Design Pattern dilemma. Strategy seems wrong?
I would like some help/advice on a design pattern or similar I could use for my problem.
I have some shared functionality in my code and I use the Strategy pattern at present. I have a base class
And I am also wrapping IF statements such as IF typeof(_projectSectio) is superior then.
It just feels like bad class design. Both standard and superior share a lot of common functionality but then Superior

What you describe is certainly not the Strategy Pattern. In Strategy all classes (of the strategy) have the same interface.
What you have is inheritance. The 'superior' should derive from 'standard' and then possibly override some virtual functions and add some additional methods and behavior. I am not sure if there is another pattern that can help you. Perhaps the State pattern, but it all depends on your requirements.
Since 'standard' and 'superior' are so very different you would ideally place a single IF statement somewhere in your logic and then have two entirely self-contained components that handle the particular situation. So, you apply some form of refactoring.
Hope this helps.
