Seems like that may hold you to 11 tricks, though, if both follow to 3 rounds of clubs, and you then misguess who has 4 diamonds…

Doesn't really say in that quote that BBO will keep the old version available until end of 2020… but maybe they will…

Thankfully, it still works, though.

And this reminds me of the old OKB GUI, like 25 years ago,
was completely Awesome compared to any UI today :)

What a weird world of “development”…

In the settings,
turn off animations,
turn off sound.

They are just annoying.

@Hopkins

That I don't know.
Usually ends with a burning trainwreck after you try sthg “creative” with the robots, though.

The 2NT-reply should just been abolished, and answer 2 instead.

Most annoying is robot's horrible habit of replying
2-2NT=8+hcp, bal.
After that, all bids from opener are natural 5+suit.
So with 2 balanced hands, it gets impossible to find a 44 fit.
Awful.

Thanks Steve.

I haven't given much thought, yet, to those more unusual distributions.
But my initial idea is that you first go by suit-quality…

Thus, with 6-5:
if the 5-card suit has poorer quality, you initially bid it as 6-4, while
if the 6-card suit has poorer quality, you initially bid it as 5-5.

Then “improvise” from there just like in a natural system.
Esp if the strong hand signs off in the suit where you have an extra card, you should consider an extra slam-try, of course.

There is, however, space available to develop the relay-sequences further for those really digging into it, but I wanted here to keep it reasonably simple as a general introduction.

Here's one layout where that line fails:

You can lead anything, but a club, at trick 3.

On a single deal — well, anything is possible, of course, but the issue of 4th hand causing us much trouble *after* 1-1, both in theory and practical experience, is really tiny.

Picture yourself sitting with a known 8+hcp before you and a known 16+hcp behind you and they established GF — if you make a move other than a *really sound* overcall, you are a sitting duck for penalty-doubles.
So successful overcalls are certainly rare in that position.

Another issue is, that even if you were dealt a decent enough hand in this position, it means your pard is likely near broke, so even when you are lucky to evade being doubled, you are sending a signal to your oppos that this might be the exception when the stronger hand should *not* declare.

In all situations, where only one opponent has bid to show strength and his pard only passed, it is generally favourable to have the *bidder* lead to trick one, and your action may well help opponents achieve this advantage.

Sorry, I don't really get your argument…

I was mentioning the case when responder starts 1NT,
and then it turns out you have no 8-card major-fit,
after which you most often end up in NT-contract.

That would seem like a very frequent case…

As I write in the article linked, you can never *guarantee* right-siding the contract on *every single* deal.
The aim is to find a scheme that maximizes the statistical probability.

Well… no, that doesn't seem to cut it.

If responder bids 1NT with 5+clubs, I would estimate in a majority of cases, the result will be a wrong-sided NT-contract.

Additionally, unless it turns out we might be in the slam-zone, most often we don't want to start spilling any information *at all* abt minor-lengths – it only helps defenders.
This is another strong feature of our scheme.

Also, what does responder bid with *both* majors – 4-4, 4-5, 5-4, …?

In the end, I think you will have to invest quite some effort to come up with a more efficient scheme, than the one I presented.

And if you do, I'd definitely be interested! :)

It should be technically possible to write OCR-based software to facilitate the conversion from books to LIN-files.
Since different books may use slightly different layouts/conventions/formats to present deals and bidding, there would probably need to be some customizable part for each book-style.

So the work could then be divided along the lines:

1) Scan all deals with auctions from a book.

2) For each image/deal, validate that it can be parsed to a consistent information (here's where the customization-part will be worked out).

3) Convert the information parsed to LIN-files.

It could, but the 1NT response (3-3+ majors) seems VERY prone to wrong-side the contract, which is what this scheme is designed to avoid.

@Richard – Only because spades are 4-2, it doesn't mean 3 must go down. We might be able to use s as the “second trump-suit”.

3 cannot be forcing, after 2 limited.

Pard is suggesting 4-3 contract with Axx (perhaps AJx) and probably ruffing value in clubs and some extras.

Hope I can make 3 and expect it to score pretty well in MP.
