The Strong Club System is a set of bidding conventions and agreements used in the game of contract bridge and is based upon an opening bid of 1♣ as being an artificial forcing bid promising a strong hand.[1] The strong 1 ♣ opening is assigned a minimum strength promising 16 or more high card points. All other bids would therefore be limited to a maximum of 15 high card points. There are several variants of the strong club system and all are classified as artificial because the bids are highly codified.
