Take a look at this 'KQB vs kbnp' four-move chess problem generated by the program, Chesthetica, using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is capable of composing positions that may otherwise take centuries or longer to arise in an actual game; so you can enjoy them right now instead. There is also no proven limit to the quantity or type of legal compositions that can be automatically generated.
