Development14 Apr 2015
Development is nothing but building up your pieces and pawns to make yourself ready for the war! Drastic development is done in the opening part of the game itself. But gradual and slow development(maneuvering) keeps happening in the entire game.
A typical development involves,
Occupying the center.
Activating all the pieces towards the center.
Getting the King to safety.
A good development is one that follows the above rules. A good development is shown in the dagram below
