Checkmate (often shortened to mate) is a game position in chess (and in other board games of the chaturanga family) in which a player's king is in check (threatened with capture) and there is no way to remove the threat. Checkmating the opponent wins the game. In chess the king is never actually captured – the game ends as soon as the king is checkmated. In master and serious amateur play, most players resign an inevitably lost game before being checkmated, and it is considered bad etiquette to continue playing in a completely hopeless position. If a player is not in check but has no legal move, then it is stalemate, and the game immediately ends in a draw. A checkmating move is recorded in algebraic notation using the hash symbol (#) – for example, 34.Qh8#.

Chibi Maruko-chan (ちびまる子ちゃん) is a Japanese manga series written and illustrated by Momoko Sakura. The series depicts the simple, everyday life of Momoko Sakura in the times of when she was a little girl where everyone call her Maruko and her family in suburban Japan in the year 1974. The series is set in the former city of Shimizu, now part of Shizuoka City, birthplace of its author. The first story under the title "Chibi Maruko-chan" was published in the August 1986 edition of the shōjo manga magazine Ribon. Other semi-autobiographical stories by the author had appeared in Ribon and Ribon Original in 1984 and 1985, and were included in the first "Chibi Maruko-chan" tankōbon in 1987. The author first began writing and submitting strips in her final year of senior high school, although Shueisha (the publisher of Ribon and Ribon Original) did not decide to run them until over a year later. The author's intent was to write "essays in manga form"; many stories are inspired by incidents from her own life, and some characters are based on her family and friends. The nostalgic, honest and thoughtful tone of the strip led to its becoming popular among a wider audience. Chibi Maruko-chan was adapted into an anime TV series by Nippon Animation, which originally aired on Fuji Television from January 7, 1990 to September 27, 1992. It has also spawned numerous games, animated films and merchandising, as well as a second TV series running from 1995 to the present. Maruko's style and themes are sometimes compared to the classic comic Sazae-san. In 1989, the manga tied to receive the Kodansha Manga Award for shōjo. As of 2006, the collected volumes of the manga had sold more than 31 million copies in Japan, making it the fifth best-selling shōjo manga ever.
