Kc7 works too.
doesn't work, c6 can block the check
what black piece can move to c6? id ont understand
From my own games:
funny mate that I just did in online chess:
#88, #93, #94 are impossible, #96 does Qg7 work also?
How do you make a puzzle ?
you click in this image
I think this should count for 96 mate in 1's.
No, because this situation is impossible (what would have black done juste before ?)
123 has 2 possible mates and 127 is quite impossible :)By the way thanks for the tip apostolis
