How is 16 balanced handled?

Is 2NT-3♣ a non-forcing ask?

[Rossoneri]

Don't like the way the system handles balanced hands. Range seems too wide for comfort.

[DrTodd13]

What would your argument be that this is better than other systems out there? Seems precision-ish except putting 2♣ hands back in 1♣ and taking the really strong hands and putting them back in 2♣. There is something to be said for consistency and until I hear your reasoning it is hard to understand why some things are in 1♣ and others in 2♣ or 2N. There's enough room after 1♣ to sort out all the strong hands be they balanced or unbalanced.

I think that the M-Tribe system is not only easier to learn ,but also easier to deepen than the most seen others,
just like a tribe with its mystery and simplicity,and
just like the bridge game ,and the bridge players ;

Mystery? Easier to deepen? Care to elaborate?

[Apollo81]

The worst things about this system, in order, are:

1. The 2♣ opening is forcing, and describes a set of hands where responder will commonly want to play in 2♣.

2. The 1♣ opening can be a single suited club 12-16 or any 17-20. This means that an unbalanced 17-20 with primary clubs and another suit will be virtually impossible to show.

3. The forcing 2NT opener will be a disaster pretty much whenever opener has a strong 2NT and the field is passing a strong 2NT.

1,The similar 2C opening also can be seen in Precision system or Polish WJ system ;

2,"an unbalanced 17-20 with primary clubs and another suit " is impossible directly show,but is simply to show indirectly;

3,something contradicted itself?

1. WJ/Precision 2C doesn't have the set of strong hands, therefore responder can safely pass.

2. So now after your club rebid what does responder know, you are 12-20 with clubs? Try showing 17-20 with clubs after a jump overcall by one of the opponents.

3. The forcing 2NT opener will be a disaster pretty much whenever opener has a strong 2NT and the field is passing a strong 2NT.
