Puzzlopia is the site, from where I got this puzzle.
A chess maze - the name tells it all - you have to move the green horse, to the yellow spot. But hey, you're a peaceful horse, so you don't attack others; but the other red stuff are not peaceful, so they may attack you. Be aware.
I, the owner of the horse, is a stupid guy. So, instead of moving forward, I decided to backtrack from the solution:
Unless I made a dumb mistake, I think it's impossible to reach the green areas (last and penultimate, and meta, and metameta penultimate moves from the outside). Where I am doing it wrong?
(Anybody with a Google, and a working internet can confirm this is not from an ongoing competition.)
