Can anyone detail these, or give a link?

Also, if you have played them, how do they compare to Stayman/transfers, and would they work well with a weak or mini notrump?

I've heard really good things about Keri and am strongly considering shifting to use this over MOSCITO's weak NT. With this said and done, I don't have a good write up handy. I've heard that the best reference is

Bid Better, Much Better, After Opening 1NT by Klinger.

I really like the Keri structure. I am not going to type up the whole thing (it covers 6 pages in Klingers book)..

But here's the basic framework...

2c / 2d / 2h/ 2nt are all transfers to diamonds/hearts/spades/clubs respectively and can be passed

After 1nt-2c-2d then
2h = 4h GI
2s = 4s GI
2nt = artificial GF asking about openers major holdings
3c = 6+ cl GI
3d = 6+d GI
3h = 4h/5d GF
3s = 4s/5d GF
3nt = 5d-3-3-2 slam invite
4c = 6d/4c slam invite+
4d = 6+d club void in clubs slam invite+
4h/4s = 6+d void in bid major, slam invite+
4nt = rkc diamonds

After 1nt-2d-2h then
2s = s/h 4-4, 5-4, 5-5 GI
2nt = 5h and a 4 card minor GF+
3c = 5h/5c GF+
3d = 5h/5d GF+
3h = 6+h GI
3s = 5h, 4s GF
3nt = choice of games (pass or 4h)
4c/4d = 6h, void in bid suit slam invite
4h = 6h void in spades, slam invite
4s = 5s, 5h slam invite
4nt = 6h-3-3-2 slam invite

After 1nt-2h-2s then
2nt = 5s/4minor GF
3c/3d = 5spades/5m GF+
3h = 5s/4h GF
3s = 6s GI
3nt = choice of games
4c/4d = 5s, void in bid suit, slam invite
4h = 5,5 majors pass or correct
4s = 6s, void in h, slam invite

After 1nt-2nt-3c then
3d - 4/4 minors GF
3h = 5c/4h GF
3s = 5c/4s GF
3nt = 5-3-3-2 slam invite
4c = 6c, 4d slam invite
4d/4h/4s = 6cl, void in bid suit, slam invite
4nt = rkc clubs

1nt-2s is a range enquiry...
1nt-3suit are GF 3 suiters (bid the suit below the shortage, 3s = club short)

There's a lot more detail to the structure than this..and Im doing it from memory (a detail might be slightly wrong) - I've lent the book to a friend - unless thehog or someone who has the book posts Ill post more detail when I get the book back.

I have just read this post. I have a detailed write up prepared by an ex pd with whom I played it. I can send it to anyone who wishes a copy.
Fwiw I personally believe that this is the best structure over a NT - weak or strong - bar none! I believe the only reason it has not become more popular to this date is that it does require a bit of work.
It can also be used as a type of 2 way checkback over a 1NT rebid by opener.
