Who is the Discovered Attacks poster for?
Discovered Attacks belongs to the Chess section rather than to a school year, because games is not something one grade owns. Anyone learning tactics can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Discovered Attacks poster?
The moving piece can do anything it likes, because the threat comes from behind it. A wall chart earns its place by being glanceable from where the work is happening, so Discovered Attacks belongs on the wall where that games work actually happens, within glancing distance, rather than filed away.
