Get your pieces out

In 1858 the American player Paul Morphy played two noblemen, the Duke of Brunswick and Count Isouard, who consulted together, in a box at the opera house in Paris. The game lasted seventeen moves and is still the most replayed lesson in chess.

Its first lesson is development: bring your pieces off the back row quickly. By move 9, Morphy had a knight, both bishops, his queen and castling ready; his opponents still had pieces at home.
