What is Middlegame?

The middlegame refers to the stage in a game of chess that occurs after the opening phase and before the endgame. It typically starts after the players have developed their pieces and castled. In this stage, the focus often shifts towards setting up attacks, executing tactics, and formulating long-term strategies. Piece development and mobility, king safety, pawn structure, and control of key squares or sectors of the board play a substantial role in determining the game's outcome during the middlegame.
