Computer-Generated Chess Problem 03023

Consider this 'KRNPP vs krrp' five-move chess construct composed autonomously by a computer using the DSNS computational creativity approach which doesn't use any kind of traditional AI. Chesthetica has the creative ability to compose positions 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. Any chess position with this many pieces could not possibly have been obtained from known endgame databases. Chesthetica is therefore the real McCoy.

Even with the same version number, each copy of Chesthetica 'evolves' and performs somewhat differently over time. It looks like the solution might involve a pawn promotion. Do share and try out some of the others too. Solving chess puzzles like this can also help improve your game.
