World's Hardest Chess Problem

I've heard a lot of dispute over which chess puzzle or problem is the hardest one ever. I think this is probably the hardest one I've ever seen. lol.

Guess it has no solution.

I've seen this one before.

It must be pretty hard if you don't even know that the hell you're supposed to do. Well if we're going by "white to move and win", then there probably isn't a solution. Or maybe it's Qxe8 or something.

 Incorrect, it has many solutions.

1. 0-0-0! (played at Rook handicap).

Aw, nice going. I was hoping to get everyone worked up over it!

Already happened, I was as mystified as everyone else, hence the remembered solution.

what is the first move ?

Any legal move is the first move! :P

A kind of Zen, may be,,,,,,,,,

i dont that the hardest puzzle you can make (it is hard, but there are so many position (order of n! (Basically n =100 is more than all the atoms millions of time over) ) that you can't say one position is hardest (this is the depth to a force win or tie if a win does not exisit) because there a board that are incomplete)

but as for real problems in real games, and if chess is a draw game, this is the hardest it gets because all other real game position are a sub set of the start position an need to be completed to prove that chess is a draw game (i think).

I may be wrong though

It could be any mate! Fools mate,Scholars mate! There are so many mates because it starts with the starting position!

Hardest puzzle would be Black to move and win.

White can move anywhere, he/she isnt looking for a mate right?
