Computer-Generated Chess Problem 02843
A new if not unique KQNP vs kbn mate in 4 chess puzzle created by the program, Chesthetica, using the computational creativity approach which doesn't use any kind of traditional AI or even deep learning. Chesthetica has the creative ability to compose positions on an 8x8 canvas that may otherwise take centuries to arise in an actual game, if ever. 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.

Some of the earliest chess problems by humans are over 10 centuries old but original ones by computer are very recent. White is over a rook's worth in material but the precise win in this position still needs to be found. Why not time yourself how long it took you to solve this? Collectively, these puzzles are intended to cater to players of all levels.
