Polish Club

Polish Club (Polish: Wspólny Język, literally "Common Language") is a bridge bidding system which was developed in Poland, where it is the most popular bidding system, and which is also used by players of other countries. It is a type of small club system.

In the Polish Club, a 1♣ opening bid is forcing for one round but does not necessarily show a strong hand; in most versions of this system it shows either a weak balanced hand (about 12-14HCP), a natural 1♣ opening or any strong hand. Consequently, bids of 1<span style="color:red;">♦</span>, 1<span style="color:red;">♥</span> and 1♠ are limited to about 18HCP, and also 1<span style="color:red;">♦</span> shows at least four diamonds (five in some versions of the system).

The 2♣ opening is usually reserved to show a limited hand with long clubs and possibly a four-card major, similar to the Precision 2♣ opening.

The following outline of the system is based on that given in System licytacyjny Wspólny Język 2005 - opis skrócony ("Polish Club 2005 - a brief description") by Krzysztof Jassem. The latest version translated into English (Polish Club International, 2010), is available here:

1♣ opening

  1. 12–14 HCP, no 5-card major, no 4-card diamond suit. Five clubs are possible if the hand is balanced. Opener should not bid clubs on the next round – even in competition.
  2. 15–17 HCP, five clubs, unbalanced distribution. Opener bids clubs in the next round.
  3. 18+ HCP, any distribution.

1<span style="color:red;">♦</span> response

  1. negative: 0–8 HCP. In the 7–8 HCP range, Responder should not have a 4-card major (the response of one of a major is 7+ HCP, the 1NT response is 9–11 HCP).
  2. 9–11 unbalanced; either both minors (5-4), or one poor minor. (The hand does not qualify for any of the responses: 1NT, 2 in a minor, 3 in a minor).
  3. 12–16 HCP balanced without a 4-card major. The hand is not suitable for declaring no trumps.
1♣ - 1<span style="color:red;">♦</span>
?
1<span style="color:red;">♥</span>/1♠ = better major (3 cards is possible)
1NT = 18–19 HCP, balanced
2♣ = 15+ HCP, natural
2<span style="color:red;">♦</span> = artificial GF, exclusive of 2-suiter hands
2<span style="color:red;">♥</span>, 2♠, 3♣, 3<span style="color:red;">♦</span> = 5+ in the bid suit, semi-forcing
2NT = 22–24 HCP, balanced
3<span style="color:red;">♥</span>/3♠/4♣ = GF, 2-suiter (5-5):
3<span style="color:red;">♥</span> – with hearts, then Responder’s 3♠ shows preference over hearts, 3NT asks for a minor, 4♣, 4<span style="color:red;">♦</span> are cue bids with agreed hearts, 3♠ – spades and a minor, then 3NT asks for a minor, 4♣, 4<span style="color:red;">♦</span> are cue bids, 4♣ – minors.

1<span style="color:red;">♥</span>/1♠ responses

7+HCP, 4+ cards, can have longer minor if less than GF

1♣ - 1<span style="color:red;">♥</span>/1â™Â
?
2♣ = 15+, one-round force, then Responder’s 2<span style="color:red;">♦</span> forces to game.
2<span style="color:red;">♦</span> = Relay, 18+ HCP, promises at least 3 cards in Responder’s major.
2<span style="color:red;">♥</span> = (After 1♠ response) 5+<span style="color:red;">♥</span>, (18+ HCP), GF
2NT = 18+ HCP, (semi-)balanced, denies 3-card support in Responder’s suit.
After 1♣-1<span style="color:red;">♥</span>/1♠-2<span style="color:red;">♦</span>, Responder bids as follows ("Bubrotka"):
2<span style="color:red;">♥</span> = 7–10 HCP, 4 cards in the bid major
2♠ = 11+ HCP, 4 cards in the bid major
2NT = 11+ HCP, at least 5 cards in the bid major
3♣, 3<span style="color:red;">♦</span> = 9–11 HCP, 5 in the bid minor, 4 in the bid major
3<span style="color:red;">♥</span> = 7–10 HCP, 5 cards, unbalanced (then 3♠ asks for a shortage, 3NT asks for a side suit)
3♠ = 7–10 HCP, 5332 with 5 in the bid major
3NT = 7–10 HCP, 6 cards in the bid major

1NT response

9–11 HCP, no 4-card major

1♣ - 1NT
?
2♣ = natural, 15+ HCP, GF
2<span style="color:red;">♦</span>, 2<span style="color:red;">♥</span>, 2♠ = 5+ cards, 18+ HCP, GF

2♣/2<span style="color:red;">♦</span> responses

5+ cards, GF, can have 4-card major

2<span style="color:red;">♥</span>/2♠ responses

Strong jump shift (semi-solid suit)

2NT response

12+ HCP, GF no 4-card major

3♣/3<span style="color:red;">♦</span> response

Good 6-card suit, invitational (9–11 HCP)

3<span style="color:red;">♥</span>/3♠ responses

7-card suit with 2 high honours, nothing outside

1<span style="color:red;">♦</span> opening

4+ cards, 12–17 HCP possible canape: 4 diamonds; 5 clubs are possible if weak (12–14 HCP)

  • 2♣ response – natural, promises 5 clubs, one-round force. Rebidding diamonds by Opener shows length (5 diamonds) and does not specify strength. The other 2-level bids show 4-card openings in the range of 12–14 HCP.
  • 2<span style="color:red;">♦</span> response – inverted minor, 10+ HCP, 4 diamonds
  • 3<span style="color:red;">♦</span> response – preemptive
  • NT responses: 1NT = 7–10 HCP, 2NT = 11–12 HCP; both deny a 4-card major.

1<span style="color:red;">♥</span>/1♠ openings

5 cards, 12–17 HCP

  • 1NT Response – not forcing

Responder's 2NT is forcing after the suit is repeated. 1<span style="color:red;">♥</span> 1♠/1NT 2<span style="color:red;">♥</span> 2NT = forces to 3 of a major; opener shows shortage, and 1♠ 1NT 2♠ 2NT = forces to 3 of a major; opener shows shortage Two-over-one response – forces to three of that suit.

  • 2♣ response is semi-natural.

Rebidding the suit by Opener shows a minimum and does not show length. 2NT rebid by Opener shows strength (15–17 HCP).

  • 2NT response – limit raise with support
  • Jump raise – preemptive

Two types of Splinter bids 1<span style="color:red;">♥</span> - 3♠ = any shortage, 9–12 HCP (then 3NT asks shortage) 1♠ - 3NT = any shortage, 9–12 HCP (then 4♣ asks shortage) 1<span style="color:red;">♥</span> - 3NT = spade shortage, 12–16 HCP 1<span style="color:red;">♥</span>/1♠ - 4♣, 4<span style="color:red;">♦</span>, 4<span style="color:red;">♥</span> (after 1♠) = bid shortage, 12–16 HCP Drury-fit by a passed hand 2 of the bid major is the weakest rebid. Jump shift by a passed hand – invitational (9–11 HCP)

1NT opening

15–17 HCP

Opener's 2<span style="color:red;">♥</span> does not deny four spades. Responder's subsequent bidding is natural: forcing at the 3-level, non-forcing at the 2-level. Also: 1NT - 2♣; 2<span style="color:red;">♦</span> - 2♠ = invitational (7–9 HCP), 5 spades, 4 hearts, and 1NT - 2♣; 2<span style="color:red;">♥</span>/2♠ - 3<span style="color:red;">♦</span>/3<span style="color:red;">♥</span> = transfer, agrees Opener's suit, GF

  • Jacoby transfers 2<span style="color:red;">♦</span>/2<span style="color:red;">♥</span>

Transfer to hearts (2<span style="color:red;">♦</span>) does not deny five spades. Responder's new suit at the 3-level forces to game. Also: 1NT - 2<span style="color:red;">♦</span>; 2<span style="color:red;">♥</span> - 2♠ forces to 3<span style="color:red;">♥</span> (8+ HCP)

  • 2♠ response – transfer for clubs. Opener may choose between a positive 2NT, and a negative 3♣. Responder may continue by showing shortage.
  • 2NT response – limit
  • 3♣ response – transfer to diamonds, weak or strong Opener is obliged to bid 3<span style="color:red;">♦</span>. Responder may continue by showing shortage.
  • 3<span style="color:red;">♦</span> – natural, inviting
  • 3<span style="color:red;">♥</span>/3♠ – 5431 convention: GF, both minors: at least 5-4, shortage in the bid suit

2♣ opening

Precision: 5 clubs and a 4−card major, or 6 clubs, 11–14 HCP

  • 2<span style="color:red;">♦</span> response – relay, forcing to 3♣. Opener shows a 4-card suit (3<span style="color:red;">♦</span> shows extras) or makes a choice between 2NT and 3♣ with long clubs.
  • 2<span style="color:red;">♥</span>/2♠ response – not forcing, good 5-card suit (7–11 HCP)
  • 2NT response – weak support in clubs or GF two-suiter. Puppet to 3♣. Opener must bid 3♣. Responder either passes or shows his suits: 3<span style="color:red;">♦</span> = diamonds and hearts, 3<span style="color:red;">♥</span> = hearts and spades 3♠ = spades and diamonds.
  • 3♣ response – limit raise (invitational)
  • 3<span style="color:red;">♦</span>/3<span style="color:red;">♥</span>/3♠ response – limit, good 6-card suit

2<span style="color:red;">♦</span> opening

Weak two in a major (limited Multi), 6+ cards, 6–11 HCP.

  • 2<span style="color:red;">♥</span>/2♠/3<span style="color:red;">♥</span>/3♠ response – pass or correct
  • 2NT – relay, forcing to 3 of the major

Opener bids: 3♣ = good opening, 3<span style="color:red;">♦</span> relays and 3<span style="color:red;">♥</span> shows spades. 3♠ shows hearts. 3<span style="color:red;">♦</span> = hearts, minimum opening 3<span style="color:red;">♥</span> = spades, minimum opening

  • 3♣ response – GF, any one-suited hand, puppet to 3<span style="color:red;">♦</span>.
  • 3<span style="color:red;">♦</span> – game-invitational with support in both majors

Opener bids 4♣ with hearts and 4<span style="color:red;">♦</span> with spades if the invitation is accepted.

  • 4♣ response – asks Opener to bids the suit below his major. Opener bid 4<span style="color:red;">♦</span> with hearts and 4<span style="color:red;">♥</span> with spades.
  • 4<span style="color:red;">♦</span> response – asks Opener to bids his suit.
  • 4<span style="color:red;">♥</span>/4♠ response – to play

2<span style="color:red;">♥</span>/2♠ openings

Polish two−suiters, 6–11 HCP.

  • Opening 2<span style="color:red;">♥</span> = any 5-5 with hearts (spades possible)
  • 2♠ response = pass or correct
  • 2NT response – asks for another suit. With hearts and spades Opener bids 3<span style="color:red;">♥</span>. Other responses – natural
  • Opening 2♠ = 5 spades and 5 of a minor

2NT opening

5-5 in minor, 6-11HCP.

  • 3<span style="color:red;">♥</span> asks to bid a longer minor or a longer major if minors are equal.
  • 3♠ – natural, forcing

3NT opening

Gambling (no stopper outside)

  • 4<span style="color:red;">♦</span> asks for singleton.

Conventions in an uncontested auction

Jump shift

Strong, semi−solid suit, slam interest

Fourth suit

Invites to game after an initial one-over-one response. Responder may pass in the subsequent bidding but Opener may not. Fourth suit forces to game after a two-over-one response.

Third suit

If Opener raises the third suit, that promises four cards in the suit and denies a stopper in the unbid suit. 3NT bid by Opener shows four cards in the third suit and promises a stopper in the unbid suit.

Forcing 2NT

Responder's 2NT is forcing after a two-over-one response.

Odwrotka

After a 1♣ opening and a response in a major, 2<span style="color:red;">♦</span> is Odwrotka (a "fit reverse"), that shows an 18+ hand, a fit, and asks responder to describe his hand. Jassem recommends replacing WJ2000's "Odwrotka" with the "Bubrotka" responses above.

2♣ – check back

Weak with clubs or game invitational, or game forcing Opener's rebids:

  • 2<span style="color:red;">♦</span> = minimum opening, no 3-card support
  • 2 in Responder's suit = minimum opening, 3-card support
  • 2 in the other major = nice opening, 3-card support
  • 2NT = nice opening, no 3-card support

Responder's continuations: 3♣ signs off. 2 in the bid major is non-forcing (10–12 HCP). Other bids (including 2NT) are game forcing.

En passant

In an uncontested auction, stoppers are shown. In competition, bidding the opponent's suit asks for a stopper. If opponents bid two suits, bidding the higher-level suit promises stopper in the lower-level suit.

Slam bidding

Roman Key Card Blackwood 1430

5♣ = 1 or 4, 5<span style="color:red;">♦</span> = 0 or 3, 5<span style="color:red;">♥</span> = 2 or 5 no trump queen, 5♠ = 2 and a trump queen, etc.

Exclusion Key Card Blackwood (1430 responses)

After trump agreement, an unusual jump shift at the 5-level (or 4♠ when hearts are agreed) asks for key cards, exclusive of the ace of the bid suit.

Hoyt

The cheapest bid after key cards are shown asks for kings. The next cheapest bid shows no kings, etc.

5NT

Kind of Josephine; asks for the number of high honours (ace, king or queen) in trumps 6♣ = 0, 6<span style="color:red;">♦</span> = 1, etc.

Cue bids

First− and second−round controls are treated as equals

Splinter bids

Weaker and stronger types after 1<span style="color:red;">♥</span>/1♠ openings 1<span style="color:red;">♥</span> – 3♠ = weaker Splinter (9–12 HCP), any shortage, 3NT asks 1<span style="color:red;">♥</span> – 3NT = regular Splinter (12–16 HCP), spade shortage 1♠ – 3NT = weaker Splinter, any shortage, 4♣ asks 1<span style="color:red;">♥</span>/1♠ – 4♣/4<span style="color:red;">♦</span>/4<span style="color:red;">♥</span> = regular Splinters (12–16 HCP)

AutoSplinter

An unusual shift jump agrees bidder's own suit only if partner has not shown any suit.

Six in the Splinter suit

Asks partner to bid the grand slam with a void in the splinter-suit.

Interference after Blackwood

DOPI. Double = 0, pass = 1, the cheapest bid = 2 keycards, etc.

Competitive bidding

Over opponent’s takeout double

  • Jump shift – suit and support (fit showing jump)
  • New suit – forcing at 1-level (except 1<span style="color:red;">♦</span>; see below), non-forcing at 2-level
  • Redouble = 10+ HCP

Opener bids before Responder: this shows a minimum if the bid is cheaper than two in the opening bid, but shows extras otherwise.

  • 1<span style="color:red;">♦</span> response over opponent's double – natural, not forcing
  • Support bidding after partner's 1<span style="color:red;">♥</span>/1♠ opening is doubled:
  • 1NT = 7–9(10) HCP; 3-card support
  • 2NT = limit raise: 4-card support
  • Jump shift shows suit and support.

Over opponent’s overcall

  • New suit is forcing at the level of 1 and 3. New suit is not forcing at the level of 2.
  • Jump raise is pre-emptive.

Support bidding after partner’s 1<span style="color:red;">♥</span>/1♠ opening is overcalled

2NT promises good support (usually 4 cards) and forces to game. Direct cue bid is game-invitational, or game forcing with flat distribution and defensive values.

After partner’s 1NT opening is overcalled

  • Double is negative – part score range.
  • New suit is non-forcing at the two-level, but forcing at the three-level.
  • Lebensohl: either GF with 4 cards in the other major or non-forcing with an unbid suit.

After partner’s 2<span style="color:red;">♦</span>/2<span style="color:red;">♥</span>/2♠ opening is overcalled

  • New suit = pass or correct.
  • Double is for penalties.

Negative double

Through 4<span style="color:red;">♦</span> Negative doubles include, apart from standard agreements, forcing hands with a weak 5-card suit and – after 1<span style="color:red;">♥</span>/1♠ opening – invitational no-trump hands.

When the second defender overcalls

  • Support double. A support double does not show extras but promises offensive values.
  • After a 1♣ opening, double is two-way: either a support double or a stronger variant of the opening.

Defensive bidding

No−trump hands

  • 1NT and 2NT non-jump overcalls – 15–18 HCP with a stopper. Subsequent bidding: the same as after a 1NT opening
  • 1NT re-opening – 12–15 HCP. Subsequent bidding: the same as after a 1NT opening
  • 2NT re-opening – 19–21 HCP Subsequent bidding: similar to after the 1NT opening
  • Jump overcalls – direct: natural, pre−emptive; re−opening: constructive
  • Takeout doubles and strong doubles (17+HCP). Takeout doubles promise three cards in unbid majors and two cards in unbid minors. Equal level conversion shows extras.
  • After partner has doubled 1♣, a 1<span style="color:red;">♦</span> bid is negative, other 1-level suit bids are forcing.

After 2<span style="color:red;">♦</span> artificial opening (Multi or Wilkosz)

Second hand's double is for takeout of spades. Pass and then double after 2<span style="color:red;">♥</span>/3<span style="color:red;">♥</span> in the next round is for takeout of hearts:

2<span style="color:red;">♦</span> dble 2<span style="color:red;">♥</span> dble = responsive
2<span style="color:red;">♦</span> dble 2♠ dble = punitive

Fourth hand's live double is for takeout:

2<span style="color:red;">♦</span> pass 2<span style="color:red;">♥</span>/2♠ dble = takeout of hearts/spades respectively

Direct cue bid

Michaels cue bid – unlimited

Jump cue bid

Jump cue bid shows either a solid suit and asks for a stopper or shows any game-forcing one-suiter hand.

Versus strong 1 NT opening

  • Double shows two suits: 5+ cards in a minor, 4+ cards in a major.
  • 2♣ = major two-suiter
  • 2<span style="color:red;">♦</span> = 6+ card in one major
  • 2<span style="color:red;">♥</span>/2♠ = 5 cards in the bid suit and a 4-card minor

Versus weak 1NT opening

Double is for takeout. Other bids show the same shape as versus a strong no trump and promise opening values.

Other

  • Drury (2♣) promises fit, rebidding the suit is weakest bid.
  • Lebensohl after 2<span style="color:red;">♥</span>/2♠ and partner's double

Leads and signals

  • Leads are 2nd best from bad suits (low from two); 4th best from good suits; top of honours; ace from ace-king, king from king- -queen, etc., except 9 from 109x(x).
  • Signals are upside down throughout. In partner's led suit, count is preferred in suit contracts, attitude is preferred in no trump contracts.
  • Echo against no trump contracts – a small card in declarer's first-played suit (from either hand) accepts the lead. Lavinthal – standard way (discouraging in the suit discarded, suit preference for the other 2 suits).
