5. Decisions
A decision is a checker move a cube double that is considered non obvious by the computer. Are consider as obvious the following:

A force moved
A move for witch the Best choice and the worse choice have an equity that are less than 0.001 different
A double Action where the Equity before doubling and after doubling is the same (optional double)
A double Action where the Equity before doubling is 0.200 bigger than the equity after double (obvious non double)
A double action where the Equity before doubling is 0.200 bigger than the equity after drop (obvious Too good to double)
A double action where the Equity before and after double is very negative (This correspond to lost position when trailing a lot in the match)

Are never consider as a obvious:

A double decision resulting in a double
A take decision
