The Best and Most Difficult Chess Puzzles Ever

Puzzle 1: Prepare to kick yourself if you use the 'Help' button:

Puzzle 2: I'll give you a hint on this next one, the first promotion is a knight, you'll see why!

Puzzle 3: Another strange occasion...

Puzzle 4: Black had agreed in this game to mirror whites moves. Bad choice! Mate in 4!

Feel free to comment and post your own 'most difficult' chess puzzles.

The first puzzle was hard nice puzzle's

Nice, those are some hard puzzles.  Good job!!!

Yes, well pointed out, just shows how silly black was to agree to copy everything white did!

"En passant" is correct :)

Re: Puzzle #2 - promotion to N is not required . . .

daxelson: But what if 1... Bxg2?

Good job picking these up, has anyone got some of their own 'most difficult?'

Estevon, it's true that the black king can move to h5. But white can simply play Qd3 and avoid the black king run away. After Kh4/Kg4, white plays Qh3# 

easy

mos of he ae unusual puzzles but nice! ^_^

mos of them are unusual puzzles

i mean

for the first one, who would use the 'help' button, it's soooooo easy!

2nd one was very unusual but nice, all the same

puzzle 3 was even more unusual, but cool moves 2 end the game nice and quick

the 4th puzzle was quite silly, why wouldn't the black bishop take the white queen
