Renny Bosch: A truly remarkable composition. A simple move count shows Black needs only 17 moves, so he has 13 moves to "waste". How can this possibly be done in a unique way when he has five men to employ? The fact that 13 is an odd number forces the unique 13-move sequence of the black Ra8. Very impressive. (2007-12-22)
