Computer-Generated Chess Problem 03187

What we have here is a 'KQNNPPP vs kqrrn' mate in 3 chess problem generated autonomously by Chesthetica using the fairly new computational creativity approach called the 'DSNS'. Chesthetica is able to generate three-movers, four-moves, five-movers and study-like constructs and also compose problems using specific pieces types fed into it (such as using only a queen vs. rook and knight). Read more about it on ChessBase. The largest endgame tablebase in existence today is for 7 pieces (Lomonosov) which contains over 500 trillion positions, most of which have not and never will be seen by human eyes. This problem with 12 pieces goes even beyond that and was therefore composed without any such help whatsoever.
