What worked for me was the old Chessmaster tutorials done by Josh Waitzkin. It gives you structured practice problems around general principles and strategies. It was kind of addicting the way they structured it and made me want to keep going. What I got out of it were the general fundamentals that allow you to perform an opening without using pure memorization, and how to look for tactical advantages in mid game like forks and skewers. Once I finished it I started easily seeing all the opening mistakes other beginners made and won a bunch of games just following the general principles. I’ve tried some other similar tutorials since but it is still the best I’ve used as an interactive tutorial.
