Looks good except for a couple of typos. One hand type that might be problematic is 4-4 majors with slam interest but that is easy to solve. I suppose the plan is o use CONFIT with that but it seems to be a fair way behind Stayman-based methods. A more serious omission is not having a way of showing a long suit at the 3 level and starting a cue auction. I know this is popular these days but I think it is a mistake. It is also another easy fix within this structure. You are also missing an invite with a long, broken minor. Since this is also the hand type I cut from my structure, you can probably guess that I do not find this a serious issue.

Yes I guess the structure is very focused on showing shape, rather than establishing a fit and then cue bid. Perhaps that's a problem, I'm not sure. There are many invitational hands which aren't included. The ones that are included:
- Balanced INV
- INV with a four card major
- INV with 4-4 majors
- INV with 5 card major
- INV with 6 card major
- INV with 5-5 majors
One type that I would like to include is INV with 5-4 majors, but right now you have to treat these as 4-4 or just show the five card suit. Perhaps there is too much attention to GF auctions. When aiming at the right part score there is a gain in being able to play 2D. We do not, however, have a bid available for weak with both majors (not a big loss in my opinion), nor weak with both minors.

Very nice presentation, are you planning to make your compiler available? Can we get a glimpse of the source format?
Thanks! I have been thinking about making it available, but I think it would be awkward for someone who isn't familiar with the Emacs text editor and
org-mode. Here's a snippet of source:
* Lakebeach NT
The Lakebeach NT structure is inspired by [[http://www.jackbridge.com/pdf/eheeman.pdf][Heeman]], Notrump bidding the Scanian Way, and Meckwell's NT structure. The structure has very few asking bids, preferring to show responder's shape instead. The keystones are 2NT as Puppet Stayman, 2!d!h as transfers (with second round transfer follow-ups) and 2!c as a puppet to 2!d.
| 1NT | ? |
- 2!c :: Puppet to 2!d.
The puppet to 2!d is the strangest bid in the Lakebeach NT structure. Responder may have:
- A hand wanting to sign off in 2!h or 2!s.
- A GF unbalanced hand with 4M.
- 4-4 majors with at least INV values.
- A four card major and INV values.
The main purpose of the bid is to invite of force game with exactly four cards in one, or both, of the majors. A somewhat balanced hand game forcing hand with a four card major /does not/ respond 2!c though, but instead responds 2NT.
- 2!d :: Forced.
- Pass :: Weak with diamonds.
- 2!h :: Weak with !s or INV+ with 4!s.
- 2!s :: Normal bid.
The continuation after this bid is symmetric with 1NT--2!c; 2!d--2NT+, but with 4!s instead of 4!h.
- Higher :: Super-accept with good max and 4!s.
- 2!s :: INV+ 4-4 majors.
- 2NT :: Minimum, no major.
- Pass :: INV 4-4 majors.
- 3!c!d :: Singleton, 4441, GF.
- 3!h :: 4-4-5-0, GF.
- 3!s :: 4-4-0-5, GF.
- 3NT :: To play.
- 3!c :: Max or 4M.
- 3!d :: 4-4 INV.
- 3!h :: Short clubs, GF.
- 3!s :: Short diamonds, GF.
- 3NT :: 4-4 COG.
- 2NT :: INV 4!h.
- 3!c :: GF 5+!c and 4!h.
- 3!d :: Relay.
The continuation after the relay is symmetric with 1NT--2!c; 2!d--3!h+.
- 3!d :: GF three-suiter, short spades.
- 3!h :: Relay
- 3!s :: 1-4-4-4.
- 3NT :: COG.
- 4!c!d :: Natural 5440.
- 3NT :: Suggestion to play.
- 3!h :: GF 5+!d, 4!h and short clubs.
- 3!s :: GF 5+!d, 4!h and short spades.
- 3NT :: NF SI 5+!d, 4!h.
- Higher :: SI 5+!d, 4!h.
- 2!d :: Transfer. 5+!h.
- 2!h :: Normal bid.
- Pass :: Weak with hearts.
- 2!s :: INV with 5!h or INV+ 5-5 majors.
- 2NT :: Minimum, not 3!h.
- Pass :: INV 5!h.
- 3!c!d :: Short minor, 5-5 majors. SI.
- 3!h :: 5-5 majors, INV.
- 4!c!d :: Void and 5-5 majors.
- 4!h :: 5-5 majors, COG.
- 3!c :: 3!h or max.
- 3!d :: 5!h, INV.
- 3!h :: 5-5 majors, INV.
- 3!s :: 5-5 majors, short clubs. SI.
- 3NT :: 5-5 majors, short diamonds. SI.
- 4!c!d :: Void and 5-5 majors.
- 4!h :: 5-5 majors, COG.
- 2NT :: Transfer. 4+!c, GF.
- 3!c :: Relay.
- 3!d :: Short diamonds.
- 3!h :: Short spades.
- 3!s :: 0-5-4-4.
- 3NT :: NF SI.
