The historical games and patterns the instructor shows beside the Opera Game (Scholar's Mate, Byrne v Fischer, Réti v Tartakower, Evans v Reshevsky, Kasparov's simul), and the 21 boards of the closing scramble, every one ending with no legal move.

The scramble: the tiles finishing at once (Anderssen v Dufresne, Board 14, Morphy v Brunswick & Isouard, Légal's mate, Kasparov v McDonald, Lasker v Thomas in chalk ...).{E4 29:42}edit
Every tangent the instructor takes is a real game, sourced: a thirteen-year-old leaving his queen, a mate on d8 from Vienna, a desperado rook that forces stalemate, a world champion surprised. In the scramble twenty-one boards finish at once, each with no legal move left.
