\HEADING{Takeout Doubles}
A direct double of 1\x{} is for takeout, and shows 12+~pts.\ with
support for all other suits, or 18+~pts.\ and any shape.  
(With 4 in 
each @h@s, it is permissible to double without support for the unbid 
minor.  With a singleton or void in \x{} one may shade to 10+~pts.
With 4-3-3-3 distribution one should avoid takeout doubles.)

The second negative is used by responder to respect the force.  The
cheaper minor rebid, or 3@n after 3@d, means 0--4 pts.\ and denies any
aces.  After this, bidding is natural; unless opener immediately
rebids his suit, this sequence is \fgame\par

@-\ your last bid was 3@n and you had not agreed on @h@s as trump;\par

@-\ partner has never bid or doubled, but you have;\par
\hangafter=1 \hangindent=1em
@-\ it's immediately after Stayman or a Jacoby Transfer bid.\par

\quad 5@c\ 0 (or 4) aces.\hfill5@h\ 2 aces.\quad\break
\null\quad 5@d\ 1 ace.\hfill5@s\ 3 aces.\quad\break
After interference, use DOPI:\par
\setbox\tmp=\hbox{\sc Pass}
\quad\hbox to \wd\tmp{\sc Dbl\hfil}\ 0 aces.\hfill 
Cheapest bid 2 aces.\quad\break
\noindent\null\quad\box\tmp\ 1 ace.\hfill
Next bid 3 aces.\quad\break
A void does not count as an ace.\par
\heading{Key-card Blackwood}
In this variant, the trump king counts as an ace, and 5@d shows 1 or 5
``key cards''.\par
\heading{Gerber}
A jump bid of 4@c when partner's last bid was a natural 1@n or 2@n is
Gerber.  Responses start at 4@d (0 or 4 aces).\par
\heading{Cue bids}
A cue bid displays interest in slam and indicates first-round control
(ace or void).  A minimum bid in a new suit for your side is a cue bid
if it is above 3 of your trump suit.  (However, if your trump
suit is @c@d and the new bid is 3@h@s, and another suit remains unbid,
then the bid of 3@h@s may be seeking a major-suit fit.)\par
\quad Returning to the agreed trump suit (or bidding 3@n) denies
interest in slam.  Any non-agreed suit that meets the above criteria
is another cue bid, and continues to be invitational.  Other options
are Blackwood or jumping directly to slam.\par

\HEADING{Overcalls}
An overcall does not require points, it requires tricks!\par
\startt
\+1y\ > 6(5)+ good cards, 6+ tricks.\\
\+1@n > Same as a 1@n opening.\\
\+2\y > (below 2\x) 6+ good cards, 7+ tricks.\\
\+$n$\y > 0--10 pts, 6+ cards. Defensively weak. $n$-3 tricks
(equal vuln.)  Bid it all now, then shut up.\\
\endt
\heading{More about weak jumps}
After a weak jump overcall, partner should pass\dots\par
\Then
\Heading{Followup Principles}
Bidding game is usually signoff.  Bidding one level beneath game is
usually invitational, and often expresses some slam interest.
