Development: a practical example
Knights and bishops often develop early so that the king can castle and the rooks can connect. Development is not a checklist of occupied squares: a piece placed actively with a clear purpose can be more valuable than several pieces moved without coordination.
How to use the idea in your games
Before chasing a pawn, compare king safety and the number of pieces ready to participate. A lead in development matters most when the position can be opened.
A useful study question
Can you explain development in your own words, identify it in a position, and describe when the idea does not apply? Test the explanation on a legal board before relying on it.
