Opening repertoire: a practical example
A useful repertoire includes an answer to common first moves, a few important branches, and examples of typical middlegames. It should also contain notes explaining what to do when an opponent leaves the main line early.
How to use the idea in your games
Choose material you can review and understand. Add a new branch after your games reveal a genuine gap, rather than expanding your files merely because a fashionable variation appears online.
A useful study question
Can you explain opening repertoire in your own words, identify it in a position, and describe when the idea does not apply? Test the explanation on a legal board before relying on it.
