The Cappelletti convention (also called Hamilton) has been discussed as a method to compete over the opponents’
opening 1NT. Another popular method, created by Marty Bergen, is called DONT. It’s an acronym for Disturb the Opponents’ No Trump.
The purpose of DONT is to be able to compete over the opponents’ opening 1NT with many hands, yet with some safety. The object of interfering is not necessarily to get to game, but to try and find a fit and, at the same time, make it difficult for the opponents to find their own fit.
