Choosing to never castle in a chess game is usually a recipe for disaster. Delayed castling is somewhat common, but never castling is usually a blunder, and only rarely is it the correct strategy. A King in the center of the board for too long will usually come under attack down the central files. It is said to be “stuck in the center”.
Never castling may be a valid strategy if (a) neither side is safe for the King, and (b) the central files are closed. So in positions with interlocked pawn chains in the middle squares of the board, the King may sometimes hide behind those pawn chains. But even this is not very safe, because the enemy can invade behind the pawn chains from either side of the board. It’s likely to be a fatal strategy in beginner and intermediate games.
Another time when a player may choose not to castle is by moving the King to the side, typically for the "f’ file. In some openings this move is intentional and a way of avoiding a check or a pin, but the goal is not really to “never castle”. The goal there is to “artificially castle” slowly by playing either “g3 and Kg2”, or “h3, Kg1, and h3”. In these ways, the King Rook is freed, and the King is in the corner.
A less common time when a player may choose to play Kf1 rather than castle occurs when the King’s rook has an open file. If the Kingside rook pawn has been advanced early in an attack, and has successfully pried open the Rook file, then it may be better for the King’s rook to be on the open rook file, rather than castle into the center.
Never castling is only for advanced players. Beginners should castle early. Intermediate players might try to Delay Castling or perhaps Artificial Castling. Choosing to never castle is most likely to end in a loss for all but the most advanced players.
