Chess

Skycally's Chess lets you play a full game of chess against a built-in AI opponent, directly in your browser with no download or account required. Choose whether to play as White or Black before starting, then click any of your pieces to see every legal move highlighted — click a destination square to play. The AI responds automatically using a minimax engine with alpha-beta pruning and positional evaluation.

The game enforces all standard chess rules: castling (kingside and queenside), en passant captures, pawn promotion with a choice of queen, rook, bishop, or knight, and check and checkmate detection. Illegal moves are automatically prevented, so you can focus on strategy rather than rules. A check warning highlights when your king is under attack.

Choose your side at the start: White goes first by convention, while Black plays a reactive game responding to the AI's opening. When playing as Black, the board flips automatically so your pieces are always at the bottom — a standard orientation used in competitive chess. You can start a new game at any time using the New Game button.

Chess is one of the oldest and most played strategy games in the world, with a history spanning over 1,500 years. It develops critical thinking, pattern recognition, planning ahead, and tactical awareness. Whether you're a beginner learning the basics or an intermediate player looking for practice, this browser-based opponent provides a consistent, available challenge at any time.
