What "blockade" means in chess

A blockade is a strategy where a player positions their pieces in such a way that they restrict the movement of their opponent's pieces, often by controlling key squares on the board. The aim of a blockade is to limit the opponent's options and prevent them from executing their plans or developing their position, which can give the player with the blockade a significant advantage. Blockades can be created using a variety of pieces, such as pawns, knights, or bishops, and can be used to control specific areas of the board or to limit the mobility of particular pieces, such as the enemy king.
