Forcing Pass, or Thy Opponents Shall Not Steal
In last month’s newsletter we discussed forcing bids. Yet we
have all been in situations where we believe our call of pass
should be forcing, and hope our partner sees it the same way.
Let’s discuss this in more depth. By definition, a Forcing Pass
occurs in a competitive auction and allows our partner to choose
the most profitable option. The options typically include a
choice between rebidding in the agreed suit, doubling opponents'
bid, allowing partner to redouble, jumping with a strong hand,
making a conventional response and the like.
Partnership mis-understandings on the Forcing Pass seem to
occur at all levels, stressing the need for us all to develop
sound agreements. Fundamentally, we find partnership agreements
fall in two camps: Scientists and the Naturalist (some of you
will recall the famous grudge match with this
namesake)
Before we jump in, be aware either approach may employ one of
two distinct methods.
METHOD 1
Bid shows a good offensive hand
Double shows good defensive hand
Pass implies neither of these hands
METHOD 2
Bid shows good offensive hand
Pass shows a fairly good offensive hand
Double implies neither of the above
While many players embrace METHOD 1, some partnerships
(notably Mechkstroth-Rodwell) prefer METHOD 2.
At an rate, while Naturalist methods vary, a typical
agreement might include:
After we open, responder bids at the 2 level and opponents
bid 3 Notrump or above, either partner’s pass is forcing.
Additionally, the Forcing Pass is the strongest action showing
slam interest and at least a second round control.

circuit with his “for hire” clients, always placing in the Top
50 annual Masterpoint ranking. Gene enjoys successes as a
Naturalist, generously sharing his Forcing Pass approach with us
here (contact Gene at 415-250-2488, gsimpsongene@yahoo.com):
A. Forcing passes apply when your side bids a game or higher
and the other side sacrifices:
1. You bid a vulnerable game
2. You bid a non vulnerable game voluntarily
3. The opponents have preempted
B. There are five options at the 5 level:
1. Cuebid is a slam try - strongest action
2. Pass and pull partners double - also a slam try
3. Bid 5 level - extra values but no slam interest
4. Pass – offers partner to bid five with extra values
5. Double - worst hand based on auction
C. Cuebid with an outstanding hand, showing first round
control and interest in slam.
D. “Pass and pull” is uncommon. Be aware when you pass,
partner doubles, you need to pass unless you have slam interest
On the side of the Scientists, in the
Okbridge “Spectator” Marc Smith featured a series of
Forcing Pass articles (6/01, 12/01, 1/02). Another Scientist,
Eddie Kantar authored the definitive
Forcing Pass book and wrote a series of articles for
Bridge Today (2/05, 3/05, 5/05). Augie Boehm's
Private Sessions book also has useful theory on conventional
uses of the pass.
Naturally, Scientists methods for Forcing Pass bids vary
considerably, possibly including:
1. Opponents have made an obvious sacrifice bid
2. Your side has voluntarily bid game based on strength, not
merely distributional values. This is particularly true when
partner's pass allows you to evaluate the tradeoffs of doubling
for penalty, especially when opponents are vulnerable, as
opposed to bidding at a higher level - perhaps exploring slam
3. After 3 or 4 level opening preempt by Left Hand Opponent
in first or second seat, double by partner, game raise by Right
Hand Opponent, our pass is forcing except when opponents are
vulnerable (assuming a sane RHO has values)
4. Your side has established a baseline contract level
exploring game or slam, but not yet reached that threshold and
opponents have interceded in the auction
5. A pass over opponents' high level obstructive bid
typically shows a first round control (Ace or void). The
threshold for “high level” may be the 5 or 6 level, depending on
agreements
6. Opponents have doubled a cuebid on your side
7. Opponents are retreating by bidding multiple suits
(usually up the line), where your partnership has repeatedly
doubled
8. Pulling partner's penalty double shows strong interest in
slam
Scientists have more scenarios (and memory work) with less
catch-all guidelines such as a universal “whenever opponents bid
above our 3 Spade call and our bids are constructive, our
subsequent pass is forcing.” Regardless of your approach,
consider
Environmental Factors – particularly vulnerability, freak
distribution, and offensive/defensive tricks.
Here are several common situations:
2C – (any) – P – (any);
P
When opener has near-game values such as a strong 2 Club
opener showing 22+ points, many play a subsequent pass is a
Forcing Bid; lacking a better bid, responder can double to keep
the auction alive. However, when opener begins with a 2 Notrump
bid showing 20-21 point, subsequent passes are not forcing.
1S – (P) – 2N – (3D)
P
Responder’s 2 Notrump bid is game-forcing so opener's pass is
forcing. Note – see
Jacoby 2 Notrump to review alternative methods after
interference
1D – (1H) – 1S – (P);
3D – (3H) – 3S – (4H);
P
Assuming you recognize responder’s 3S rebid as establishing a
game force (opener jumps, responder rebids own suit), opener is
making a Forcing Pass inviting responder to double or bid 4S
with great Spades.
1D – (1S) – 2D – (2S);
1H – (2D) – 2H – (3D);
Here, opener can make a forcing bid by cuebidding opponents’
suit or calling a new suit. When opener (the stronger hand) bids
a new suit at the 3 level, the call is invitational. Jumping in
a new suit at the 4 level subsequently establishes a Forcing
Pass if necessary. Opener’s jump to game has the same effect.
Note: some play this treatment only with adverse vulnerability
based on the risk-reward differential. At any rate, if opener
takes another path, as rebidding at the 3 level, belated opener
passes are not forcing. Note: many also play
Maximal Doubles at the 3 level.
Yet rules like this one should not be thought of as
iron-clad. Contrast these bids:
W N E S
1H – (1S) – 2H – (2S);
4H – (P) - P - (4S);
P
1H – (2C) – 2H – (3C);
4H - (P) - P - (5C);
P
It is unlikely South is “walking
the dog” with extra values on the above auctions. Apparently
South is making a sacrifice bid so opener’s pass is definitely a
Forcing Bid in these auctions. However, South may indeed be
walking the dog on this auction:
W N E S
1H – (P) – 2H – (2S);
3D – (P) – 4H – (4S);
P
The responder may be bidding game based on an anticipated
double fit in the red suits after opener's
Help Suit Game Try. Realizing this, opponent South may
upgrade a two-suited black hand and solely bid game. Thus, the
meaning of opener’s pass will vary by partnership agreement
(again, some play forcing only with adverse vulnerability). As
an aside, when your side bids a lower suit rank as Hearts over
their Spades, it may not be wise to “advertise” a possible
double fit – smart opponents certainly enjoy such useful
information.
In some situations, the Scientists liberalize their
conventional gadgets to replace the meaning of the Forcing Pass
or even the double. Consider this auction:
W N E S
-- -- (P) - P
(1D) - 1H - (2H) - P
(3C) - 4H - (P) - P
(5D) - ?
Should a double be purely for penalty here, or is it a
cooperative (optional) double asking partner to consider a 5H
sacrifice with an offensive hand? Scientists point out the 1H
overcall shows defensive values, not immediately making a
preemptive jump to 4H. So a common treatment is “DSI”,
asking partner to Do Something Intelligent! That is, “Partner,
with defensive values of your own, let the double ride,
otherwise think strongly about supporting my suit.”
So we've seen the Forcing Pass agreements can have many
subtleties, particularly for the Scientists. Regardless of your
approach, be sure your partnerships have clear agreements.
Finally, here's what the
Bridge World Standard says about the Forcing Pass:
1) If a two-club opening is overcalled, responder’s pass is
forcing at every level - responder’s double shows
double-negative strength
2) When a forcing bid is doubled and there is no contrary
explicit system agreement or logic from the auction, a pass is
forcing and a redouble is to play (suggests a contract)
3) After a negative response to two clubs and an overcall,
opener’s pass is forcing
4) After 1any - (X) - XX - (bid); opener’s (or responder’s)
pass is forcing everywhere
