A guide to the Acol System 
This is a reasonably complete reference guide explaining what bids should
mean in most auctions. There is no "Standard Acol" system, and many of the
treatments of bids will be non-standard in some peoples eyes. It is a
competant players system, not for beginners, although there are many
principles that beginners should know.
