Now, here we have a 'KRNP vs kbbnp' chess problem generated autonomously by the prototype computer program, Chesthetica, using the approach known as the DSNS from the sub-field of AI, computational creativity. 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. instructing it to compose something using perhaps a queen vs. three knights). Read more about it on ChessBase. This position contains a total of 9 pieces. The largest endgame tablebase in existence today is for 7 pieces (containing over 500 trillion positions anyway) which means the problem could not have been taken from it regardless.
White to Play and Mate in 4

A seemingly earlier version of Chesthetica on a problem composed later (based on the date and time stamp) simply means that version may have been running on a different computer or operating system user account. White actually has less material than Black yet still wins. The white army is down by about 1 (Shannon) pawn units in value. Try to solve this puzzle. Do try some of the others in the series as well before you go. Solving chess puzzles like this can be good for your health as it keeps your brain active. It may even delay or prevent dementia. Anyway, if standard chess isn't your thing, you might instead like SSCC.
