How can you checkmate with a horse?

Hello guys, today we are gonna talk about ,,How can you checkmate with only one HORSE?". I think that's impossible, but, if you have some conditions, you may win with a horse. Let's see the conditions:

1. You may need to have a very lucky position, like this one(This is an exercise with a mate in 2 moves, you need to solve  this exercise).

 2. You  need to be very good at chess, or you will probably fail this type of checkmate.

3.(Now you say a condition, and the best will be posted in the next post, with the name of the man/woman/child who posted it! So, have luck and  write a good condition!)  (I will  say the name of he winner at the final of August.
