Computer-Generated Chess Problem 03233

Here is a 'KQRBN vs kqrrpp' four-move chess problem generated by the prototype computer program, Chesthetica, using the fairly new computational creativity approach called the 'DSNS'. There is also no proven limit to the quantity or type of legal compositions that can be automatically generated.

Chesthetica, especially if running on multiple computers or operating system user accounts, is capable of generating far too many compositions than can be published in a timely fashion here. The newer ones will therefore only be published some time later. This is why the composition date above does not match today's date. White actually has less material than Black yet still wins. The white army is down by about 1 (Shannon) pawn units in value. 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.
