Connected Pawns refer to a situation in chess where two pawns are on the same file or adjacent files and can support each other. This positioning allows them to advance together, making it difficult for the opponent to attack them effectively. Connected pawns can create strong defensive structures and control key squares on the board. In the endgame, connected pawns become particularly powerful as they can promote to higher-value pieces, such as a queen. Their synergy can also help in creating passed pawns, which are pawns that have no opposing pawns blocking their path to promotion. This strategic advantage can significantly influence the outcome of the game.
