Computer-Generated Chess Problem 01831

Published online for the first time, consider this KQB vs kbn chess puzzle or problem (whichever you wish to call it) composed by Chesthetica using the Digital Synaptic Neural Substrate (DSNS) computational creativity approach. It doesn't use endgame tablebases, deep learning or any kind of traditional AI. 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.

The chess problems are published chronologically based on the composition date and time. However, later compositions may have an earlier version of Chesthetica listed because more than one computer (not all running the same version of the program) is used. White is over a rook's worth in material but the precise win in this position still needs to be found. See if you can solve this puzzle within 30 seconds or hit pause and take your time. The solution is provided after that followed by some analysis. If this one is too easy or too difficult for you, try out some of the others. Solving chess puzzles like this can also help improve your game.
