Computer-Generated Chess Problem 02560

Now, here we have a 'KRNP vs kqr' mate in 3 chess puzzle created by a computer program, Chesthetica, using the approach known as the DSNS from the sub-field of AI, computational creativity. Depending on the type and complexity of the problem desired, a single instance of Chesthetica running on a desktop computer can probably generate anywhere between one and ten problems per hour.

Chesthetica, especially if running on multiple computers or operating system user accounts, is capable of generating far too many compositions than can be published in a timely fashion here. The newer ones will therefore only be published some time later. This is why the composition date above does not match today's date. It looks like the solution might involve a pawn promotion. Why not time yourself how long it took you to solve this? Collectively, these puzzles are intended to cater to players of all levels.
