This is position number 12 of the book I am studying. Discoveries is the theme.
I find it interesting that so many of these basic tactical ideas are rarely solitary expressions. Most of these do not work with just the "discovery" part of the move. "Line clearing" and " diversions" and "attraction" tactics all play a role to set-up the tactic we are "studying". But we have not studied "line clearing", "diversions" and "attractions" yet. Not sure I am confident that this method is best.
