Acol is perhaps one of the most natural bidding
systems in the world but it is sufficiently flexible to allow a range
of gadgets to added without any loss to its basic structure.
In club bridge you are likely to meet the following conventional
bids being played, and it would seem logical that you know what
they are. (Whether or not you wish to play them.)
All the conventions outlined here are everyday conventions that
can be played by club players.
NOTE
You can ask the meaning of alerted bids when it is your turn to
bid and if you have a serious intention of
making a bid.
Otherwise wait until the end of the auction.
