Problem created by Paul Morphy

White to play and mate in two moves. Problem created by Paul Morphy.

Paul Charles Morphy (June 22, 1837 – July 10, 1884) was an American chess player. He is considered to have been the greatest chess master of his era and an unofficial World Chess Champion. He was a chess prodigy. He was called “The Pride and Sorrow of Chess” because he had a brief and brilliant chess career, but then retired from the game while still young. – Wikipedia

Chess is a family of games. Shogi is considered to be the most challenging. It is mostly played in Japan.

Chess originated in India about 1500 years ago. Mancala and Go are games believed to be more than 4000 years old.

When chess reached Spain about 500 years ago, the prime minister became the modern queen. The castling rule is about 100 years old. Even today changes are being suggested.

With a chess clock a game can last as little as two minutes.

Chess started in India as a game for four people. That is why there are four rooks etc. Family chess is a variant where two play against two on one board with no communication allowed.

Go is considered to be more rewarding, but it is of course a matter of taste.

Some variants of Western chess: abba chess, miniature chess, kriegspiel, traitor chess, suicide chess.
