Development means getting your pieces off their starting squares and into active positions during the opening — usually your knights and bishops first — so they can actually influence the game. A piece still sitting on its home square is doing nothing; a developed piece is fighting for the center, eyeing targets, and getting ready to attack.
The opening is essentially a race to develop. The plan is simple and it’s the same in almost every game: bring out your minor pieces, control the center, and get your king safe by castling — ideally in the first eight to ten moves. Waste time shuffling one piece around or grabbing a stray pawn, and your opponent gets their whole army out first.
The gap in the diagram is enormous. White has three pieces in play and a safe king; Black has zero pieces developed. In a real game that lead often turns into a winning attack, because White can throw force at Black’s position before Black even gets organized. That’s the whole point of developing quickly — a development lead is a real, cashable advantage, and it’s usually worth more than a pawn.

Frequently asked questions
What should I develop first? Knights and bishops — your minor pieces. Aim them at the center, then castle. Rooks and the queen come later, once the position opens up.
Why shouldn’t I bring my queen out early? An early queen gets chased around by your opponent’s developing pieces. Every time you save her you lose a move (a tempo) — so she falls behind while everyone else catches up.
How many moves should development take? Roughly the first eight to ten. If you’ve got your minor pieces out, castled, and connected your rooks, you’ve developed well.
