After 2nt,what's the meaning s of 3♣ by responder?

3♣ says " New sut forcing --- 5+♠,7+TPs ".

Is it a checkback bid?

Is it a 4-card new ♣ suit?

I think here need clear definitions on 3♣.

New Minor Forcing is a convention. You can think of it as checkback.

It could be clearer, yes. But, the description mentions ♠ length and point count only, not ♣ length, so it should be taken as artificial.

There is no need for anything clearer... if you want "new minor forcing" explained better, you might as well say that you want Stayman explained better.

3♣ says " New sut forcing[/size]

 

It actually says New minor forcing.

Mostly agree, I don't know what the character limit is for GIB explanations but it is a lot shorter than the twitter limit. :) While you're not supposed to give the name of a convention when describing a bid in a live game, with GIB it seems like a very good idea instead of the usual non descriptive description we are all accustomed to. Since you are already on a computing device, you can Google the meaning.

Ok, now I presume all of you are correct,what's the following after 3♣ as new minor forcing? Gib's answer is 4♣,is it correct ?

Strangely, perhaps, I think that it may be (correct). He hasn't got a third Spade to bid 3S, he hasn't got a 4th Heart to bid 3H, he hasn't got a Diamond guard, and there is not a lot left.

 

The interesting question that I have not addressed is the distinction between 3D and 3N. If they were used to distinguish quality of Diamonds, then it might leave 3N open as an option to partner. But perhaps both would show something in Diamonds sufficient for at least a single stopper.

I think the description provided for 4♣ should deny 3 spades and it should deny 4 hearts. 2N probably should have denied 5 clubs and, of course, it's not a "jump in NT".
