If you can't solve this one, you have no place to go

@Arisktotle is the master of chess-compositions.

Thx, but actually I am not! Master and Grandmasters titles for compositions exist just as for game play. You get one after you composed a large volume of compositions and regularly fell into the prizes! I did score prizes but produced an insufficient number of recognized compositions so far. Note that sites like chess.com don't count. There is no competition for compositions here where one could score points for a title race. Also I never had any of my compositions registered in the FIDE albums, the primary harvest location for composition crops.

But I'll happily take the honorary master title by public acclaim, Illbtu

No titled chess-composer has EVER invested so much time trying to improve impossible chess-compositions, not to mention composers of such with such vigor and grace like you Master. So the honor is all mine, Maestro!
