Take a look at this 'KQRRP vs krpp' mate in 4 chess construct composed autonomously by Chesthetica using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is able to generate mates in 3, mates in 4, mates in 5, study-like constructs and also compose problems using specific combinations of pieces fed into it (such as using only a queen vs. rook and knight). Read more about it on ChessBase.
If you notice an earlier version of Chesthetica listed with a newer problem, that simply means an earlier version may have been running on a different computer or OS user account. White has a decisive material advantage in this position but the winning sequence may not be immediately clear. Leave a comment below, if you like. Collectively, these puzzles are intended to cater to players of all levels.
