Victor Johnson - Dealing with Interference over Opening 1NT Bids - September 7, 2020

 

First Step: a partnership agreement that any/all the regular agreements you have for responding to 1NT Opening bids (Stayman - Jacoby Transfer - whatever) are now OFF (they simply go away & you start again from scratch). 

Simplest New Agreement: All bids made by Responder or Opener subsequent to an interfering bid by Opponents are Natural (clubs means clubs, diamonds mean diamonds, and so on). You also need to decide on length (that is, if responder bids diamonds how many are they promising - if opener next bids hearts how many are they promising - and so on). Any subsequent bid of NT by either partner should promise a stopper in opponent's suit. 

Simplest Conventional Agreement: There is a very common & simple conventional agreement new players can easily adopt for use when the interfering bid is 2C (it does not matter if the 2C is natural or a conventional bid). The most descriptive name for this agreement is "Stolen Bid Double", but it goes by other names as well. It should only be used when the interfering bid is 2C (just trust me on this one). 

More Complex Agreements: The Cadillac agreement commonly used by experienced players is a scheme called Lebensohl. Lebensohl, however, is reasonably complicated & I do not recommend it for less experienced players.
