AlsoMorphy v Brunswick & Isouard, Paris 1858; the lesson's game
Morphy's game against the Duke of Brunswick and Count Isouard in the Duke's box at the Théâtre-Italien in autumn 1858, the lesson's through-line, replayed with the boy as Black guessing the Duke's moves; the teacher's flag falls with the mating rook still in his hand.
The game the lesson is built around: Morphy, with his back to the stage, beating a Duke and a Count in a box at the opera in 1858. The boy plays the losing side and guesses the Duke's moves; the teacher runs out of time with the mating rook still under his fingertip. It is real history, outside the series' Y axis.
