"Checkers is like everyday life. Checkers involves everything, everything related to daily life is reflected in checkers. Concentration, determination, thinking ahead, relativizing, imagination, aggression, luck, sadness, making mistakes, correcting mistakes, and also psychological aspects. Checkers is complete, but that's only the case when you reach a certain level." (Harm Wiersma)

The sum of these attributes that are present in both the game of checkers, chess, and active business life can be described as "entrepreneurial skills". Just as a checkers player must consider various aspects of the game to succeed, an entrepreneur or professional in the business world must utilize a range of skills to be successful in a competitive and dynamic environment.
