The bridge player sits down at the bridge table, the cards are dealt, the auction begins, and player to your immediate right opens with 1 Club. Bidding systems, over the years of the evolving game of bridge, have been devised to reach the best, the optimum contract by employing first this artificial bid. This opening bid is a forcing bid for the responder with the exception of immediate interference.
In order to find out what this bid means, you must take a look at the Convention Cards. There are many Club Systems available and the intention of this web page is to present as many as possible, which have been devised over the years. The bridge player should know what bidding system their opponents are employing and it would be worth the time and effort of the bridge player to learn of and about these bidding systems.
An attempt has been made to include the bidding system based upon the written material available. If the original bidding system has become outdated for whatever reason, the attempt has been made to present only the opening bids and possible bidding features. These are designated as Opening Bids.
If the Club System is not listed here, you may wish to consult our Main Glossary

Blue Team Club Openings
Blue Team became the popular name for the Italian International Bridge Team, which had many international successes from 1956 to 1975. The captain and the members of the Blue Team devised a bidding system, which is still played today. The Blue Team Club was the result of the efforts of the Italian Bridge Federation, Mr. Carl Alberto Perroux, the team captain, and the team members, who dedicated themselves to the study of the game of bridge.
Blue Team Club System
The Blue Team Club System was mainly devised by Mr. Benito Garozzo. The Blue Team Club System is based on the principle that a 1 Club opening is forcing. The style of this system is called Canape, and this means that the opener can/should bid the short suits before he bids the long suits. Canape is a bidding method in which the opener bids his long suit on his rebid and was developed by Mr. Pierre Albarran from France.
Blue Team Club Responses
As the name implies, the opening will be 1 Club. The significance of this 1 Club opening is that it is defined as 1. forcing, and 2. shows 17 or more points using a 4-3-2-1 count. Sometimes it is also a distributional factor which may define a 1 Club opening with slightly less than 17 points, or a weaker 1 Club opening with exactly 17 points.
Blue Team Roman Responses to Blackwood

A helping hand:

Mr. Linskens led the King, taken by declarer’s Ace. Declarer then led a spade. Mr. Linskens took his Ace, cashed the Queen and led another Spade. Declarer discarded his lone Heart on the King, ruffed his remaining Clubs and claimed.
Mr. Sundby realized immediately after he followed low to the Spades that he should have played the Queen, establishing dummy’s Spades. Mr. Linskens then would have had no choice but to lead a Heart, defeating the contract.
The moral: lend partner a helping hand.
Bridge World Standard Opening Bids
This system was created by consensus of the readers of the Bridge World Magazine, with Edgar Kaplan as editor.
Bridge World Standard 2001 – Revised, Established Version
Bridge World Standard encapsultates common American expert practices, determined by polls, as a set of partnership agreements (and, where there is no consensus, non-agreements). It is used as a framework for problems in the Master Solvers’ Club, by impromptu partnerships, and as a basis for discussion by those who wish to formulate their own system.
Where the experts are in substantial agreement (with close cases decided, when possible, by the votes of Bridge World readers at large), those methods become part of the system. Where there are competing popular approaches, alternative methods, called leaves, are listed.
Bridge World Standard 2001 – Older, Projected Version
A consensus Bidding System developed in 1967 and periodically revised, previously in 1993, and then in 2001. It was based on the majority preferences of 125 leading experts and thousands of Bridge World readers. The methods used in the the system were determined by polls.
A clear expert preference determined the treatment, while close questions were decided by the vote of the readers. Because it is a consensus system, the Bridge World Standard is rarely used by regular partnerships. It is, however, valuable in forming casual partnerships. Compare the Bridge World Standard Opening Bids listed below.
CAB Bridge System

The Economical Forcing System was used in international championships by leading Swedish players such as Mr. Jan Wohlin, Mr. Nils Olaf Lilliehook, and Mr. Gunnar Anulf.

As a result, most of the responses are artificial in meaning.
Efos Opening Bids
The Economic Forcing System introduced new features, especially after a No Trump opening. One of these features is the “Repeated” or Extended Stayman convention. The bidding system is similar to a Relay System in that, after an opening by one partner, the next, cheapest suit bid is considered either natural or a generally forcing bid.
