If you wish to expand your knowledge of a lot of the bidding systems (known as conventions), that are available to you, we suggest that you click anywhere in this article to bring up the web-site "Bridgebums.com" . This site lists under the heading of "Bidding", an A - Z of conventions that you could ever require. Also at the top of the home page, there are even more options for declarer play, defence & more besides. This is an American site, hence the site name, which means something completely different across the pond. This is not just for what you might wish to play, but also to learn about some conventions that you come across that some of your opponents might play.

• What does their bid actually mean?
• What are its downfalls?
• Can you take any advantage by using this knowledge? 

Enjoy..................  

P.S. Please be aware that some of the more British conventions are not there.

P.P.S. I recently came across "Outback Acol" as a way of playing Bridge. I cannot tell you much about this system, but their bids could be from a hand containing 0 (ZERO) HCP's. Not everything is recorded.............
