Minmax to Negamax convertor:


1. NegaMaxEvaluation = + MinMaxEvaluation;   if the WHITE is on the move.

2. NegaMaxEvaluation = - MinMaxEvaluation;   if the BLACK is on the move.


My suggestion: use MinMax for non-recursive searching algorithm realization and
NegaMax for recursive ones. This could simplify procedures for a little bit.
