IntroductionWarning! This system is beyond the scope of the teaching program of Richard Pavlicek and inappropriate for the great majority of bridge players. It is intended for serious tournament players only, or as a reference for other system writers. If you are a casual player, I suggest you stop reading now and devote your study to more beneficial material.
Throughout these notes, strength requirements, unless specifically designated as high-card points (HCP), are presumed to be high-card points for natural notrump bids and total points (distributional values included) for all other bids.
The following abbreviations and notations are used:
| F | forcing |
| NF | nonforcing |
| I | invitational |
| GF | game forcing |
| M | major suit |
| m | minor suit |
| R | red suit ( or ) |
| um | unbid minor |
| X, Y | an unbid suit |
| P | pass |
| Dbl | double |
| Act | bid or double |
| Any | pass, bid or double |
| Rdbl | redouble |
| Rel | relay |
| Xfr | transfer |

Puppet Stayman
response to 1 NT is a modified version of puppet Stayman. Responder must have at least game interest unless he is able to pass openers rebid of 2
, 2
or 2
.

Memory aid: After the 2 relay responders next suit bid is always artificial. Note that a 2 or 2 bid denies interest in the major bid and denies five cards in the major shown. |

is not available (i.e., if opener bid 3
) then 3
shows 5+ clubs and 4
shows exactly 4 clubs.
If responders L-H-O doubles 2
or bids 2
, the structure is unchanged (assuming no further enemy bid). Opener should make his normal rebid or pass, double or redouble. If responder rebids 2
it is to play (he would have passed 2
).
If either opponent bids 2
or higher (after the Stayman 2
bid), the structure is off and the bidding reverts to a natural style. If opener cannot make his normal rebid, he should pass or double. If responder bids a major suit, he shows 4 cards in that suit (3
could be both majors after a 3
or 3
overcall); this is invitational at 2
or forcing at the 3 level. Opener may raise, return to notrump, or show the other major if appropriate.

Responders Third Bid
2. If opener has raised the fourth suit (or third suit) or indicated a 3-card preference for responders first suit, this does not constitute suit agreement; it simply describes openers hand. It is still up to responder to select the final strain.
3. After a third suit force, if responder bids the fourth suit this is game forcing and implies the ace in that suit.

In subsequent bidding, any rebid in the agreed minor by either partner is nonforcing and shows minimal values for his previous bids. Exception: Removal of 3 NT to 4 of a minor is forcing.
The jump minor raise shows 6-9 points and at least 5 trumps (or 4 good trumps). It is basically preemptive. Raises to the 4 and 5 level are also weak, but indicate freakish distribution.

Fourth Suit Bids in General1. Responders rebid after a 2-over-1 response shows either a natural suit or at least six cards in his first suit. Opener should tend to support responders first suit with a doubleton honor or better.

| West 1 ![]() 2 ![]() | North P P | East 2 ![]() 3 ![]() | South P |
2. Responders rebid after openers reverse after a 1-over-1 response is a waiting bid and implies five cards in responders major suit.

3. Openers or responders third bid in a 1-over-1 or 2-over-1 auction indicates the ace or a splinter. Partner assumes the ace and may bid notrump without a stopper (if hand is suitable). Fourth-suit bidder should not pass 3 NT if his bid was based on a splinter.

4. Openers fourth bid (below 3 NT) in a 1-over-1 or 2-over-1 auction suggests two or three small cards, essentially a nothing bid to keep the possibility of 3 NT alive. In some cases, this may be a repeat of a fourth-suit-forcing bid if it could not be natural.

Passed Hand ModificationsThe following changes apply when responder is a passed hand:
1. A 1-over-1 response may be passed if opener has only 13 points, and should be passed if opener has less. When opener does bid again, his rebids retain their normal meaning.
2. The 1 NT response to a major shows 6-12 points and is intended as forcing. Opener may pass with 13 points, and should pass with less. The bidding continues normally if opener bids again.
3. The 2
response to 1
shows 9-11 HCP and 5+ clubs. Opener should pass with a subminimum opening and may pass with 13 points. If opener does bid again, the system structure is unchanged.
4. The 2
response to a major is reverse Drury. See topic.
5. A 2
response to a major (or 2
over 1
) shows 9-11 HCP and 5+ cards. Opener should pass with a subminimum opening and may pass with 13 points. If opener does bid again, a rebid of the same suit, raise or 2 NT bid shows minimal values and is nonforcing; a new suit or jump bid is forcing (below game). The same is true of responders rebids.
6. The 2 NT response to a minor shows 11-12 points and is invitational to game. Any rebid by opener below game is forcing.
7. The 2 NT response to a major shows a limit raise with an unknown splinter. Rebid structure:
| West P 2 NT | North P P | East 1 M ? | South P |
| Call![]() 3 ![]() 3 after 1 ![]() 3 M | Meaning asks for splinter (3 M shows splinter)demands 3 with splinter; else 4 ![]() no game interest; sign-off |
8. Responders rebid after a 1-over-1 response is affected. A jump or raise to the 3 level is invitational instead of forcing.
9. Responders rebid in a third suit is no longer an artificial force. This is natural and invitational, showing a two-suited hand.
Note: Fourth suit forcing and new minor forcing still apply as a passed hand.

Reverse Drury
response to a major by a passed hand is reverse Drury. It shows either 11+ (good 10) points with 3+ cards in openers major, or 9-11 HCP with a 6+ card club suit. It is forcing.
| West P 2 ![]() | North P P | East 1 M ? | South P |

Negative Doubles

after a minor opening) is a negative double. The strength shown is 6+ at the 1 level; 7+ at the 2 level; 8+ at the 3 level; 9+ at the 4 level. Suit requirements:
| West 1 ![]() | North 1 ![]() | East ? | South |

| West 1 X | North Bid* | East ? | South |
| Call![]() Double New suit Single raise 2 NT 3 NT jump 3 NT nonjump Jump shift Jump raise Cheapest cue* Higher cue* Any jump cue* | Meaning 10+; creates forcing auction 6-9; 6+ (good 5) cards; NF 6-9; NF 9-11; natural with fit; I 12-14; natural with fit; NF 9-14; natural with fit; NF weak weak 10+; raise of suit opened 10+ HCP; 5+ cards in the 4th suit; F 13+; splinter raise; GF |
2. After doubling, if responder next bids a new suit or a suit implied by the enemy, it is natural and forcing below game.
3. If responder passes over the two-suited overcall and later bids a suit implied by the enemy, it is natural and nonforcing.

Competitive Rebids
| West 1 X ? | North any | East 1 Y | South bid |
Call![]() 2 NT nonjump 3 NT jump 3 NT nonjump 3 X nonjump 4 X jump 4 X nonjump 3 Y nonjump 4 Y jump 4 Y nonjump 2 reverse3 lower suit 3 reverse 3 J reverseJump shift | Meaning 17-19 15+; based on 6+ suit 17+ (or 15+ with 6+ suit) 15-17 18-20; I in minor 16-18 14-16 17-20; I if diamonds 16-20; I if diamonds 17+; F (structure off) 15-18; NF 17+; F 19+; 4-6 shape; GF 19+; GF |
Responders rebids after a 1-over-1 response revert to a limit style after any enemy bid. A new suit bid below game is forcing; but raises to the 3 level and jump bids are invitational.

Cue-Bids as Rebids
| West 1 X ? 1 X any 1 X any ? | North any (or) any any (or) any any (etc.) | East Act Act ? Act any | South any any any any |
Call![]() Cue below 3 NT Cue above 3 NT Jump Cue | Meaning nondescript; general GF ace or splinter; fit assured splinter raise |
If the enemy has shown two suits, the first cue-bid below 3 NT implies a stopper in that suit; hence, partner may bid notrump with a stopper in the other suit.
| West 1 X Cue 1 X Cue ? | North any any (or) any any (etc.) | East Act ? Act any | South any any any |
Call![]() Pass double Redouble Raise cue Recue by cuer | Meaning waiting; no clear action ace splinter; fit assured ace; fit assured |
Corollary to above: Openers double-jump raise to 4 of responders major denies control in the enemy suit; else cue twice (ace) or splinter (singleton or void).

Competitive Doubles
| Partner must have acted. |
| Your side has not established a fit. |
| Your side has not bid notrump. |
| You did not pass the doubled suit at your last turn. |
| A forcing auction does not exist. |

2. Double of a raised enemy suit thru 3
, provided the enemy action was direct (doubles of enemy balancing actions are for penalty). This also includes the case of an implied enemy fit, such as an enemy response to a takeout double.

Cooperative Doubles
. (Higher doubles are penalty.)1. A double by a player who bypassed the opportunity to redouble or to make a strength-showing double.
| West 1 ![]() P | North Dbl P | East P Dbl | South 2 ![]() |
| West 1 ![]() P | North 2 ![]() P | East P Dbl | South 2 ![]() |
| West 1 ![]() P Dbl | North P 2 ![]() | East 1 ![]() P | South Dbl P |
Important: Doublers strength is not limited by the failure to act at his previous turn. The above sequences would be ideal with any strong 4-4-3-2 shape (doubleton in partners suit).
Corollary: If you redouble or make a strength-showing double, you are unable to make a cooperative double. If you later double, it requires at least 4 good trumps.
2. A double by the partner of the player who just redoubled or made a strength-showing double. This blends well with the corollary above.

After a 2 NT or higher response, opener should know responders suit, so there is no need to repeat it. The bidding proceeds naturally; any game bid is NF. An immediate 4 NT by opener is regular Blackwood, and a raise to 5 of responders suit (NF) asks for the jack.

All doubles by opener or responder are for penalty. All direct passes are forcing.
A cue-bid of the enemy suit by opener, when responder has not acted, shows 5-4-4-0 shape (or 4-4-4-1 in balancing seat).
Any suit bid by opener, whether responder has acted or not, is forcing below game unless opener bids the same suit twice, in which case responder may pass with nothing.
If responder has not shown values and opener makes a natural, forcing suit rebid, the cheapest bid is artificial and waiting. This applies only once; any subsequent bid is natural.
Any jump suit bid by opener (at his second bid) is ace asking, even if this completes game. The structure is unchanged.

Weak Two Bids
, 2
and 2
are weak two-bids. Range is 5-11 HCP and style is undisciplined but sensible. Good 5 card suits (usually 3 of top 5 cards) are permissible at all vulnerabilities. Decent 5 card suits are permissible at favorable vulnerability.

After a balancing double or suit overcall, respond the same as in direct position except that all point ranges for responder are increased by 2 points. Responsive doubles do not apply. Responses to Michaels and the 3-level cue-bid overcall are similar to direct actions.

Responses to all actions after two enemy bids are the same as or similar to those to the related topic. An exception: Responsive doubles do not apply. The description takeout means that responses should be like those to a takeout double.

Additional Agreements1. Major-suit game try structure
2. Competitive doubles
3. Cooperative doubles
The following defensive actions are changed if the bidder is a passed hand (for obvious reasons):
1. Direct 1 NT overcall is unusual.
2. Any 3 NT overcall is unusual.
3. The 3-level cue-bid overcall (strong 1-suiter) does not exist. Any such bid is natural if a jump or Michaels (takeout) if a nonjump.
1. The double of a raised suit, direct or balancing, is for takeout thru 4
, unless the opponents have bid all four suits naturally.
2. A direct double after three enemy bids is for takeout thru 2
even if just one unbid suit exists (in that event the suit opened is a takeout candidate). Examples:
| West 1 ![]() 1 NT | North P Dbl | East 1 ![]() | South P |
| West 1 ![]() 2 ![]() | North P Dbl | East 1 NT | South P |
| West 1 ![]() 2 ![]() | North P Dbl | East 1 ![]() | South P |
3. A balancing double of a suit bid is for takeout thru 2
, even if just one unbid suit exists.
4. A balancing double of 1 NT is for takeout only if both major suits are unbid. Otherwise it is a penalty suggestion with strength in dummys suit. Examples:
| West 1 ![]() P | North P Dbl | East 1 NT | South P |
| West 1 ![]() P | North P Dbl | East 1 NT | South P |
| West 1 ![]() 1 NT | North P P | East 1 ![]() P | South P Dbl |

A direct double of a 1 NT opening shows 17+ HCP or 14-16 with a good lead. It is optional (leaning toward penalty).
| West 1 NT | North P | East P | South ? |
Call![]() Any bid | Meaning same as direct but may be weaker |
A balancing double shows 14+ HCP, usually with all-around values.
If the opening is a weak notrump (maximum 15 HCP), a double of a Stayman 2
response is not lead-directing. It shows 14+ HCP, similar to a balancing double.

Call![]() Pass Double Other | Meaning prudent with length in X takeout (partner can convert if that was his intention) as in direct position |
Note: The runout defense applies thru the level of 4
(e.g., 1 NT Dbl 4
) and over multiple runouts (e.g., 1 NT Dbl 2
P; 2
) provided we have not acted after our initial double and we have not faced the same suit bid twice. In other words, once we act after our initial double, or a player is confronted with the same denomination twice, all doubles are penalty.

shows spades and another suit (which could be hearts). In either case shape should be at least 5-4 in two suits, or 4-4-4-1.

. This includes weak two-bids, intermediate two-bids (such as the 2
opening in most club systems), and all preemptive bids.Actions in balancing seat have the same meaning as direct actions, but ranges are reduced slightly (about 2 points); hence responder should compensate accordingly. For example, a balancing 2 NT overcall would show 13-16 points instead of 15-18.

If according to the enemy methods a two-suited hand might be 5-4 shape but typically is at least 5-5 shape, this should be ignored. Both suits should be presumed to be 5+ cards for the purpose of determining the meaning of our bids.

Lead-Directing Doubles
1. Double by an unpassed hand of an artificial response (thru 3
) to any natural opening bid is a takeout double of the suit opened. These are takeout doubles:
| West 2 * | North P | East 2 ![]() | South Dbl |
| West 1 ![]() | North P | East 3 * | South Dbl |
| West 2 ![]() | North P | East 3 * | South Dbl |
2. Double by an unpassed hand of a splinter bid as our first action shows length in that suit and suggests a sacrifice bid.
| 1. Leaders suit if both leader and doubler have shown suits |
| 2. Doublers suit |
| 3. Dummys suit unless leader can safely lead his own shown suit |
| 4. Leaders shown suit |
| 5. Leaders weaker major suit |
| 1. A side suit bid by the enemy |
| 2. Leaders longest suit not bid by his side |


General ApproachIn a forcing auction, the first bid after suit agreement is natural if the suit was bid naturally earlier. The last bid in each auction is natural:
| West 1 ![]() 3 ![]() | North P P | East 1 ![]() 4 ![]() | South P |
| West 1 ![]() 2 ![]() 4 ![]() | North P P | East 2 ![]() 3 ![]() | South P P |
| West 1 ![]() 2 ![]() 3 ![]() | North P P | East 2 ![]() 3 ![]() | South P P |
The following bids are recognized as advance control-bids and establish suit agreement (partners suit, or the lower ranking of his two suits) by inference. These bids are just like a raise of a suit; i.e., they do not initiate a control-showing auction.
| 1. A new suit bid beyond 3 NT by a player who has bid notrump |
| 2. A bid in the only remaining unbid suit beyond 3 NT |
| 3. A cue-bid in the enemy suit beyond 3 NT |
A bid in an unagreed suit is a control-bid, even if this suit was naturally bid by you or partner. No further suit agreement is possible.
A control-bid does not require extra strength (only suitable values) unless it forces the partnership beyond game.
Bypassing a particular bid does not deny that control. There are many situations in which it is desirable to show a higher control before a lower one to facilitate subsequent bidding.
A control-bid beyond 5 of the highest agreed suit obviously means that a grand slam is possible. It further implies that no suit remains uncontrolled.

Control-Bids1. If a splinter bid, it shows a singleton or void. If splinter bid is beyond 5 of the agreed trump suit, it shows a void.
2. If bid is a suit naturally shown by partner, it implies the ace or king. It should not be a void or small singleton.
3. If bid is the enemy suit or the only unbid suit, it implies the ace or a splinter (if a splinter bid is impractical). Do not bid this way with the king. Partner should presume the ace and may bid 3 NT without a further stopper; if bid was based on a splinter, do not pass 3 NT.
4. If our side has shown only one suit, it implies the ace or king and length (4+ cards). It should not be based on shortness.
5. If our side has shown exactly two suits, it shows first or second round control (ideally, the king) and it implies no king in the remaining suit. For example:
| West P | North 1 ![]() 3 ![]() | East P P | South 2 ![]() 4 ![]() |
![]() | ![]() |
![]() | 4 3 A Q J 8 5 K Q 4 A 6 2 |
Opener should be encouraged by short clubs and discouraged by short diamonds, not vice versa.
| Rules 4 and 5 apply only to slam tries below game so partner can evaluate his hand better. Slam tries beyond game follow the standard practice of showing first-round control. |
1. The ace if partner splintered in that suit or if the previous bid (by either you or partner) implied the ace or a splinter
2. A void if you splintered in that suit
3. The ace or king if a previous bid implied the ace or king

Blackwood1. As an opening bid
2. As an overcall if the enemy showed only a minor suit
3. If a major suit is agreed
4. If partner has acted, notrump has not been naturally bid (the forcing 1 NT response is not considered natural) and the 4 NT Response for Takeout (see topic) does not apply.
Observe from Rule 4 that these auctions are not Blackwood:
| West 1 ![]() 3 ![]() | North P P | East 2 NT 4 NT | South P |
| West 1 ![]() 2 NT 4 NT | North P P | East 2 ![]() 3 ![]() | South P P |
| West 2 NT 3 ![]() 4 ![]() | North P P P | East 3 ![]() 4 ![]() 4 NT | South P P |
If a player uses Blackwood immediately after making a splinter bid, it is defined as exclusion Blackwood. Asker implies a void in splinter suit, and partner should not show that ace.
1. If one suit is agreed, the agreed suit is the key suit.
2. If two suits are agreed, the higher agreed suit is the key suit.
3. Immediately over our opening bid of 4 of a major, or after a rebid of 4 of a major after our 3 NT opening (strong preempt), the bid major is the key suit.
4. Immediately over our jump overcall of 4 of a major, or over a rebid of 4 of a major after a 3-level cue-bid overcall (strong one-suiter), the bid major is the key suit.
5. If 4 NT is a jump, the last suit shown by our side is the key suit. Exception: If two suits are shown simultaneously (as with the unusual notrump), this does not determine a key suit.
Another exception: After a 2
or higher response to our 2
opening, a jump to 4 NT by opener is regular Blackwood (opener may need to distinguish between A-Q and K-Q).
If a key suit is not determined by the above rules, then standard responses apply (0 or 4 aces, 1 ace, 2 aces, 3 aces). Blackwood bidder may sign off in any contract, except for 5 NT which promises all 4 aces and asks for the number of kings by steps (0, 1, 2, 3, 4).

Gerber
1. A response of 4
(jump or not) to partners 1 NT or 2 NT opening bid or overcall (if system on applies).
2. A jump to 4
over partners last bid of 1 NT or 2 NT.
3. A jump to 4
after a puppet Stayman response when opener has indicated no real suit.
| West 1 NT 2 ![]() | North P P | East 2 ![]() 4 ![]() | South P |
| West 1 NT P | North P P | East 2 ![]() 4 ![]() | South 2 ![]() |
4. A jump to 5
over a natural 3 NT response or rebid, provided clubs have not been naturally shown by our side. Each 5
bid is Gerber:
| West 1 ![]() 5 ![]() | North P | East 3 NT | South P |
| West 1 ![]() 3 NT | North P P | East 2 ![]() 5 ![]() | South P |
| West 2 NT 3 ![]() 3 NT | North P P P | East 3 ![]() 3 ![]() 5 ![]() | South P P |
5. A jump to 5
after a puppet Stayman response to 1 NT or 2 NT provided no major is agreed and clubs have not been naturally shown. Each 5
bid is Gerber:
| West 1 NT 2 ![]() | North P P | East 2 ![]() 5 ![]() | South P |
| West 2 NT 3 ![]() | North P P | East 3 ![]() 5 ![]() | South P |
| West 2 ![]() 2 NT 3 ![]() | North P P P | East 2 ![]() 3 ![]() 5 ![]() | South P P |
If no key suit exists, standard responses apply (0 or 4 aces, 1 ace, 2 aces, 3 aces). Gerber bidder may sign off in any contract, except for the cheapest club continuation, which promises all 4 aces and asks for the number of kings by steps (0, 1, 2, 3, 4).

Gerber bidder may sign off in 4, 5, or 6 of any previously shown suit or in 4 NT, 5 NT, or 6 NT. Especially note: A bid of 5
is not a Gerber continuation if clubs have been previously shown.
Sign-off exception: If the reply showed 1 or 4 key cards and in fact is 4, any rebid below slam (even the key suit) is forcing.

Note: A void suit should not be shown when regular Blackwood applies since it is not clear where Blackwood bidder is headed.

Voluntary Bid of FiveA jump to 5 in a minor is a slam invitation if a bid of 4 in that minor would be forcing.
In either case, the slam invitation asks for:
1. Control in the unbid suit if we have bid three suits
2. Control in the enemy suit if not already shown
3. Good trumps relative to the bidding if the above do not apply
| West | North 5 X | East P | South ? |
Call![]() Pass 5 NT 6 X Other suit | Meaning no control in critical suit guarded king control, usually singleton control-bid; promises first-round control in critical suit |

Note: Step responses skip over the trump suit, which always indicates the weakest response.
If asker continues with 4 NT it is regular Blackwood (not key-card).

Four Notrump Response for Takeout
or 4
, you have not previously acted, partner has not made a weak bid or overcalled an enemy weak bid, and there are at least two unbid suits among
,
and
. Otherwise a 4 NT response is Blackwood.

| West 1 ![]() | North 1 ![]() | East 4 ![]() | South 4 NT |

Five Notrump Bids1. A jump to 5 NT over any balanced notrump bid, provided no real suit has been shown, invites a grand slam. Partner should bid 6 NT with a minimum or 7 NT with a tiptop maximum. A suit bid indicates a good 4+ cards with in-between strength.
2. If a real suit has been shown, a jump to 5 NT over any bid except a natural major-suit bid asks partner to select a slam from the obvious alternatives, with 6 NT being a possibility.
3. A nonjump bid of 5 NT over any bid (including a major) has the same meaning as above, but 6 NT is a possibility only if notrump was previously bid naturally. Otherwise, partner must choose a suit.
4. After a 4 or 5-level enemy preempt, whether partner has bid or not, a bid of 5 NT at your first turn requests partner to choose an unbid suit (cheapest first if there are 3 unbid) with 4 cards (or 3 cards with an honor). Example:
| West 4 ![]() | North 4 ![]() | East P | South 5 NT |
![]() | ![]() |
![]() | 3 2 A Q J 4 3 2 A K J 7 2 |
This bid would normally be interpreted as a grand slam force (trump ask), but the need for an unbid-suit takeout is more important and there is no other way to effect it.

Splinter Raises
2. Jump shift or jump cue-bid after a 2-over-1 response = 16+
4. Double jump rebid of 4 in openers minor after a major suit
rebid at the 1 level = 16+
5. Jump shift or jump cue-bid after a 2-over-1 response = 16+
6. Jump shift to 4 level after a puppet Stayman response to 1 NT
and a major-suit rebid by opener = 13+
7. Jump shift rebid after a 2
response to 2
= 6+
8. Jump shift rebid after a 2
response to 2
= 8+
A control-showing auction is immediately started with a splinter raise unless the raised suit is a minor and partner next bids a previously shown major suit.

Non-Raise Splinter BidsAnother kind of splinter bid is the shape-descriptive variety, usually made by a player who has indicated two suits or one long suit, such as in the Jacoby structure. These bids do not initiate a control-showing auction unless suit agreement has previously occurred.

Splinter Asking Bid

Opening Leads at NotrumpKing from A-K-Q, A-K-J, A-K-10, K-Q-J, K-Q-10, or tripleton A-K-x or K-Q-x.
Queen from A-Q-J, Q-J-10, Q-J-9 or tripleton Q-J-x. Also from K-Q-10-9-x to demand jack unblock.
Jack from A-J-10, K-J-10, J-10-9, J-10-8 or tripleton J-10-x. Also from A-Q-J-x-x or K-Q-J-x-x if count is desired.
Ten from A-Q-10-9, A-10-9, K-10-9, Q-10-9, 10-9-8, 10-9-7 or tripleton 10-9-x. Rarely, A-K-10-9 if king lead is undesirable.
Fourth best from four-card or longer suits. No honor strength is necessarily implied, although a high card may be led from a weak suit if desiring a shift to another suit.
Lowest from A-x-x, K-x-x, Q-x-x, J-x-x or 10-x-x.
Highest from 9-x-x or weaker. Exception: If partner has indicated a 5 card or longer suit (which includes third and fourth-seat major openings, although suspect), lead low from three-small unless you have raised the suit.
Higher from a doubleton.

Opening Leads at Suits
except in a suit originated by partner. (Beyond 4
or in a suit originated by partner lead the king.) Reverse of this procedure shows a doubleton.King from K-Q.
Queen from Q-J.
Jack from K-J-10 or J-10.
Ten from K-10-9, Q-10-9 or 10-9.
Lowest from an odd number of cards.
Third best from an even number of cards. Note that a nine lead could be third best (K-J-9-x) or low (K-J-9) but otherwise must be doubleton or singleton.
Higher from a doubleton.

Leads After Trick OneWhen shifting to another suit at notrump, lead fourth-best to encourage the return or high to discourage the return. At suit contracts, however, follow opening-lead methods for spot cards (low odd, third-best even).

Count SignalsIn giving count, normally play your second highest (if affordable) from four cards and the highest affordable from six cards. Play the indicated card:
| 9 8 6 2 | 10 9 8 2 | J 10 9 2 | Q 10 9 2 |
| Q J 10 3 (if intent is to give count) | J 10 9 7 4 2 |
This method is more helpful in distinguishing between two and four, or between four and six, especially in situations in which the ace is led and dummy has the queen with two or three small cards. Note that the highest outstanding card rules out count from four cards.
Ace against a 5-level or higher suit contract requests attitude.
When the ace of an unbid suit is led at a suit contract and dummy has exactly three cards without the queen, signal attitude.
Ace subsequent to the opening lead requests attitude.
King against notrump requests attitude.
Queen against notrump asks for unblock of the jack or ace; otherwise, it requests attitude.
At notrump, if dummy wins partners opening lead with a singleton ace, king or queen, signal attitude.

Suit Preference SignalsAgainst any contract, if the opening leader leads a suit originated by partner in which partner showed 5+ cards. (Third hand should play a middle card to be neutral.) Note: The suit preference is generally more urgent if leader retains the lead.
Against a suit, if the opening leader leads dummys singleton and retains the lead at trick two. Note that when a king is led (thru 4
), this applies only when third hand has the ace.
When leading or following in a suit that partner is expected to ruff.
Against a suit, when partners opening lead is an obvious singleton and you are not trying to win the trick.
When removing declarers last stopper at notrump.
When playing from insignificant cards in a suit in which declarer has shown out (or will show out on the current trick). Note that strategic plays (unblocking, playing a known card, etc.) should not be interpreted as suit preference.
When following suit or discarding (but not when leading) from insignificant cards after count has been given. For example, in the following two holdings the first play is required to show count, but the order of the subsequent plays is suit preference:
| 6 5 4 | 4-5-6 suggests lower suit; 4-6-5 suggests higher suit |
| 9 5 4 3 | 5-3-4 suggests lower suit; 5-4-3 suggests higher suit |

The Wakeup Signal1. Underleading an ace on the opening lead. (When underleading an ace it is best to lead a false spot card so that partner is less likely to misplay thinking declarer has the ace.)
2. A nonsystemic lead such as the queen from K-Q or the jack from Q-J.
3. A blatantly wasteful or illogical signal such as dropping the king from K-J-x-x when you cannot be short in the suit.

Second Plays in the Same Suit
| K Q x | Continue with the queen |
| K Q J 9 | Continue with the jack |
| K 9 7 4 2 | Next play the 9 (or the 7 if you cannot spare the 9) |
| A 9 8 7 4 2 | Next play the 2 |
| A J 10 9 | Next play the 9* |
*Note that this takes priority over leading the top of a sequence.
Second leads from honor sequences follow the usual practice of playing top-down from short holdings (warning partner not to overtake or unblock) or leading the lowest of equals from long holdings (suggesting an overtake or unblock). Besides the obvious cases, this principle can solve problems like this at notrump (first trick is indicated):

If West gets in and leads the jack, East should unblock the nine (and later the eight); but if West led the ace first, East should not unblock. The situation might be:
| 4 | ||
| A J 6 5 | ![]() | Q 9 8 2 |
| K 10 7 3 |
Here West continues with the ace, and East plays the two (present count). The location of the 10, of course, is not known to West, but he knows that declarer started with four (or two if conceivable) and a trick is not blown by a misguided unblock.

Assume the nine is led. Playing the king then the queen tells partner to unblock. Otherwise, partner should not unblock as declarer may have A-7-x. Also note that if declarer won the first trick, partner could safely lead the eight next if your first play were the king (but not if you played the queen).
