how to play chess?

Chess Pieces & Their Moves King (♔/♚) – Moves one square in any direction (horizontally, vertically, or diagonally). Check: If the king is under attack, it must be saved. Checkmate: If the king cannot escape attack, the game ends. Castling: A special move where the king moves two squares toward a rook, and the rook jumps over (only if neither has moved and no pieces block them). Queen (♕/♛) – Moves any number of squares horizontally, vertically, or diagonally. Rook (♖/♜) – Moves any number of squares horizontally or vertically. Involved in castling. Bishop (♗/♝) – Moves any number of squares diagonally. Knight (♘/♞) – Moves in an "L" shape (two squares in one direction, then one square perpendicular). Only piece that can jump over others. Pawn (♙/♟) – Moves forward one square, but captures diagonally forward. First move option: Can move two squares forward. En passant: If a pawn moves two squares past an enemy pawn, it can be captured as if it moved only one. Promotion: If a pawn reaches the opposite side, it can become any other piece (usually a queen). Special Rules Check: When a king is under attack, the player must move to stop the threat. Checkmate: When the king is in check with no legal moves to escape—game over. Stalemate: If a player has no legal moves but is not in check, the game is a draw. Draw: Also occurs by threefold repetition, 50-move rule (no captures/pawn moves in 50 moves), or insufficient material (e.g., king vs. king). Game Objective Win by checkmating the opponent’s king. Draw if neither player can win. 当然可以！国际象棋中的 “吃过路兵”（en passant） 是 pawn（兵）的一种特殊走法，中文通常称为 “吃过路兵” 或 “隘路吃兵”。以下是详细解释： Of course! The "en passant" in chess is a special move of the pawn, often referred to in Chinese as "eating a passer" or "passing a soldier". Here's the detailed explanation: 规则说明： Rule Description: 触发条件 Trigger conditions 当一方的兵 从初始位置（第2行或第7行）一步前进两格 时，如果这个兵落在对方相邻的兵的 同一横线（相邻列），对方可以选择用兵“斜吃”它，仿佛它只走了一格。 When a pawn advances two squares from its initial position (row 2 or row 7), if the pawn lands on the same horizontal line (adjacent column) as the opponent's neighboring pawn, the opponent can choose to "eat" it diagonally with the pawn as if it had only gone one square. 例如： For example: 白兵在 e2，黑兵在 f4。 White pawns are at e2 and black pawns are at f4. 白兵从 e2 → e4（前进两格），此时黑方的 f4 兵可以 斜吃到 e3，同时移除白方的 e4 兵。 White moves from e2 → e4 (two squares), at which point Black's f4 pawn can eat diagonally to e3 and remove White's e4 pawn. 执行时机 Timing of execution 必须立刻吃！如果对方不选择在下一步马上“吃过路兵”，之后就不能再吃。 Must eat it right away! If the other party does not choose to "eat the passerby" right away in the next step, they will not be able to eat again. 限制条件 Restrictions 只有兵能“吃过路兵”，其他棋子不行。 Only pawns can "eat passing soldiers", not other pawns. 被吃的兵必须是因为 第一步前进两格 才触发此规则。 The pawn being eaten must be triggered by the first move two squares. 为什么有这个规则？ Why is there such a rule? 历史上，兵最初只能走一格。后来为了加速开局，允许兵第一步走两格，但为了避免兵借此“绕过”敌方兵的威胁，加入了“吃过路兵”规则，保持战术公平性。 Historically, pawns were initially limited to one block. Later, in order to speed up the start, the pawn was allowed to make two squares in the first step, but in order to prevent the pawn from "bypassing" the threat of the enemy pawn, the rule of "eating the passing pawn" was added to maintain tactical fairness. 中文示例： Chinese example: 黑兵在 c4，白兵在 d2。 The black pawn is on c4 and the white pawn is on d2. 白兵从 d2 → d4（前进两格），黑兵可以 从 c4 斜吃到 d3，吃掉白兵（d4 被移除）。 White creeps go from d2 → d4 (two squares forward), and black creeps can eat diagonally from c4 to d3 and eat white creeps (d4 is removed). 简单来说，就是“趁对方的兵走两格时，用相邻的兵斜吃它，就像它只走了一格”。这个规则容易忽略，但对实战很有用！ 😊 To put it simply, "take advantage of the opponent's pawn to move two squares, eat it diagonally with the adjacent pawn, as if it had only gone one square". This rule is easy to ignore, but useful in real combat! 😊 New chat
