 I wouldn't like to be black in that game, he played absolutely appallingly !

I like this . Good stuff. But why not create a herd of knights and let them feed on the land for 48 moves or so?

 LOL... but what about a couple of bishops instead of rooks?

Hahahaha!! You have imagination! FIve knights would be more fun!
