Vanderbilt Club
Vanderbilt Club was one of the earliest bidding systems in the game of contract bridge. It was devised by Harold S. Vanderbilt, who had in 1925 devised the game itself. It was published by him in 1929. It was the first strong club system. An updated version was published in 1964. As of 2017, it has long been obsolete.[citation needed]
In the Vanderbilt Club system, an opening bid of 1♣ is artificial and forcing, and shows a good hand. A response of 1♦ is an artificial negative. Other bids are "regulation bids". The system was published by Harold S. Vanderbilt in his 1929 book Contract Bridge. It was the first strong club system. An updated version was published in 1964.
Vanderbilt was a very early bridge theorist, because in his 1929 book he explained in detail the reasoning upon which his system was based: "In many Contract hands it is essential that an original bidder be assured of a second opportunity to bid".
The Official Encyclopedia of Bridge has called Vanderbilt's 1929 book one which "made a major contribution to the technical development of the game".
Vanderbilt defines the potential of bridge hands in terms of quick tricks. In summary, Vanderbilt Club is:
Vanderbilt distinguishes between informatory doubles and business doubles, two expressions known from auction bridge. Doubles should be informatory at the one-level; at the two-level if neither you nor your partner has previously bid; and perhaps at the three-level, depending on the player's judgment of the score and the bidding. Doubles should be made more freely in contract than in auction bridge, because the potential profit is greater.
Vanderbilt does not otherwise discuss bidding in contested auctions.
Vanderbilt describes three types of invitations to slam: bidding more than is needed to score game; bidding the opponents' suit; and introducing another strain after the partnership has agreed a strain.
