Bidding System Help
This page is for information about systems and conventions. To start with we are including a file that has two systems:
- a basic Acol system
- and a slightly more advanced Bernard Acol system
By having them here, I hope it might make singles more able to agree a system which suits their needs. It also sets the framework of the ‘natural bidding’ of the site. As we discuss conventions on the site, I might add some more files to deal with them.
