Bidding System Help
Good to know: we will be adding more systems and convention cards in response to Members' requests, so feel free to Contact Us.
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.
