My recollection was that the regulation in the ACBL was "use the warning consistently, either always or never". However, when I searched the references in the ACBLscore TECH files, they say that the warning "should be used all the time" and do not condone the "never" option.
ACBL Tournament regulations and policies:
THE STOP CARD
Players should protect their rights and the opponent's by announcing,
prior to making any subsequent bid that skips one or more levels of
bidding.
Place the stop card so that LHO sees it (the skip bidder is
responsible for gaining LHO's attention). The skip bid is made. The
stop card is replaced in the bidding box.
NOTE: If a player forgets to replace the stop card there is no
penalty. It is each player's responsibility to maintain appropriate
tempo including after a skip bid.
If the stop card is placed on the table and a skip bid is not made,
the director may judge that the bid card was played inadvertently or
not. If the judgment is that the card was played after a "slip of the
mind" therefore with intent, then the situation is a Law 16
(Unauthorized Information) situation, not an insufficient bid -
assuming that the player does not want to make (or did make) a
purposeful correction under Law 25 B.2. An example of this situation
is; 1H - 2D - (after the stop card is displayed) 2S.
SKIP BID REGULATIONS
Skip bid regulations and protocol (with or without STOP card use) are
explained in the POLTRN file, pages 7 & 8.
This is the referenced POLTRN policy:
SKIP BID - WARNINGS
1. How and When Made
Players should protect their rights and the opponent's by announcing,
prior to making any subsequent bid that skips one or more levels of
bidding. Proper procedure is:
a. Place the stop card so that LHO sees it (the skip bidder is
responsible for gaining LHO's attention). b.The skip bid is made.
c.The stop card is replaced in the bidding box.
2. Skip Bidder
The skip bid warning may not be used to alert partner that a
strength-showing bid is being made or not being made. The warning
should be used all the time. The tournament director may assess a
procedural penalty (Law 90) for failure to comply.
3. Opponents of Skip Bidder
a. All Players
When RHO has announced a skip bid, the player following the skip
bidder must wait for a suitable interval (about 10 seconds). In
waiting the player's manner must be one that suggests he is an active
participant in the auction (the hand should be studied during the
pause). Any obvious display of disinterest is most improper.
b. Experienced Players
Experienced players are expected to maintain proper tempo whether a
skip bid is announced or not.
4. Questioning
After a skip bid, players may ask questions but must still pause an
appropriate amount of time for study.
5. Failure to Pause
When a player acts with undue haste or hesitation, the tournament
director may award an adjusted score (Law 16) and/or procedural
penalty (Law 90).
6. Where Used
The warning is effective for all ACBL sanctioned events. For
sanctioned games at clubs, the club may elect to discourage it's use
and require no mandated pause. (Board of Directors - November, 1995)
