As I have mentioned, I am now taking care a bit of the BBO Advanced FD file. Obviously, I would appreciate any possible help for that. Which could be:

1. Pointing out mistakes
2. Pointing out gaps in the file (of course there are many, but that will help me prioritize)
3. Comments/criticism on the choices made
4. Send me changes (by e-mail to arend.bayer-at-web-dot-de)!

About 4.: If you see any error, you can just correct it and send me the corrected file. I am keeping the file under revision control; this means that I can easily integrate your changes, even if I have in mean time made further changes myself. Also, it means I can easily check what exactly you have changed.
In other words: don't worry about all that, just make changes and send them my way.

By the way, it is also very easy to integrate parts of other files. So, if anyone has a personal FD file of which parts could be useful for BBO advanced, you can just send it, and I can extract what is useful.

Maybe I should mention a little what I have done so far. After some house-keeping (e.g. I have fixed some 150 bids that had "No agreement" as disposition) I have somewhat completed the NT system. I added Lebensohl over weak two (not mentioned in Fred's writeup, but that seems universally accepted), and made Lebensohl after 1NT a little more consistent (direct stayman or 3N now always deny a stopper).

I was positively surprised that BWS plays negative doubles after interference over 1N, and added that too. In fact, I think I will often follow BWS unless I think the BWS choice would be a clear surprise for most.

I think currently the biggest gap in the file (and probably all standard FD files, I haven't checked) are advances in competition. One really needs to know which are forcing, and up to which level.

I think I will use BWS after 1M-(X):
1-level forcing, 2-level non-forcing, jumps preemptive, double jumps splinter.

I like fit-showing jumps, but I just don't think they are standard enough. (Unless by passed hand.) Also, I don't think people exactly agree which of them are forcing.

By the way, someone should fork off a BBF advanced file, that uses transfers and fit jumps here!

There is now a new version on the server "BBO Advanced 1.2". It has some fixes regarding the structure after 1m (unfortunately not complete yet, will be in the next version), more completion of the 1N structure, Bergen raises made in sync with Fred's writeup, some simplification after 3-level preempts, Lebensohl after w2 included...

For the next version:
I have switched to simple Drury, since that seems more common and is also the choice in Fred's writeup. Think I should deal with NMF next. Also some fixes that were apparently copy-paste errors.

If anybody has a file with a 1way or 2way NMF structure it would be great if I could steal bits (I can extract it myself).

arend, i don't have a separate file but if you want i'll post the 2/1 file somewhere and you can pull it out... some editing required tho, it's based on a 12-15 nt so the 1nt rebids won't be 16-17 as i show them

Some random things I just noticed in BBO Advanced 1.2:

Why does 1♥-1♠-4♣ (forcing) have a different disposition than 1♥-1♠-4♦ (slam try?)

I think 1♥-1NT-2♠-2NT should be disposition "puppet" rather than "transfer", and it's response needs to be marked artificial.

I think the number of spades shown by 1♥-1NT-2♠-2NT-3♣-3♠ and 1♥-1NT-2♠-3♠ are wrong. If not, then in the former case, I'm surprised we could stop below game with 10+ Spades and 23+ Points between us.

You mentioned revision control, is there any chance this could be made available for others? I'd be happy to set up a publicly-accessible subversion server if you don't have the resources, or indeed for any other standard systems as well.
