\section{Introduction}

\subsection{BML - Bridge Bidding Markup Language}

The notation in this document is in BML format, see
github.com/gpaulissen/bml/blob/master/README.org.
\bigbreak
This notation allows for text documents with simple bidding tables.
\bigbreak
\subsubsection{Output}

Using a simple BML document one can generate:
\bigbreak
\begin{itemize}
\item a PDF file

\item an HTML file

\item a BSS file, a BBO system file, which can be uploaded using the BBO desktop Windows client.

\end{itemize}
\bigbreak
\subsection{Abbreviations}

The abbreviations used are mostly from the WBF with some changes, see also the
Abbreviations chapter at the end.

\section{Opening bids}

Let's start with the basic opening structure of the system (:
\bigbreak
\
\dirtree{%%
 .1 \O. 
 .2 1\BC......\begin{minipage}[t]{0.8\textwidth}
2+\BC , NAT or BAL, 11+ HCP (12+ if BAL)
\end{minipage}. 
 .2 1\BD......\begin{minipage}[t]{0.8\textwidth}
4+\BD , 11+ HCP (12+ if BAL)
\end{minipage}.

\end{minipage}. 
 .2 1NT.....\begin{minipage}[t]{0.8\textwidth}

\end{minipage}. 
 .2 2NT.....\begin{minipage}[t]{0.8\textwidth}

\end{minipage}. 
 .2 3NT.....\begin{minipage}[t]{0.8\textwidth}

\bigbreak
\section{The 1 major opening}

One of a major promises 5 cards and at least 11 HCP. It is limited since with
game forcing hands you open at the two level.

\bigbreak
\subsection{Remarks by GJP}

Too much space is used by all fit bids. Two over one and invitational hands
like Ax, xxx, xx, KQJ10xx will be too difficult to bid.
\bigbreak
\subsection{Passed hand bidding}

We play 2\BC\ Drury after an opening in third or fourt hand. Opener returns to
his major when weak (or bids 2\BH\ after 1\BS ). 2\BD\ is waiting and positive. Bids
above 2M by opener are forcing game.
\bigbreak
A single jump in a new suit after 1M is not a fit bid (so no ``annonce de rencontre''). We
never play single jumps as fit bids.
\bigbreak
\subsection{2NT after intervention}

Always natural, not fit like without intervention.
\bigbreak
\section{The 1NT Opening}

Shows 15-17 HCP (semi)Balanced, 5m422 or 6m are possible and rarely a singleton
K or Q. 14 or 17 with a 5crd suit are upgraded regularly.

After a double we play system on. The only new bid is redouble which depends
on the meaning of double. If double is for penalties (or just showing values),
the redouble is a Puppet to 2\BC . In any other case the redouble shows values
as well and is forcing till 2\BS .

When they bid over our transfer a double is just for penalties.  Support shows
a good hand with fit, after 2D at least 4 cards (partner may have 4\BH 5\BS\ in
the majors). If they bid our cuebid dbl shows fit and willingness to compete.
\bigbreak
\section{Weak-two opening bids}

Both 2\BH\ and 2\BS\ show a weak two bid and less than a one level opening
bid. Non-vulnerable possibly 5M (especially by Albert) and usually 5-10
HCP. Vulnerable the opening promises a good 6 card suit and 9-11 HCP.
\bigbreak
\subsection{Answers}

A change of suits is non forcing after a non-vulnerable opening but forcing otherwise.

\subsubsection{2M-2NT}

Classic French, so a bid shows a top honor and a repetition is the weakest bid.

\subsection{Intervention}

\section{Bidding with intervention}

This chapter is about bidding with intervention in general, when we open or
they open.
\bigbreak
\subsection{Doubles}

As a rule of thumb you can say, the more your partner knows about your hand,
the more for penalties it is. Quite logical, but still.
\bigbreak
\subsubsection{Below game in competitive bidding}

Doubles are for take-out. I consider preempts also competive bidding.
\bigbreak
Examples: 1\BH -(3\BS )-D is a take-out double.
\bigbreak
\subsubsection{Game or higher}

A double is a proposition to defend.
\bigbreak
\subsubsection{Five level}

Double is for penalties and may be a Lightner double.
\bigbreak
\subsection{New suit after partners opening and an intervention}

As a general rule your new suit is forcing but not forcing for one round, so
you may pass after partners rebid.
\bigbreak
\subsection{Take care when partner is non vulnerable and preempted}

Refrain from bidding when partner may already have applied maximum
pressure non-vulnerable. You may only bid if you think you may make it.
\bigbreak
\subsection{Reverses into a suit not promised by partner are strong as usual}

For example after 1\BC -(1\BS )-D-(2\BS ) you can bid 3\BH\ with a normal opening
(although not too bad). But 3\BD\ is a reverse since partner did not promise 4
cards in diamonds.
\bigbreak
\section{They open the bidding}

This chapter is about our defensive bidding if the opponent opens something on the 1 level.
\bigbreak
\subsection{1X}

\subsubsection{Simple overcalls}

No taboos, preferably a good suit and maybe 4 cards on the 1 level.
\bigbreak
\paragraph{Fit responses}

A simple fit bid shows about 8-11 HCP, stronger than usual thus.
\bigbreak
A jump in their suit suit shows 4 cards fit and an opening.
\bigbreak
A jump fit bid in a major shows 4 trumps, a singleton and about 10-11 HCP.
\bigbreak
\paragraph{Non-fit responses}

A change of suit is non forcing at the one level. 1NT and 2NT are natural,
something like 8-11 or 12-15 HCP respectively.
\bigbreak
\subsubsection{1NT intervention}

This shows the same kind of hand as a 1NT opening albeit a little bit stronger
and usually with a stopper in their suit.
\bigbreak
The responses hereafter are just like after a 1NT opening we ignore their
bid(s).
\bigbreak
\subsection{1NT Opening}

The meaning of the bids remains unchanged when you are in second or fourth position.
\bigbreak
The meaning of our dbl depends on the strength of their 1NT opening. If the
lower limit is at most 13 HCP we consider it a weak NT. So a 14-16 NT is a
strong NT. After a strong 1NT (or if the doubler did not open) we play double
as 5+m-4M else it is for penalties.

\subsection{2\pdfd\ Multi-coloured}

Double is Italien (?).
\bigbreak
I personnaly prefer a Polish double (maybe the same). A double on 2\BD\ shows a
take-out on spades (short spades). A pass followed by double is a take-out on
hearts (shows shortness in hearts).

\subsubsection{They bid after our two-suited overcall}

If they bid a new suit intended as natural, dbl is penalty.  If they support
each other, dbl is for take-out and may be INV for the major if you don't have
another invitational bid.  If they bid one of our suits, dbl means that you would have
liked to bid that.

\subsection{fit after 1M and intervention below 2NT}

The bid of 2NT shows at least four cards fit and at least an invitational hand, for
example 1\BH -(2\BH )-2NT. There is one exception: when the cue bid is above 3M,
2NT just shows at least three cards fit like 1\BH -(2\BS )-2NT.

\section{Transfer Lebensohl}

We play this after our 1 NT opening and their intervention of 2\BC\ till
2\BS . And also after their weak two level opening bids, whether it be some kind
or multi or not.
\bigbreak
\subsection{One suit known}

Transfer Lebensohl starts at 2NT. There are 4 types of special bids:
\bigbreak
\begin{enumerate}
\item A transfer to their suit which is FG and shows at 4 cards in at least one
   of the unbid majors.

\item 2NT, a Puppet to 3\BC . It can be either a sign-off below their suit or FG
   with at least 5 clubs.

\item A transfer to a suit. This is at least invitational and
   shows 5 cards in the transfer suit unless it is a transfer in a major which
   has been implied by partner's take-out double. It does not matter whether the transfer
   is above or below their suit.

\item 3\BS . This is FG and denies a stop and it denies a 4 card major in an unbid
   suit.

\section{Defense against two-suiters}

The cheapest bid in of their suits shows the fourth suit and is forcing to
game. Thus not the lowest in the sense of clubs, diamonds but the most
economical bid. The most expensive bid in one of their suits shows fit and is
at least invitational. The reason for this scheme is that you need more space
if you do not have a fit. A 2NT bid shows fit with at least 4 cards and is at
least invitational.
\bigbreak
\section{Slem bidding}

\subsection{Game forcing fit situations}

\subsubsection{Major at the three level}

For example 1\BS -2\BH -3\BH .
\bigbreak
When a fit has been agreed upon, one may sign-off in four of the major as a
sign-off. 3NT is not a minimum but not very strong neither ("la première
zone") and a control bid is stronger ("la seconde zone").
\bigbreak

 .2 5\BS......\begin{minipage}[t]{0.8\textwidth}

\bigbreak
\subsubsection{Asking for the trump Queen}

The trump Queen can be demanded after 5\BC /5\BD\ with the first free bid. 
The lowest of 5NT and the trump suit without jump denies the Queen. Any other
bid in a suit promises the Queen plus only the King in that suit OR the two
other Kings (the King of trumps is ignored of course).
\bigbreak
\subsubsection{Intervention after 4NT}

Double (or redouble) is for penalties. Pass shows an even number : 0/2/4 key
cards. The first free bid shows 1/3/5 key cards.
