The origin of this conventional defense method is unknown, but this defense method was popularized and promoted by Mr. Anthony (Tony) R. Forrester of Upton Bishop, England. It is for this reason that his photograph is also included in this presentation.

It is a defensive bidding system employed after strong, artificial 1 Club openings. All intervening bids are normally based on a holding with a minimum of 12/13 high card points and on a longer suit of good to excellent quality.

Mr. Anthony R. Forrester, born in the year 1953, is a bridge player and bridge author from England. He is a British and English International Master. He has won the Gold Cup, the premier British teams competition, 11 times: in 1983, 1986, 1989, 1990, 1992, 1993, 2000, 2001, 2007, 2009, and 2012.

     

Principles of the Trap Defense Method

The intervening bids are shown below. All continuances are considered to be a matter to be decided by the partnership. See also variation: Modified Trap Defense. All overcalls are competitive overcalls following an opening bid of 1 Club, which is explained as an artificial 1 Club opening bid, which may have multiple meanings.

Double: A transfer to a long one-suiter in Hearts.
1 : A transfer to a long one-suiter in Spades.
1 : Promises a two-suited holding with Clubs and Spades (black suits) or Diamonds and Hearts (red suits).
1 : Promises a two-suited holding with Hearts and Spades (Major suits) or Clubs and Diamonds (Minor suits).
1 NT: Promises a two-suited holding with Clubs and Hearts (rounded two-suiter) or Diamonds and Spades (pointed two-suiter).
2 : Promises either a one-suited holding in Clubs (the bid suit), of a three-suited holding with shortness in Clubs (the bid suit).
2 : Promises either a one-suited holding in Diamonds (the bid suit), of a three-suited holding with shortness in Diamonds (the bid suit).
2 : Promises either a one-suited holding in Hearts (the bid suit), of a three-suited holding with shortness in Hearts (the bid suit).
2 : Promises either a one-suited holding in Spades (the bid suit), of a three-suited holding with shortness in Spades (the bid suit).

The transfer bids are considered constructive and should be based on a good, positive suit. The holding should contain at least the minimum of a 12 point count.
