Computer-Generated Chess Problem 03065
What we have here is a 'KQRPPP vs kq' mate in 4 chess puzzle or problem (whichever you wish to call it) composed by the program, Chesthetica, using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is able to generate three-movers, four-moves, five-movers and study-like constructs and also compose problems using specific pieces types fed into it (e.g. composing something original using only a rook vs. five pawns). Read more about it on ChessBase. The largest endgame tablebase in existence today is for 7 pieces (Lomonosov) which contains over 500 trillion positions, most of which have not been seen by human eyes. This problem with 8 pieces goes even beyond that and was therefore composed without any such help.

Humans have been composing original chess problems for over a thousand years. Now a computer can do it too. White is over a rook's worth in material but the precise win in this position still needs to be found. Leave a comment below, if you like. Some of these problems may be trivial for you, especially if you're a club or master player but bear in mind that chess lovers can be found at all levels of play. So do check out some of the other problems. You can probably find something more to your taste.
