Simplify KingProtector penalty. Recent tuning results implied this penalty is more important for knights and bishops, and almost negligible for rooks and queen. Passed as simplification both STC LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 20873 W: 4592 L: 4469 D: 11812 http://tests.stockfishchess.org/tests/view/5b2fb4d00ebc5902b2e57e84 and LTC LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 46069 W: 7949 L: 7870 D: 30250 http://tests.stockfishchess.org/tests/view/5b2fcc4b0ebc5902b2e580c5 Closes https://github.com/official-stockfish/Stockfish/pull/1660 Bench: 5487679
