Opening Repository for club players

As I am learning opening, I create opening repository and share it here.
The linked study only shows the first 5 moves, while the actually study contains both
the first 5 moves, and repository chapters. I select the first 5 moves, according to my
own experience. Less than 5 moves might miss the main idea, while more than 5
moves needs more time to exercise and remember the opening repository.
