The Best and Most Difficult Chess Puzzles Ever

Yes a difficult one.  Can I post it here?

The last puzzle is a silly one.

You want something difficult?

Solve this:

Add 10 black knights and all necessary white pieces to create a legal position in which white to move either stalemates or loses.  (Yes, it can be done!)

Do you even call the 4th one a puzzle !!!..thats insane...rest were cool.

Your idea is good but possible number of moves reaches 4... Promotin to N, only takes maximum of 3 moves.

ok, going to give it another shot. This is a puzzle by Richard Reti, I took from a book. I still don't get it. Is the puzzle correct or does it have faulty moves by black?

White to move and draw.

The presented soljution was wrong specifically 3 Ke5.  Black should win here with 3...h2!, 4 c7 (4 Kd6 h1=Q, 5 c7 Kb7, 6 Kd7 Qh7+!) 5 Kb7, 5 Kd6 h1=Q, 6Kd7 Qh7+ 

The winning moveshould be 3 Ke7!

This I call a real chess puzzle. I am refering specially to the first one.

The first one is brilliant. 

But 1...g5 doesn't explain it all. It can be either g6-g5 or g7-g5. 

This number one puzzle must be the real puzzle of all times.

very good :-)

There is a puzzle where both sides are about to promote, and when one of them promotes, the ONLY way to win is if you promote to the same piece as him, even if the first one promotes to knight, bishop or rook. This man took 30 years creating this puzzle. Do you know where to find it? Pleas econtact me!

Known as Babson task.

Try to figure out why g6-g5 is impossible. Hint: White king.

i enjoyed them, thanx :) The mirror thing was cool ;)

Thanx

Not optimal, bishop can capture knight in g2 instead of the king.

The fourth one has multiple solutions indeed. However, scholar's mate doesn't work, since Black now has 4... Kd8 with the queen out.

i know some puzzzz
