Computer-Generated Chess Problem 02437

This is an original 'KQR vs krn' mate in 3 chess problem generated by Chesthetica using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is able to generate mates in 3, mates in 4, mates in 5, study-like constructs and also compose problems using specific combinations of pieces fed into it (such as using only a queen vs. rook and knight).

White is over a rook's worth in material but the precise win in this position still needs to be found. Leave a comment below, if you like. Some of these problems may be trivial for you, especially if you're a club or master player but bear in mind that chess lovers can be found at all levels of play. So do check out some of the other problems. You can probably find something more to your taste.
