Chess is a strategic two-player board game played on an 8×8 board, with each side starting with sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. The objective is to checkmate the opponent's king, meaning the king is in check and has no legal escape from capture. When a player h...
A chess game is conventionally divided into three phases: the opening, the middlegame, and the endgame. The opening covers roughly the first ten to fifteen moves and centers on development, king safety, and laying the foundation for later plans. The middlegame is the phase of tactics, attacks, and positional maneuverin...
After 1.e4 e5, the position is the classic Open Game, where both sides commit a central pawn and the resulting middlegames often feature open lines and tactical play.

Positional play emphasizes maneuvering for lasting advantage...
Endgame play rewards precision and understanding. In king and pawn endgames, opposition arises when two kings face each other across one square (with an odd number of squares between them), and the player who does not have to move often gains critical access to key squares, which are squares whose occupation by the kin...
