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.
