Rainbow Lesson #7: Pre-Empts
Preamble
______
Contrary to what other sources may advise, the
purpose of a pre-emptive bid is not to direct a lead,
or help Partner find the best makeable contract. Rather,
pre-empts are a logical extension of the second part of
Ward Rule #2:
______
"Behave politely, bid obnoxiously."
______
Any lead directing or constructive benefit
which derives from pre-empting is purely incidental
to its main goal: taking up as much bidding space as
possible and to make it as difficult as possible for
whichever side holds the balance of power. The
pre-emptor is gambling, then, that the hand belongs
to the opponents. Only a few precautions are taken
against the possibility that Partner is the one with
the requisite 18+ points which might make this hand
ours. We will begin by analyzing the strategies
adopted depending on which seat opening Pre-Emptor
occupies.
Pre-Empts in First Seat
______
Here, a certain amount of discipline is
required because of the real possibility of Partner
holding a powerhouse. However, two opponents have
not bid, and we only have one partner. Hence, the
odds are 2-1 in favour of an opponent having great
strength.
Pre-Empts in Second Seat
______
With one opponent having passed, the odds
have now narrowed to 1-1 (i.e. 50%) that it is
Partner whom we will be shutting out with our
space-consuming pre-emptive opening bid. Hence,
pre-empts in second seat should be the most
disciplined: 6 cards if opening at the 2-level,
7 cards if opening at the 3-level, 7-9 HCPs if
not vulnerable, 8-10 HCPs if vulnerable.
Pre-Empts in Third Seat
______
Here we have the benefit of knowing who
is the only player at the table who might have a
powerful hand (i.e. LHO). Hence, all bets are off
regarding a 3rd seat pre-empt. Pre-Emptor may be
bidding with one card short of the usual total,
and can have as few as 0 HCPs.
Unless vulnerable versus not, open 2
in third seat with this hand. What have
you got to lose? With Partner holding
0-12 HCPs, the opponents have at least
28, enough for game, and may well have
a slam!
|
Pre-Empts in Fourth Seat
______
"Pre-empts" in 4th seat is something of
a misnomer, since we could Pass out the hand!
Hence, opening 2 , 2 , 2 or 3 here endeavours
to "steal" a plus without allowing the opponents
to find the fit in which they may be able to
make a positive score. In other words, this
pre-emptor intends to make the contract bid.
This confidence is based on a good 6+card suit
and 12-13 points. Opener does not want to be
raised (except, perhaps, in competition) by
Responder, and does not envision game chances
(else, open at the one level).
______
Because of the unique nature of the
4th seat opening bid, none of the discussion
which follows pertains to a fourth seat
"pre-emptive" Opener.
Questions
| #1 |
I have often seen experienced players open
a weak 2-bid with a 5-card suit. Is this
recommended in 3rd seat? |
| #2 |
Does an opening pre-empt promise a certain minimum number of top honours in the bid suit? |
General Rules of Pre-Empting
______
- Never open pre-emptively with an opening bid.
- Never pre-empt with 2 Aces.
- Never pre-empt with a 4-card major side suit
in first or second seat.
- With long Diamonds, Hearts or Spades, pre-empt
at the 2-level with six, at the three level
or higher with seven. An opening bid of
3
can show only 6 Clubs.
- Never pre-empt with more than 2 defensive
tricks.
- Tend not to pre-empt with exactly 2 defensive
tricks. Partner may make a "phantom"
sacrifice in your long suit against a
game which turns out not to make.
- Tend not to pre-empt with the Ace in your
long suit (if Partner is short, that
Ace may well set up a ruff for a second
defensive trick).
- Tend not to pre-empt with a void -- especially
a major suit void. This might give you a
ruff...and if they end up in this suit, it
will break as badly as it can for them.
Counting Losers
______
When evaluating your hand for any purpose,
the traditional approach is to count your losers
by always assuming LHO is on lead. This method
is known by various names, but we will call it
the "Culbertson Loser Count" method.
|
Using the Culbertson Loser Count, this
hand will lose one Spade, two Hearts, two
Diamonds and one Club. Six losers.
|
______
The problem with this method is with its
premise. LHO will not be on lead for all thirteen
tricks--at least, we hope LHO won't be on lead for
all 13 tricks! 
______
The Culbertson Loser Count is intended to
be used in conjunction with the Rule of 1, 2 and 3.
______
I suggest, instead, the "Born Loser Count"
method. Simply assume that Partner has no HCPs and
a flattish distribution type, inclugin 4 or 5 cards
in your shortest suit. In this way, the above hand
will lose eight tricks.
______
The Born Loser Count is intended for use
by Hemmingway Pre-emptors and by those considering
a strong 2 opening bid.
______
When applying the "Born Loser Count", always assume
that Partner is shortest (doubleton) in your long suit
and longest (4 or 5 cards) in your short suit with a
flattish hand to create a "worst case" scenario.
______
If you hold: - AKQxxx - AQx - x - AQx assume
that Partner has: - xx - xxx - xxxxx - xxx in
deciding whether to open 2 or 1 . With only 8 sure tricks,
open 1 , not 2 .
______
The most practical and accurate Loser Count is the
Fractional Loser Count, which presumes that Partner is on
lead. Kx is 1-and-a-half losers, Qxx is 2 and 3/4 losers, etc.
The Rule of Two and Three
______
In the old days, pre-emptors adopted the style
that any pre-emptive opening bid promised within two
tricks of the bid if Vulnerable, within three tricks
of the bid if not vulnerable. Presuming that the
opponents had a game, though, this meant that the
pair was willing to for -500 against a non-vulnerable
game that would pay only 400 or 420. For this reason,
conservative theorists abandoned this approach in
favour of the Rule of 1, 2 and 3.
The Rule of One, Two and Three
______
The modern conservative approach is that,
if vulnerable versus non-vulnerable opponents, we
should be with one trick of our pre-empt. At equal
vulnerability, having within two tricks of one's
bid is recommended. Only a favourable vulnerability
(i.e we are not vulnerable, they are vulnerable) are
we advised to have within three tricks of our bid.
______
If playing with a new partner on OKBridge,
assume this rule of 1, 2 and 3 is in effect.
______
This conservative approach accomplished
one feat: it ended the popularity of Fishbein, a
conventional agreement whereby doubles of pre-emptive
opening bids were for Penalty.
Hemmingway Pre-Empts
______
Some players, including Kaltica and KSired,
adopt a much more aggressive approach to pre-empting.
Especially at the top levels of bridge, pre-emptors
use the "52 Pickup" rule as a guideline:
|
Vul vs Not
|
Have within 2 tricks
|
|
Vul vs Vul
|
Have within 3 tricks
|
|
None Vul
|
Have within 4 tricks
|
|
Not Vul vs Vul
|
Have within 5 tricks
|
______
At first glance, the arithmetic doesn't seem
to add up here. Why are we willing to go down more
than they can make for a game?
______
The answer lies in the fact that the opponents
may well have a slam. Also, the modern style of using
takeout Doubles makes it difficult for opponents to
double us for penalty. And if our Partner cannot
provide us with a trick, the chances of the opponents
making a slam skyrockets.
