1. General Considerations
1.1 Leading a Trump
If you can attack a contract it is
usually best to do so. However, there are times when a trump lead is called for.
Example:
 |
You have:
64 AJ93
AQT5 KJ6 |
 | The bidding goes: [ 1S
Dbl 2S Pass ] : [
4S Pass Pass
Pass ] |
 |
Since leading a side suit is
unattractive, lead a trump here. |
Example:
 | The bidding goes: [ 1H or
1S
Dbl 1NT Pass ] : [
2D Pass Pass
Pass ] |
 |
A great time to lead trumps is when
dummy denies support for a major suit opener. In the above example responder
obviously has fewer than three cards (0, 1 or 2) in the opener’s major.
This is a good time to lead trumps. |
1.2 Leads In Suits Which Include The
Ace
 |
Never underlead an ace against a
suit contract at trick one. |
 |
If you do not have the king, lead
the ace only when:
 |
You are defending against a slam
(except 6 NT). |
 |
Declarer preempted. |
 |
Your ace is singleton. |
 |
Your ace is the only unbid suit
against 5C or 5D. |
 |
Your side promised length and
strength in the suit. |
 |
You have a seven or eight-card
suit. |
|
 |
After trick one, lead the king from
AK. |
1.3 Short Suit Leads
 |
Singletons are invariably good
choices. |
 |
Doubletons are overrated, especially
with one honor. |
 |
The best time to lead a short suit
is with trump control, e.g., A63. |
 |
Avoid a short suit lead:
 |
When you do not need a ruff;
e.g., with trump holdings such as QJ9 and KQT. |
 |
When you have trump length. With
four trumps it is usually correct to lead long suit to make declarer
ruff (this is called a forcing game). |
|
1.4 Basic Leads
In selecting your lead, you must
consider your hand as well as inferences from the bidding.
 |
Desirable Leads
 |
Partner’s suit, especially if
he promised five or six cards. The proper card to lead is the same one
you would have led in any other suit. Therefore lead low from Q63 or
K852. |
 |
Top of a three-card (or longer)
sequence. |
|
 |
Sequences
 |
It is better to lead top of a
sequence than fourth-best (or 3rd & 5th against a suit contract) |
 |
A sequence must contain an honor
(10 or higher) |
 |
Against a suit contract,
a sequence can be as short as two cards. Lead the king from KQ53, and
the queen from QJ64. However, against a notrump contract, lead
low from both holdings. |
|
 |
Partner Has Not Bid And There is no
Sequence
 |
Prefer to lead a suit the
opponents have not shown. In general, try to lead from length against
any contract. A lead from QT74 is more attractive than from QT7. It
is acceptable to lead away from a king against a suit contract. |
|
 |
Leading Dummy’s Suit
 |
Leading through strength is
overrated. Lead dummy’s suit only when partner is likely to have
length and strength behind him. |
|
2. Standard Leads Against Suits (3rd
and 5th) - Preferred
 |
Sequences:
 |
AKx, T9x, KQx,
KJTx, QJx, KT9x, JT9, QT9x, KQT9 |
|
 |
Length Leads With an Honor (X =
honor) - lowest-card lead usually indicates an honor:
 |
Xxx, Xxxx (start
of high-low), Xxxxx (start of low-high) , Xxxxxx (start of
high-low) |
|
 |
Length leads Without an Honor:
 |
xx, xxx (MUD to
indicate no honor), xxxx (start of high-low), xxxxx (start
of low-high), xxxxxx (start of high-low) |
|
 |
Primary signals:
 |
Count is first option |
 |
Attitude is given if count
doesn't make sense |
 |
Suit preference is given if
neither count nor attitude makes sense |
|
3. Standard Leads Against Suits (4th
best) - Not Preferred
 |
Sequences:
 |
AKx, T9x, KQx,
KJTx, QJx, KT9x, JT9, QT9x, KQT9 |
|
 |
Length Leads With an Honor (X =
honor) - Lowest-card lead usually indicates an honor:
 |
Xxx, Xxxx, Xxxxx,
Xxxxxx |
|
 |
Length leads Without an Honor:
 |
xx, xxx (MUD to
indicate no honor), xxxx (MUD), xxxxx (MUD), xxxxxx
(MUD) |
|
 |
Primary signals:
 |
Attitude is first option |
 |
Count is given if attitude
doesn't make sense |
 |
Suit preference is given if
neither attitude nor count makes sense |
|
4. Standard Leads Against Notrumrp
 |
Length Leads ---> 4th best
 |
xx, xxx (MUD), xxxx
(MUD if no honor), xxxxx (MUD if no honor), T9x, KQx,
KJTx, QJx, KT9x, JT9, QT9x, KQT9 |
 |
Primary signals: attitude then
count |
|
 |
AKxx(x) – only against
notrump
 |
K ask for attitude |
|
 |
AKJx(x) – only against
notrump
 |
A ask to unblock honor; if no
honor then give count |
|
5. Journalist Leads – “Ten Promises
and Jack Denies” (Non-Standard)
Usually against notrump, though
some play it against suit contracts. Purpose is to promise or deny one of the top
three honors. Whenever the opening lead is a 10, the leader promises the A, K or
Q and an interior sequence. Whenever a Jack is lead, the leader denies having
the A, K or Q and shows a sequence headed by the Jack.
Used when you have:
 |
A high honor with an interior
sequence – lead the 10 which indicates having the A, K or Q
 |
A “interior sequence” is
defined as QJTx, JT9x or T9xx (98xx is not considered a sequence here). |
|
 |
An interior sequence with nothing
above it – l which denies having the A, K or Q |
Typical hands where a 10 is lead
(“Ten Promises”)
 |
AJT9(x),
AJTx(x), KJT9(x),
KT98(x), QT9x(x)
----- lead the 10 |
 |
but not QJT9(x) or QJTx(x)
----- lead the Q |
Typical hands where the J is lead
(“Jack Denies”)
 |
JT9x(x), JTx(x) ----- lead
the J |
Other leads that deny hold an A, K or
Q
 |
T98(x) or T9x(x) -----
lead the 9 (can’t lead the 10) which promises either the 10
at the head of a sequence with no high honor, or a doubleton 9x. |
6. Rusinow Leads (Non-Standard)
Normally used against suit contracts
and only on the opening lead. Purpose is to remove the ambiguity of the standard
king lead.
When two or more consecutive honors
are held. Lead the second-from-the-top honor.
 |
AKQ(x) or AKx ----- lead
the K |
 |
KQJ(x) or
KQx(x) ----- lead the Q |
 |
QJT(x) or QJx(x) -----
lead the J |
 |
JT9(x) or JTx(x) -----
lead the 10 |
 |
T98(x) or T9x(x) -----
lead the 9 |
 |
For any doubleton honor,
lead the top honor. |
