This is what I read not so long ago in a judge’s report: “Problem NN had to be excluded on account of a dual in an additional variation which in the judge's opinion is a strong one.” I started thinking, is there a scale for measuring the “value” of a variation or the “cost” of a dual? Should a judge be guided only by his own convictions when assessing whether a dual is “weak” or “strong”? My reflections led me to the creation of a new Classification of Variations and Duals that I am offering to the readers, in the form of Tables 1 and 2, for their consideration.
