    File INTRODUCTION The objective of the Alert system is for both pairs at 
    the table to have equal access to all information contained in any auction. 
    In order to meet this goal, it is necessary that all players understand and 
    practice the principles of Full Disclosure and Active Ethics. Ethical bridge 
    players will recognize the obligation to give complete explanations. They 
    will accept the fact that any such information is entirely for the benefit 
    of the opponents, and may not be used to assist their own partnership.  This procedure uses the admittedly "fuzzy" terminology of 
    "highly unusual and unexpected" as the best practical solution to 
    simplifying the Alert Procedure. "Highly unusual and unexpected" should be 
    determined in light of historical usage rather than local geographical 
    usage. To ensure full disclosure, however, at the end of the auction and 
    before the opening lead declarers are encouraged to volunteer to explain the 
    auction (including available inferences).  According to the Laws of Duplicate Contract Bridge: Law 
    40.B. Concealed Partnership Understandings Prohibited  
      A player may not make a call or play based on a special partnership 
      understanding unless an opposing pair may reasonably be expected to 
      understand its meaning, or unless his side discloses the use of such call 
      or play in accordance with the regulations of the sponsoring organization.
       
       Bridge is not a game of secret messages; the auction 
      belongs to everyone at the table. 
  The bidding side has an obligation to disclose its 
      agreements according to the procedures established by ACBL.
 
        
         When asked, the bidding side must give a full 
        explanation of the agreement. Stating the common or popular name of the 
        convention is not sufficient. 
  The opponents need not ask exactly the "right" question.
 
        
         Any request for information should be the trigger. 
        Opponents need only indicate the desire for information - all relevant 
        disclosure should be given automatically. 
  The proper way to ask for information is "please 
      explain."
 
        
         Players who remember that a call requires an Alert 
        but cannot remember the meaning must still Alert. 
  In all Alert situations, Tournament Directors should 
      rule with the spirit of the Alert procedure in mind and not simply by the 
      letter of the law.
 
        
         Players who, by experience or expertise, recognize 
        that their opponents have neglected to Alert a special agreement will be 
        expected to protect themselves. 
  Adjustments for violations are not automatic.
 
         There must have been misinformation. 
  An adjustment will be made only when the 
        misinformation was a direct cause of the damage.
 
          
           Note also that an opponent who actually knows or 
          suspects what is happening, even though not properly informed, may not 
          be entitled to redress if he or she chooses to proceed without 
          clarifying the situation. 
  When an Alert is given, ASK, do not ASSUME.
 ANNOUNCEMENTS
 An announcement is one word or a short phrase which tells 
    the opponents directly the meaning of partner's call. When bidding boxes 
    are used, the "Alert" strip is tapped also.   Announcements are required in the following instances:  
      1. After a natural one notrump opening bid.
 EXAMPLE: A 15-17 1NT opening bid is made. The partner of the bidder will 
      say aloud, "fifteen to seventeen."
 
      4. After a non-forcing opening 1 or 1  for which the opener could have fewer than three cards in the suit opened. 
 After the opening bid, the opening bidder's partner says, "May be short."
 HOW TO ALERT
 Using spoken bidding, the partner of the player making an Alertable call 
    says "Alert."
    Using bidding boxes, an Alert is made by tapping an Alert card on the table 
    or by tapping the Alert strip on the side of the bid box. In addition, the 
    Alerter must say "Alert."
 
 Using screens, ALL Alerts are immediate - there are no delayed Alerts. All 
    Announcements become Alerts.
 
 HOW TO ANNOUNCE
 When Bid Boxes are not in use, the partner says aloud the required spoken 
    statement.
 When Bid Boxes are being used, the Alert strip is tapped and the appropriate 
    spoken statement is made.
 IT IS THE RESPONSIBILITY OF THE ALERTER OR ANNOUNCER TO ENSURE THAT 
    THE OPPONENTS ARE AWARE THAT AN ALERT HAS BEEN MADE.
 WHEN IN DOUBT WHETHER TO ALERT OR NOT, ALERT!
 
 FAILURE TO ALERT OR ANNOUNCE  If partner fails to Alert or Announce, a player may not 
    make any indication during the auction. Showing surprise or discomfort may 
    awaken partner to the error and would be a violation of Law. In addition, a 
    player may not make allowances for partner's error. The auction must 
    continue as if partner had acted properly.  When the auction is over, the declaring side 
    MUST reveal to the defenders, after first calling the Tournament 
    Director, any errors of explanation (including Alerts or Announcements that 
    were omitted) before the opening lead is faced. A defender MUST 
    reveal any of his partner's errors but may NOT do so until after the 
    play has been completed. A defender (or any other player) who 
    becomes aware of his own error or omission should correct it 
    immediately. Again, in either case the Tournament Director should 
    be called first.  TYPES OF ALERTS
 Pre-Alerts
 
      Pre-Alerts are given before the auction period begins 
      on the first board of a round. Pre-Alerts are designed to act as an early 
      warning of any unusual methods for which the opponents may need to 
      prepare. (See Part III.) Additionally, a pre-Alert is required when 
      playing methods permitted by the ACBL Mid-Chart or SuperChart in an event 
      conducted using that chart. Pre-Alerts are given aloud by saying what the 
      systems or methods are. Immediate Alerts  
      Immediate Alerts are given at the time partner makes a 
      call which requires an Alert. These Alerts are given in the form described 
      under How to Alert above. Delayed Alerts  
      Alerts given after the auction is completed for 
      Alertable calls above the level of 3NT starting with the opening bidder's 
      second turn to call. The dummy or declarer Alerts the defenders before the 
      opening lead. The defenders Alert after the opening lead has been made but 
      before it is faced. (See Part X.) PART I: NATURAL CALLS Most natural calls do not require Alerts. If the call promises about the 
    expected strength and shape, no Alert is necessary. Treatments that show 
    unusual strength or shape should be Alerted.  As to length, ACBL accepts as NATURAL any offer to play in a 
    suit for the first time that shows:(1)Three or more cards in a minor suit.
 (2) Four or more cards in a major suit.
 (3) Four or more cards for an overcall in a suit at the one level.
 (4) Five or more cards for a weak two-bid.
 (5) Six or more cards for a three-level preempt.
 
 NOTE: Partnerships whose systems include extremely aggressive methods, such 
    as frequent use of four-card overcalls at the two level or higher, weak 
    two-bids with bad five-card suits, or three-level preempts with bad six-card 
    and/or most five-card suits must pre-Alert the opponents before the 
    round begins.
 A treatment is a natural call that carries a specific 
    message about the suit bid or the general strength of the hand. Agreeing to 
    open five-card majors is a treatment - when you open 1 , 
    partner "knows" you have five or more. This is indeed a message but not an 
    unexpected one, so no Alert is required. Weak jump shifts, on the other 
    hand, are unexpected and therefore Alertable. EXAMPLE: 1 -P-2   
      If the 2 bid promises a spade suit of five or more 
      cards, it is a natural call. The treatment involves the strength that the 
      bid promises. If the call is forcing to game, no Alert is required. If it 
      is weak or invitational, then it must be Alerted. Natural bids that convey an unexpected meaning must be 
    Alerted. This includes strong bids that sound weak, weak bids that sound 
    strong, and all other bids that, by agreement, convey meanings different 
    from, or in addition to, the expected meaning ascribed to them.  EXAMPLE: 1 -P-2   
      If 2 is natural and forcing, promising three or more 
      clubs and 10 or more HCP (including those that are forcing to game), it 
      requires no Alert. This is the expected strength and shape of such a bid. 
      If 2  is non-forcing, it must be Alerted. In general, when the use of conventions leads to 
    unexpected understandings about suit length by negative inference, a natural 
    call becomes Alertable. Some such agreements have become expected and 
    are fairly common, therefore no Alert is required.  EXAMPLES: 1 -P-1   PART II: CONVENTIONS A convention is defined as any call which, by partnership 
    agreement, conveys a meaning not necessarily related to the denomination 
    named or, in the case of a pass, double or redouble, the last denomination 
    named.  Examples of calls deemed to be conventional are: showing 
    support for a previously bid suit and shortness in the bid suit (such as a 
    splinter bid) and bidding your worst suit for takeout.  ALMOST ALL CONVENTIONS MUST BE ALERTED.  In general, conventional calls require an Alert. In ACBL-sponsored 
    events, however, there are some common conventions that do not require an 
    Alert during the auction: Stayman, ace-asking bids, most meanings of 
    cue-bids, strong artificial 2 openings and most doubles, 
    redoubles and passes. Some Alerts are delayed until the auction is 
    completed. (SEE PART X: DELAYED ALERTS.) 1) STAYMAN  No Alert is required for any bid of 2 over partner's 1NT opening or 3  over a 2NT opening if it 
    requests opener to bid a four-card major, regardless of whether the Stayman 
    bidder promises a four-card major. Likewise, a 2  response 
    to Stayman (or a 3  response after 2NT-P-3  ) is not Alterable if it denies a four-card major. 
 EXAMPLE: 1NT-P-2
  and 2NT-P-3  Partnerships 
    do not need to Alert their Stayman bids in order to differentiate between 
    those that promise a four-card major and those that don't. Opponents may 
    assume that an immediate bid of clubs over a natural notrump opening is 
    conventional, asking opener to bid a four-card major, with no guarantee that 
    responder has a four-card major suit. However, when it becomes evident that the two-club bidder 
    either does not have or tends not to have a four-card major, an Alert is 
    required at that time.  EXAMPLE: 1NT - P - 2 - P - 2(x) - P - 
    2NT If the 2NT is or is most likely a raise in notrump without a four-card 
    major, an Alert is required at the time of the 2NT bid. NOTE: A 2NT rebid after a response to a strong 2 opening is deemed to be a strong notrump opening for the purposes of this 
    regulation, as is a 1NT or 2NT rebid after a strong, artificial 1  opening and response. EXAMPLE:       2 -P-2  -P- 2NT-P-3   Alerts are still necessary when the bid is not obviously 
    asking for a major, such as a "checkback" auction where the club bid may be 
    mistaken for one showing a club holding.  EXAMPLE: 1 -P-1  -P- 1NT-P-2   
      If the 2 call is artificial such as asking partner to 
      show a four-card major, it requires an Alert. 2) STRONG, ARTIFICIAL TWO CLUBS  Forcing 2 opening bids, either natural 
    or artificial, do not require an Alert. Intermediate 2  openings, such as those used in Precision systems, must be Alerted. After a strong, artificial 2 opening, an 
    artificial 2  response which is either negative or waiting 
    is not Alertable. Those who play a "semi-automatic" 2  bid 
    do not need to Alert. If 2  guarantees the values for game, 
    or has any meaning other than negative or waiting, it must be Alerted. 3) ACE ASKING BIDS  
      4NT Blackwood (any variety over suits) and 4 Gerber (any variety over notrump) and expected responses thereto do not 
      require an Alert of any kind. All other ace-asking bids and responses 
      require an Alert, but some of these Alerts must be "delayed." Ace-asking bids at the level of 3NT or below and usages 
      on the first round (other than Blackwood and Gerber as described above), 
      require an immediate Alert. Unusual ace-asking bids above the level 
      of 3NT starting with opener's second turn to call require a delayed 
      Alert. EXAMPLES: 1 -P-4  -P- 4     If you have agreed to play 4 as an 
    ace-asking bid, make a delayed Alert! Furthermore, the responses to 4  and to subsequent asking bids require a delayed Alert. 1 -P-4   If this is Gerber, the 1 opener should 
    say "Alert" immediately after the 4  bid. 1 -P-4NT If this 4NT is Blackwood, no Alert or delayed Alert is 
    required.  Normal responses to any variety Blackwood do not require 
    an Alert.  REMEMBER! THE DEFENDERS ALSO HAVE THE RESPONSIBILITY 
    TO MAKE DELAYED ALERTS.  4) CUEBIDS  Most cuebids are not Alertable. However, any cuebid which 
    conveys a very unusual or unexpected meaning still requires an Alert.    PART III: PRE-ALERTS Pre-Alerts are designed to act as an early warning system 
    of any unusual methods for which the opponents may need to prepare. 
    Pre-Alerts must be given before the auction period begins on the first board 
    of a round or match.  1) "TWO-SYSTEM" METHODS  Some pairs vary their system by position, by 
    vulnerability, or a combination of the two. While this is legal, it is also 
    something the opponents may need to know ahead of time. One example of this 
    is agreeing to play a forcing-club system not vulnerable and "two over one" 
    vulnerable.  Minor variations such as varying notrump range or jump 
    overcall strength by vulnerability do not require a pre-Alert. These methods 
    still require normal Announcements (notrump ranges; transfers) or Alerts 
    (forcing Stayman over some notrump ranges) when appropriate.  As an aside, please note that it is not legal to vary 
    your system during a session for subjective reasons, such as the skill level 
    of the opponents which you happen to be playing at the time or which member 
    of the partnership is making the call. You may, of course, alter your 
    defenses in response to the opponents' methods.  2) SYSTEMS BASED ON VERY LIGHT OPENINGS OR OTHER 
    HIGHLY AGGRESSIVE METHODS  If it is your partnership style to routinely open hands 
    with fewer than 11 HCP, preempt with very weak (frequently worse than Qxxxxx) 
    suits, and/or overcalls with fewer than 6 HCP at the one level, the 
    opponents must be pre-Alerted.  3) SYSTEMS THAT MAY BE FUNDAMENTALLY UNFAMILIAR TO THE 
    OPPONENTS  Players are expected to be prepared for the vast majority 
    of systems that they may encounter at the bridge table. Common methods 
    include either strong or weak notrumps with or without five-card majors. The 
    forcing opening bid will most often be an artificial forcing opening of 1 or 2  . When you play a system structured along different 
    agreements than these, you should draw the opponents attention to your 
    convention card before the round begins. In short, if you play a system that 
    most players would not immediately recognize (such as a canapé system) or 
    one the opponents may wish to discuss before the auction begins (a 10-12 1NT 
    range with distributional requirements for minor-suit openings, for 
    example), you are required to pre-Alert the opponents.    PART IV: DOUBLES, REDOUBLES AND PASSES Except for those doubles with highly unusual or unexpected meanings, 
    doubles do not require an Alert.  Passes or redoubles with highly unusual or unexpected 
    meanings require an Alert.    PART V: NOTRUMP OPENINGS, RESPONSES AND REBIDS Conventional notrump openings and overcalls require an 
    Alert.  Systemically unbalanced or conventional 1NT openings or 
    overcalls by an unpassed hand, when permitted, and openings at the two level 
    or higher with an unusual range or conventional meaning require an Alert.
     Natural 1NT opening bids require an Announcement.
     
      EXAMPLE: 1NT (showing 12-14 HCP) Partner says immediately, "twelve to fourteen."
 
 EXAMPLE: 1NT (showing 15-17 HCP)
 Partner says immediately, "fifteen to seventeen."
 EXAMPLE: 1NT (showing 14 HCP with a five-card suit to 
      17- without a five-card suit)Partner says immediately, "fourteen plus to seventeen minus."
 Natural 1NT overcalls in the range of 14 to 19 HCP require neither an 
    Alert nor an Announcement. If the top or bottom limit of the natural notrump 
    overcall is out of that range or conventional by an unpassed hand, an Alert 
    is required.  RESPONSES TO ONE NOTRUMP OPENINGS  1) 2 : If it requires partner to bid a 
    four-card major it is not Alertable; all other uses must be Alerted. 2) 2
  : If natural and non-invitational, it is not Alertable. 
    A transfer to hearts is Announced. All other uses must be Alerted. 3) 2
  : If natural and non-invitational, it is not Alertable. 
    A transfer to spades is Announced. All other uses must be Alerted. 4) 2
  : If natural and non-invitational, it is not Alertable. 
    All other uses must be Alerted. 5) 2NT: If invitational to 3NT, it is not Alertable. All other uses must be 
    Alerted.
 6) 3
  ,  ,  ,  : 
    If natural, they are not Alertable. All other uses must be Alerted, or… 7) 3
  ,  and 4  ,  : 
    If transfers to hearts and spades, respectively, must be Announced. PART VI: OPENING SUIT BIDS, RESPONSES AND REBIDS
       1) 1
  : Not Alertable if natural (three or more cards in 
    minor) and non-forcing. Announceable if fewer than three cards is the only 
    unnatural meaning. Any other meaning must be Alerted (e.g., a Precision 
    opening 1  ). 2) 1
  : Not Alertable if natural (three or more cards in 
    minor) and non-forcing. Announceable if fewer than three cards is the only 
    unnatural meaning. Any other meaning must be Alerted. 3) 1
  ,1  : Not Alertable if natural (four or 
    more cards in major) and non-forcing. (Note that canapé systems must be 
    pre-Alerted and canapé bids must also be Alerted during the auction.) All 
    other meanings are Alertable. 4) 2
  : Not Alertable if strong and forcing, whether natural 
    or artificial. All other meanings are Alertable (e.g., natural and weak or 
    intermediate). 5) 2
  ,2  ,2  : Weak, natural, 
    non-conventional uses do not require an Alert. All other natural or 
    conventional meanings are Alertable.
 RESPONSES TO SUIT BIDS 
 1
  -P-1  : 
      Not Alertable if natural, forcing one round, and does not deny a four- 
      (or five)-card major. All other uses must be Alerted. 1 -P-1  or 1  -P-1  : 
      Not Alertable if it shows four or more cards in the suit bid and is 
      forcing for one round. Note that the fact that you might bypass a longer 
      diamond suit is NOT Alertable. 1 -P-1NT or 1  -P-1NT: 
      Not Alertable if it shows a limited (maximum 11 HCP), balanced hand. 1 -P-1  or 1  -P-1  : 1 -P-1  : 1 -P-1NT: 
      Not Alertable if natural and non-forcing. 
      Announceable if it is 
      forcing or semi-forcing. Alert if it: 1) promises spades or 2) has some 
      other conventional meaning.(Note: Semi-forcing in this case means that opener may pass with a minimum 
      and 5-3-3-2 distribution but otherwise will treat it as a forcing notrump. 
      Passed-hand 1NT responses, unless they cannot be passed, do not require an 
      Announcement.  Also see
      Tech File
 1 -P-1NT: 
      Not Alertable if natural and non-forcing. Announceable if it is forcing 
      or semi-forcing. Other conventional agreements require an Alert. 2 -P-2  OR a 2NT response to a natural, 
    strong two bid: 2 ,  ,  -P-2NT: 
      Not Alertable if it asks for further clarification. Natural, 
      non-forcing 2NT responses to opening two bids must be Alerted.NOTE: A non-forcing suit response to a weak two-bid requires an Alert.
 A simple raise (2
  -P-3  , for example) of a 
      weak two-bid that is invitational or better requires an Alert. Game-forcing natural jump shifts are not Alertable. Other 
    jump shifts (either conventional or natural and weak or intermediate) not in 
    competition must be Alerted. A natural jump shift in competition does not 
    require an Alert regardless of strength.  A natural 2NT response which is invitational or better 
    does not require an Alert.  Two-over-one bids are not Alertable if they are natural 
    and forcing for at least one round. Note that natural two-over-one 
    game-forcing bids are not Alertable.  In general, responses by a passed hand are considered 
    non-forcing and do not require an Alert or Announcement.  OPENER'S REBIDS  A 1NT rebid if strong (may have 16 or more HCP) requires 
    an Alert.  A rebid in a suit that tends to be longer than the 
    opening bid suit (canapé) requires an Alert.  Opener's rebid of two of a minor over partner's forcing 
    or semi-forcing notrump response to a major does not require an Alert if it 
    shows three or more of the suit bid (4-5-2-2 does not require an Alert as 
    long as responder expects three or more cards in the minor).    PART VII: HIGH-LEVEL OPENING BIDS 3 ,3  ,3  ,3  : 
      Natural and preemptive (weak) opening suit bids at the three level are 
      not Alertable. If you commonly preempt at this level with very weak suits 
      (worse than Qxxxxx) or suits of fewer than six cards you must pre-Alert 
      your methods. Intermediate, strong or conventional usage must be Alerted. 3NT: A 3NT opening that promises a strong, balanced hand 
    is not Alertable. Gambling 3NT openings and all other conventional uses must 
    be Alerted.  Natural opening bids at the three level or higher which 
    convey an unusual message regarding HCP range or any other information which 
    might be unexpected to the opponents must be Alerted.  
      EXAMPLE:  EXAMPLE:  EXAMPLE:  
        A natural 3 opening which is stronger than expected 
        since the partnership has agreed to open 2  (a Mid-Chart 
        agreement so the Mid-Chart has to be in effect) with weak minor-suit 
        preempts. REMEMBER! Below game, non-forcing natural suit 
    responses to preemptive openings require an Alert.    PART VIII: OTHER CONSTRUCTIVE CALLS Natural jump raises in competition are not Alertable regardless of 
    strength. In the same vein, natural jump shifts in competition do not 
    require an Alert regardless of strength.    PART IX: DEFENSIVE AND COMPETITIVE CALLS A jump to 2NT to show the minors or the lower unbid suits 
    is not Alertable. A bid of 3NT as unusual must be Alerted. A bid of 4NT is 
    not Alertable as long as the prior bid was by an opponent. Non-jump unusual 
    notrump bids below 4NT, except those made by a passed hand, must be Alerted.
     Natural jump overcalls that are weak do not require an 
    Alert. All other natural and conventional meanings are Alertable. Unusual 
    overcalls, including the tendency to overcall at the two level frequently 
    with a suit of fewer than five cards or with less than two-over-one values 
    (approximately 10 HCP), must be Alerted.    PART X: DELAYED (or POST) ALERTS ALERTABLE CALLS ABOVE THE LEVEL OF 3NT STARTING WITH OPENER'S SECOND 
    TURN TO CALL  Once the auction has progressed to the point that the 
    opening bidder has had the opportunity to make a second call, conventional 
    calls at the four level or higher are not Alerted until the auction is over.
     These DELAYED ALERTS are REQUIRED to be made by the 
    DECLARING side before the opening lead. The DEFENDERS are REQUIRED to Alert 
    declarer AFTER the OPENING LEAD but BEFORE declarer makes a play from dummy 
    (Alerting before the lead is turned face-up and the dummy is spread is 
    best).  The declaring side must make their Delayed Alerts before 
    the opening lead. Defenders wait until they have made the opening lead 
    before they explain calls requiring a Delayed Alert. As with normal Alerts, 
    the partner of the person making the Alertable call is the person who makes 
    the Delayed Alert and explains the agreement.  UNUSUAL CARDING AGREEMENTS  Except for leading low from a doubleton which requires a 
    pre-Alert, carding agreements do not require an Alert of any kind. However, 
    the box on the card in the middle of SPECIAL CARDING [ ] PLEASE ASK must be 
    checked when playing a completely unexpected method or one that is not 
    easily or clearly described by simply checking a box.  DECLARER IS EXPECTED TO EXAMINE AN OPPONENT'S CONVENTION CARD WITHOUT 
    PROMPTING IN ORDER TO ASCERTAIN THEIR DEFENSIVE METHODS.
