I was told 4clubs is gerber after NT so based on the following, can someone explain to me why Gerber is so bad
As I really cant see how you can confuse this bid as anything else but Gerber
1NT - 4 C = Ace ask
2NT - 4C = Ace ask
1NT - 4NT = Quantative
2NT - 4NT = Quantative
surely it must have some use???????

Its good when we dont have a trump suit.
The are alternatives for the 4c, like
1NT-4c some play as showing hearts, so they have can play 4H/4S naturally and decide who they prefer to be the declarer of the hand.
there are some less ovious sequences ,
for example
1NT-2c
2H - 4c
here also 4nt is quentative but some might play 4c as splitner and i myself used to play this 4c as showing 4 card club suit (3c would show 5 cards) to find slams (not that i recomment it)
same after transfers
1NT-2h
2s 4c
could be played as a self splinter.

The standard Gerber can be improved a LOT! Normally, 5♣ will ask for Kings. If you use a step-1 response after the initial Gerber answer (4♥ after 4♦ answer, 4♠ after 4♥ answer, 5♣ after 4♠ or 4NT response - 4NT would be to play), then you save yourself some extra space in most situations. You can even use Roman responses so you'll know what Aces partner has exactly when he has 2. You can even start showing specific Kings, and there are many other possibilities to fine-tune this convention.

1C-1H
2C-2NT
3C-3NT
4C <<---- meant this as gerber....
Others hearing this bid will take the 4C as Gerber when opener meant it as not gerber....
This stuff is silly, and is why so many people don't like Gerber. Play it right and it is a necessary, and useful convention.

Most textbooks suggest Gerber is on only as a Jumpbid, so the given sequence would not be misunderstood.

2D 2H weak scramble for either major
2S NF 5 S 4H invitational
2NT game invitation may or may not contain 4 card major
3C/D natural game force, generally slam-ish
3H/S smolen, showing 5 of the un-bid major and 4 of the bid major, GF
3NT to play
4C Roman gerber (0314 or 1430) then 2 minimum and 2 maximum
4D 5-5+ majors game forcing and non-slamish
4H key card for clubs
4S key card for diamonds
This is the agreement I have with my reg p, we agreed this 4 months ago, does thisRoman gerber constitute a good use of the 4!C bid (in your opinion)

1NT-2C-2D-...
2H = scramble. I don't like this but that's a personal thing, lol.
4C = roman gerber. It's ok to use it if you like it. I don't
4H/S = I would keep this as natural. Too easy to forget it's RKCB and you can already show a minor with the 3m bid.

4S key card for diamonds
I remember that post with 6 hearts and 4 spades, where some of us like Ben Ron and myself thought the right bid after 2c-2d is 4H.
Why do you need a key card for minor now ? partner can have a doublton in this minor, so why not just bid 3m ?

Just make a few general rules. Gerber is ALWAYS a jump (5♣) if necessary), always over a bid of NT, and doesn't apply when we have raised a suit earlier in the auction.

In keri 4C is transfer to 4H. You can follow up with 4NT if you want to ask for keys. This is our "gerber" lol
Are you saying
1NT-2C
2H-4C <<---- is transfer to hearts?
If not, what is your point.. The rest of the world does this with Texas transfer...
1NT-4D
4H-4NT <-- RKCB for hearts
And we keep the following auction as quant.
1NT-2D
2H-4NT <-- quantitative with a heart suit

Ben - in Keri, the auction: 1N - 2♣ - 2♥ doesn't exist; 2♣ always relays to 2♦. Keri also uses South African Texas, so 4♦ = spades. Your 3rd auction is still quantitative.

No, I meant
1NT 4C = transfer to hearts, follow up with 4NT RKCB if you want.
1NT 2D
2H 4/5NT = quantitative with a 5332, respectively non-forcing and forcing.
In keri 1NT-2C forces 2D, so
1NT 2C
2H 4C
should not exist. It can of course happen if opener decides to evade the 2D mandatory response. That would be non-systemic, and therefore natural. It would probably show 5 good hearts, 3 diams (in case opener wanted to pass the 2D response) and a max. Then 4C should be a splinter because responder could setup a force by bidding 3H, a bid that doesn't make much sense as invitational at this stage.
