With added explanation

When Bidding with 4441 hand 3 things usuall happen.

1) No decent Major fit,
2) A horrible misfit
3) A great fit with cross ruff potential or 2 suit fit.

By bidding 1 below the singleton, Control Bidder always has that option to pass if he needs to do so.

[Bermy]

Bidding the Multi with a Two Spade Response.

When the Control Bid is 2 ♠ forcing, it is much like our 2♥, only now we have become cramped for space, so beware bids can get confusing here. Blind Bidder is forced to bid, so pass is not an option and still has to be able to bid its long weak majors
Therefore 3 level bids have to be saved for the weak pre-empt hands with BOBs rule still applying for higher bids. The positive response gives you more room at the higher levels however.

Phew note the complications.

[Bermy]

As for opening 2NT, it is rather an open bid really, for further development.

We used it for Minors, but got slaughtered by major bidding opps, especially when they become declarer and know our exact distribution.

Now we only use it for minors as a Blind cry for help, asking partner to please make a sac if necessary.

[Zelandakh]

You seem to have a huge hole in your system for responding hands that want to play is 2♠ opposite spades but have game interest opposite hearts. You responses also rob Responder of our side's mostpotent weapon after a Multi 2♦ opening - ramping up the bidding to 3M or so quickly on a weak hand with both majors.

Not to be negative though, I have a constructive suggestion that would at least help a little with the first case:

3♣…. Free for now Good Options are available

This should be used for splitting up the range of the weak heart hand type. Either 3♣ should be a max and 3♥ a min or (my choice) vice versa. It would be logical to use the 3♦ rebid for a similar purpose in spades and that would be my suggestion, so that 2♠ can also handle hands worth an invite in either major. But perhaps you have a better option in mind.

You will find that competent opponents are happy to get involved in your Multi auctions despite the strong options. You need some basic rules here if not full agreements. This is even more important for you than other Multi pairs, since you have chosen to play non-standard follow-ups.

[Vampyr]

You might save a lot of space if you used just one rebid to indicate a strong 4441 hand rather than using an entire bid for every singletonand every range.

Since it seems like your goal is to have a "modern standard" precision system that a wide range of people can play, you should be aware that 2♦ Multi is essentially banned in North American bridge competition (outside of a few elite events with long rounds). This seems like something of a handicap to creating a standard, especially since BBO and these fora have something of a US-heavy skew. Obviously in the rest of the world this isn't really a consideration though.

"Legal in America" is too high a bar to set for system designers, I think. Whatever your opinion of the merits or otherwise of the OP's ideas, conforming to the most restrictive regulations in the world will stifle innovation.

awm's post was useful and nuanced. If you're criticizing it, I think you misread it.

I will make no comment on that, since that ruling is totally beyond my comprehension, and does not comply with the spirit of the game, in my opinion. It has been around for many years now, and is restricting development. Perhaps it is time for a rethink on that.
