How long do you take to find this mate in one?

very fast

I've seen this before. So in less than a second

please don't give the solution! :(

You prevent the others to answer.

The question is how long do you take to find the solution and not what is the solution.

Please edit your post and suppress the answer.

thanks :)

Good one. Almost a minute .

It's a mate in one from Kubbel.

15 seconds.

the funny thing is when you say your fast you don't know if it's right

I found the most logical move fast obviously, the checking whether it's truly a mate takes the longest

Took me a bit til i realized i was looking at the board upside down.

Where can I see the solution to know if I'm right?

Chess, the sport of Kings (long, long ago)

This one is a bit more difficult (don't give the solution)

Mate in one move.

Hi, thanks for this nice Input. But the last Puzzle i cant find a way to mate in one!

Both puzzles ''are'' mate in one very good!

(Neither board is upside-down)

It's a trick.  Try naming the squares algebraically.

About 10 seconds for the first one, if white is playing from the bottom (otherwise I don't see it).

Second one about 30 seconds to conclude there is no mate in one.

Edit: oh I get it, it's a trick. Now I see why you didn't put co ordinates on the last one.
