Bergen Drury
Mr. Marty Bergen concluded that a 2 Club response by his partner, who is already a passed hand, could show a 3-card support for the opening Major suit with 10-12 points, and that a 2 Diamond response by his partner, who is already a passed hand, could show a 4-card support for the opening Major suit with 10-12 points.
Bergen Major Suit Raises or Bergen Raises
This conventional method was originally called Bergen Major Suit
Raises, because they were only used after one partner opened a Major suit. This is
a conventional method devised by Mr. Marty Bergen, and was first published
in the ACBL Bridge Bulletin in April 1982. Using the responses of this method, the partner
could show his overall strength and his actual trump length with one bid.
Bergen Over Doubles of 1 No Trump
Mr. Marty
Bergen developed a method of dealing
with an opponent's overcall of a double after a 1 No Trump opening. This method,
when applied, allows the partnership to reach the correct contract even after the
opponents have decided to enter the auction. This method also allows the partnership
to finalize the contract even after a penalty double.
Bergen Over No Trump - DONT - D.O.N.T.
This conventional method was devised and develped by Mr. Marty Bergen. This conventional method is more commonly designated as DONT (Disturbing Opponent's No Trump), and is sometimes written as: D.O.N.T. It is a defense method against 1 No Trump openings: double shows one minor or both Majors; two of a Minor shows that Minor suit and a higher-ranking suit.
Modified DONT
A variation on the original concept conceived by Mr. Marty Bergen.Revised DONT
The origin of this variation is unknown. The original concept was devised by Mr. Marty Bergen and published by Mr. Larry Cohen. The original convention is sometimes referred to as Bergen Over No Trump, but has been accepted into the language of the bridge community as simply D.O.N.T. As with all defense methods, this concept has also been altered, varied, modified, and revised to meet the needs of individual partnerships.
Bergen Over Weak No Trump
Mr. Marty Bergen, an experienced and expert bridge player and bridge author, devised this method to interfere with and enter the bidding auction after opponents opened a Weak No Trump, consisting of a range between 10 to 13 high card points, otherwise known as a mini-Notrump.
Variant of Bergen Over Weak No Trump
The origin of this variation is unknown. The reasoning behind the development of such a variant is the fact that the original version was unable to show the Club suit and a second suit.
BROMAD - Bergen Raise Of Major After Double
As soon as the auction sequence begins it becomes inevitable that the opponents attempt to compete, often with a Takeout Double. The auction has been disturbed, and the relay of information has developed some speed-bumps. In order to overcome this situation, the concept of BROMAD was created to indicate certain holdings and has become a defense method. This concept was developed by Mr. Marty Bergen, bridge player, bridge theorist, bridge author.
Impossible 3 No Trump
Mr. Marty Bergen has suggested using a bid of 3 No Trump during the auction in order to
perform a sacrifice against the opponents, when it appears that the opponents have
a game contract in a suit. The concept is the expectation of not making a contract
of 3 No Trump, and therefore the name of this convention or method.
Jump Cuebids As Transfers
Mr. Marty Bergen developed this conventional method to cover a certain situation which arises after an intervening overcall on the One Level, which is an important element to consider before implementing the jump cuebid as a transfer to 3 No Trump. The concept behind the conventional method is that the overcalling opponent will find himself on lead, leaving him at a distinguished disadvantage.
Two Under Transfer Preempt
This method was devised by Mr. Marty Bergen together with Mr.
Larry Cohen and the convention uses
a Preemptive Opening as an artificial Preempt at the Two Level and also at
the Three Level and higher to indicate a specific suit two ranks higher than
the bid suit. This convention allows the responder to use
the intermediate suit for an attempt at game.
