Computer-Generated Chess Problem 03943

Here is a new 'KQR vs knnpppp' four-move chess problem generated autonomously by a computer using the fairly new computational creativity approach known as the DSNS (Digital Synaptic Neural Substrate). 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.

Most changes to Chesthetica that result in a slightly higher version number are simply to improve the interface or fix a minor bug, by the way. White has a rook and a queen for Black's four pawns and two knights. Do share and try out some of the others too. Solving chess puzzles like this can also help improve your game.
