Computer-Generated Chess Problem 03906
Here is a new 'KQRRNP vs krp' mate in four chess puzzle by the program, Chesthetica, using the approach known as the DSNS from the sub-field of AI, computational creativity. Chesthetica is able to generate mates in two, mates in three, mates in four, mates in five, study-like constructs and also compose problems using specific combinations of pieces fed into it (e.g., composing something original using only a rook vs. five pawns). Read more about it on ChessBase. Any chess position over seven pieces would likely not have been derived from an endgame tablebase which today is limited to seven pieces. Work has only recently begun on one for eight pieces.

Most changes to Chesthetica that result in a slightly higher version number are simply to improve the interface or fix a minor bug, by the way. White is ahead by a queen, a rook and a knight.
