Computer-Generated Chess Problem 02934
Now, this is a 'KQRN vs krbbp' chess problem generated autonomously by the program, Chesthetica, using the 'DSNS' computational creativity approach which does not use any kind of machine or deep learning. 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 (e.g. to compose something using a rook, bishop, knight and three pawns vs. a queen and a rook). 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.

If you notice any version of Chesthetica 'skipped' from one problem to the next, that simply means additional (minor) changes were made to the program before it was set to run again. Get a glimpse into the 'mind' of a computer composer. Leave a comment below, if you like. Take some time to study the analysis and you might appreciate the puzzle a little more.
