Computer-Generated Chess Problem 02723

Here is a new 'KQRB vs kqrrp' chess construct composed autonomously by a computer program, Chesthetica, using the Digital Synaptic Neural Substrate AI computational creativity method. Depending on the type and complexity of the problem desired, a single instance of Chesthetica running on a desktop computer can probably generate anywhere between one and ten problems per hour. Any chess position with this many pieces could not possibly have been obtained from known endgame databases. Chesthetica is therefore the real McCoy.

Most changes to Chesthetica that result in a slightly higher 'version number' are simply to improve the interface, by the way. White actually has less material than Black. The white army is down by about 3 (Shannon) pawn units in value. Try to solve this as quickly as you can. If you like it, please share with others.
