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

In the first one, I can't find the mate. Where is it?

First one took about 20 seconds, second one took longer until someone pointed out theres no co-ordinates. Nice one.

Well, as a hint, the key is to first identify all of the Black king's flight squares....

I really don´t get it... Still looking for that trick. :D

Oooooooooooooooh, ok. :)

First one was 15-20 seconds by the way.

Second one... about 20 minutes?

OK, never mind - I found it.

Mate in one to all the black kings!

First 1, 5 seconds

second, 1 min,

third, 45 seconds (I had the right move faster but didn't see the c7 bishop, so I couldn't figure out how it was mate). It was the only real candidate move though, nothing else even checks all the black kings.

Obviously the board of the second puzzle is orientated not according to black' s view, but according to white's. That' s why i don t like artistic chess problems: have nothing to do with real game...

Lol, in the first one, Fritz 11 took precisely 00:00:00 :P

I took about a minute (too much time checking incorrect moves :P) on the first one, got the second one in a second after laughing my head off. ;)

I hate fantasy positions. That's a clear trick. I was expecting something more natural.

The third one took me straight 2 seconds.

1st one 30 sec....checked again if it was mate....

2nd 1 really got me ... until i saw the comments

it took me about 10 secons for tantales 1
