Computer-Generated Chess Problem 03355
Here is a new 'KRRBBN vs kbpp' mate in 5 chess puzzle or problem (whichever you wish to call it) composed 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 2, 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., instructing it to compose something using perhaps two queens vs. four rooks). Read more about it on ChessBase. This position contains a total of 10 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. If this one is too easy or too difficult for you, try out some of the others. Feel free to copy the position into a chess engine and discover even more variations of the solution.
