When the script runs out
This lesson uses chess positions. Until you have played a little, its board questions are worked examples to read. New to chess? Play your first moves (five minutes), then learn it from the beginning.
Opening principles are what is left when the memorised moves run out. Off the board, going back to the reason becomes a habit only if you practise it there too, as this week’s task asks.
