How does ChessWorld validate moves?

ChessWorld checks every move against the internationally accepted FIDE Official Rules, ensuring only legal moves are allowed.

Which special moves are supported?

All special moves are validated, including en passant, long and short castling, check, checkmate, stalemate, resignation, and mandatory draw conditions.

How does castling and promotion work?

When castling, the system automatically places pieces correctly. For pawn promotion, players can choose Queen, Bishop, Knight, or Rook.

Why is automatic move validation important?

Automatic validation prevents illegal moves, avoids disputes, and ensures smooth gameplay — a major advantage over traditional correspondence chess.

ChessWorld.net, founded in 2000, is an online chess site. Play relaxed, friendly correspondence-style chess — with online daily, turn-based games — at your own pace.
