Study four published CAISSA endgame positions in clear, button-free diagrams with visual teaching markers.
Compare each board with its lesson summary. Arrows show a candidate route or move; highlighted squares identify the relevant geometry. The diagrams intentionally contain no engine, play mode, hint, solution, or download controls.
The interactive diagrams could not be loaded. The complete textual lessons remain available below.
White to move. Compare the kings on the e-file. The arrow from e4 to d4 shows a candidate sideways route; e4 and e6 mark the opposing kings.
