Computer-Generated Chess Problem 04027
Here is a new 'KQRBP vs kqrb' mate in four chess construct composed autonomously by the program, Chesthetica, using the approach known as the DSNS from the sub-field of AI, computational creativity. Chesthetica is able to generate mates in two, mates in three, mates in four, mates in five, study-like constructs and also compose problems using specific combinations of pieces fed into it (e.g., composing something original using only a rook vs. five pawns). Read more about it on ChessBase. The largest complete (Lomonosov) tablebase today is for seven pieces which contains over 500 trillion positions. With each additional piece, the number of possible positions increases exponentially. It is therefore unlikely that this problem with nine pieces could have been taken from such a database.

Even with the same version number, each copy of Chesthetica 'evolves' and may perform somewhat differently over time. Chesthetica composes everything autonomously (no human intervention) and even chooses the main line of the solution to show you. If this one is too easy or too difficult for you, try out some of the others. Feel free to copy the position into a chess engine and potentially discover even more variations.
