Development
The process of moving pieces, especially knights and bishops, from their starting squares to active positions early in the game.
Rapid, efficient development is a core opening principle — a player who develops pieces faster than their opponent typically gains a lasting advantage in space, activity, and tempo.
Etymology
The noun development, “a gradual unfolding,” dates from 1756, from the verb develop (1650s, “to unroll, unfold”). The chess metaphor is therefore an unwrapping: an army folded up on its back two ranks is unfurled into the open board. Staunton already uses it as ordinary chess vocabulary in 1847, criticising a move because “the development of his Pieces is somewhat retarded.” By Steinitz (1889) it is a governing principle, appearing about thirty times, and it is pervasive in Lasker's Common Sense in Chess (1896) and Capablanca's Chess Fundamentals (1921). Nimzowitsch made it half of his opening theory, titling Chapter 1 of My System “On the Centre and Development.”
First documented: 1847 — Staunton, The Chess-Player's Handbook (London, 1847)
