This is the fourth special example file for the 25th TT CCM C 5.5.2009.

In the previous file we have seen ser-h=17 by Gaspar J. Perrone. It used multiple black kings under Rex Multiplex conditions. However there are many less fairy examples with similar idea of unpinning and repinning the pieces on various lines aimed at bK. Some of the seven problems quoted below aim at multiple promotions, some at the strategy.
