Undefended King Ring 

There was already a penalty for squares only defended by King (undefended) 

This test records a penalty for completely undefended squares in the so called extended king-ring 
(so if we exclude squares defended by a Kg8 for example, we only look at h6 g6 and f6) 

We also exclude squares occupied by opponent pieces in this computation, 
based on the following results
