Slightly off topic, but why do you want to make your engine class a subclass of your board class? This seems a little weird from an O.O design perspective as usually subclassing implies an 'is-a' relationship (chess engine is-a chess board?!). More natural to me would be to make the chess board an attribute/data member/instance variable of the chess engine. > >I have two questions: >1.
