Morphy's only known problem.

Ernest Morphy sent it, along with a game, to the New York Clipper on June 10, 1856.

The problem was published in the June 28, 1856 issue.

Sam Lloyd also published the problem in the New York Musical World, April 30, 1859, along with Louis Paulsen's only chess problem.





Morphy's problem is often called his "alleged" problem probably because according to Philip W. Sergeant in Morphy's Games of Chess:

"Mr. A. C. White says of the above, in The White Rook, that he cannot trace it further back than 1888, when Lehrner, editor of the Lesehalle, referred to it as the only problem composed by Morphy. Mr. White adds, 'Seeing the wonderfully subtle mates which Morphy was able to announce in his actual games, the production, if genuine, is also disappointing."

That's probably the source of it's "alleged" status. Lawson, apparently, did better research, as shown above, and the problem is definitely Morphy's.



Ernest Morphy sent this letter to Kieseritsky, then editor of La Régence
It was published in the January 1851 issue -

 "I send you, herewith, a game of chess played on the 28th instant between Mr. R. [Eugene Rousseau] and the young Paul Morphy, my nephew, who is only twelve. This child has never opened a work on chess; he has learnt the game himself by following the parties played between members of his family. In the openings he makes the right moves as if by inspiration; and it is astonishing to note the precision of his calculations in the middle and end game. When seated before the chessboard, his face betrays no agitation even in the most critical position; in such cases he generally whistles an air through his teeth and patiently seeks for the combination to get him out of trouble. Further, he plays three or four severe enough games every Sunday (the only day on which his father allows him to play) without showing the least fatigue."
