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 Was yellow at STC LLR: -2.97 (-2.94,2.94) [0.00,5.00] Total: 112499 W: 20649 L: 20293 D: 71557 and passed LTC LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 36805 W: 5100 L: 4857 D: 26848 Bench: 8430233 Resolves: #619
