No, North is just showing both minors if he really is an expert. An expert with gerber in their profile does raise a red flag though.

In the forums there is automated script to return "no" in response to the prompt "gerber?".

2♣ - 2♦; 3♦ - 3NT; 4♣ is not Gerber but 2♣ - 2♦; 2NT - 4♣ will be for many pairs.

A common agreement is that 4♣ has to be a jump after a natural NT bid, but even that has exceptions. But it means that if you want to bid Gerber when the last NT bid was 3NT, you have to jump to 5♣. Obviously, this can usually only be used if you're trying to decide between a small and grand slam -- it might come up in an auction like 2♣ - 2♦ - 3NT - 5♣.

Could still stop in 5N, perhaps even 5 of suit, but that would be stopping on a dime. So, I think if your using 5♣ as super-Gerber then you have a big hand.

It is only Gerber for those who don't know any better.

Isn't Gerber standard for unknown self-rated experts on BBO?

Gerber 4Clubs only operates opposite a 1 or 2NT opener.
Its considered as a museum piece in the modern game.
I've never seen it being used in any top flight tournaments of today.

No, it definitely is NOT Gerber unless there is a specific - and misguided - agreement that it is.

Undiscussed, 4C shows clubs. Period.

North is looking for slam in one of his/her minor suits.

On BBO, I have never had any trouble with Gerber. During an auction somehow related to no trump, one player will bid 4!c. After a pause, either the bidder or his partner will ask, "Gerber.?" If the bidder answers yes, then it is Gerber. If he says no, then it is not.

This works for suit auctions too, as well as for non-Gerber situations such as two-way 2s (strong or weak) and multi-range NT openings (allows you to cover all balanced hands between 10 and 24hcp with just 2 openings). I cannot imagine why this is not used more widely in face-to-face bridge. :blink: B-)

That's because players employ the multi defence to 1NT whereby a 2C overcall shows the majors, except of course if you happen to hold clubs in which case you can announce it to be natural. I'm sure there are other options available also, such as clubs and a major.
