Artificial bidding systems are now permitted on Wednesdays, Fridays and Sundays. However, a Club Member may question the use of an artificial system and request that a decision to allow it or not be made by the Committee. Furthermore, those using artificial systems must provide a viable defense against their system.

The following is based on the ACBL alerts system, but simplified to reflect the fact that most BCCM players play similar systems to each other. The aim is to reduce the frequency of required alerts, while still keeping opponents informed of hidden meanings. This alert system is intended for those playing Standard American, Acol or similar systems.
If you are playing something outside these systems (eg. Precision, very light openings etc.), please make sure you alert if the bid has an unexpected meaning. Don’t forget that you can always ask the meaning of an opponent’s bid at any point in the game whenever it is your turn to bid or play.
To alert, please say the word “alert” so the opponents can hear it. You may also use the alert card if you wish.
No doubles or redoubles require alerting---opponents should besufficiently alert to notice a double or redouble and ask the meaning if necessary.
No cuebids of a suit naturally bid by opponents require alerting. Again, opponents should notice these.
A 2♣ opening which is very strong and artificial is not alertable (a natural 2♣ opening or a 2♣ opening which is agreed to be of lesser strength would be alertable).
An Unusual 2NT jump overcall is not alertable (a natural 2NT jump overcall would be alertable).
For alerts marked with an asterisk, you can either alert when the bid comes up or you can pre-alert. If you pre-alert then you should state what your system isat the beginning of every round. For example, if your 1♣ bid may be short, then you have the choice of stating this before looking at your cards for the first board of the round or, if you prefer, just alerting each 1♣ opening by your partner.
All transfers should be announced. If your partner makes a transfer bid, then say “transfer”. Unless asked, do not explain what it is a transfer to.
Alert if agreed range is outside the following:
*1NT opening: 15-17 HCP
1NT overcall: 15-18 HCP
1NT overcall in balancing seat: 11-14 HCP
2NT opening: 20-21 HCP
3NT opening: 25-27 HCP
Alert unless fully natural (eg. a 2♥ bid overcall after 1NT which shows hearts is not alertable. If your agreement is that it shows both hearts and another suit, it is alertable).
Announce all transfers.
Alert other bids which are not fully natural, except for doubles or a cuebid of opponent’s suit.
Alert responses to strong, artificial 2♣, unless natural.
Alert 2♠ , 2♥ and 2♦ opening bids which are not weak.
Alert rebids after a 2NT response to a weak two (eg. Ogust, feature etc.)
Note that a 2NT asking bid itself is not alertable, just the responses.
Alert all artificial bids above 3NT, except:
If your system includes leading low from a small doubleton, this is subject to a pre-alert (see above for how to pre-alert).
