11 move sphinx - most difficult chess problem I read somewhere that the Sphinx by an English chess wizard called Blackburn is the most difficult chess problem to solve.
Does anyone know this problem.

What is the most difficult - 2 moves to checkmate - problem?

Some basic searching... ...has turned up nothing matching your question exactly. Blackburne *was* one of the strongest players of his day; but my sense is that the golden age of the (composed) chess problem was yet to come.

I will instead urge you to visit one of my absolute favorite chess sites, by master problem composer and commentator Tim Krabbe. If it exists, you will find it there. Be sure to visit the "Open Chess Diary," but only if you have several hours to spend.

PS: Grand Ayatollah Ali al-Sistani of Iraq has declared that the playing of chess is forbidden, but Krabbe has received a clarification stating that the composition and solving of chess problems is permitted. Just an interesting side-note. See his Open Chess Diary for Feb 2005.

I know it, I know it it is actually called "The Sphynx". I don't know whether it's the hardest puzzle to solve but at 11 moves I would say it is certainly beyond most players. The pieces are positioned as follows:-

White: a2, h5, Bb2, Qf4, and Kg5
Black: a3, b4, f5, g4, h7, Rf8, and Kg8

White to play with mate in eleven moves. I do have the solution but I didn't work it out. If you want the solution send me a private message and I'll send the answer to you. I won't post it as it may discourage readers from trying to work it out the 'old-fashioned way' using that most ancient of computers - the brain.

good luck

How long did solving it take? Now I am not asking anyone to post the answer - but if you did solve it how long did it take you? Has anyone at GK solved it? I think perhaps only players with a ranking range over 2000 can solve it.
