Chess is played on an 8x8 grid between White and Black. White always moves first.
Castling allows you to safeguard your King and activate your Rook in one move. Requirements: Neither the King nor the chosen Rook has moved yet, all squares between them are empty, and the King is not currently in check or passing through check.
When an opposing Pawn moves 2 squares forward from its starting position and lands directly alongside your Pawn, you can capture it diagonally "in passing" on your very next turn.
When a Pawn reaches the furthest rank (8th rank for White, 1st rank for Black), it immediately promotes to a Queen, Rook, Bishop, or Knight of your choice.
