Greatest chess puzzles

Please post the greatest puzzles in chess that you have encountered.

Does nobody have any??

I give up..

Maybe a stupid question, but how can i post puzzles? ( on IPad )

You can insert diagrams as everybody does.. But I don't think that people are interested in this anyway..

There are no great puzzles remaining in the world now I think!!

This end-game study is my favorite so far : a study by Gijs van Breukelen

Thank you AngeloPardi.. This is amazing!! Even droidfish couldn't find the solution!!

There are some variation in the move list.

Hehe.. very good.. I think only you have great puzzles!! Thanks..

Thanks but these look like usual tactics trainer puzzle. We want really amazing and creative puzzles like AngeloPardi posted.

WOW - this is one of the most difficult puzzle I ever encountered !

But 4... Nf7+ is not forced. 4.. Kg4 offers more resistance.

Hehe.. I didn't say that those puzzles were bad!! :)

We want more!!

Are there only two great puzzles in the world that Angelopardi already posted here?
