Introduce concept of double pawn protection. Exclude doubly protected by pawns squares when calculating attackers on king ring. Idea of this patch is not to count attackers if they attack only squares that are protected by two pawns. STC LLR: 2.95 (-2.94,2.94) [0.00,5.00] Total: 70040 W: 15476 L: 15002 D: 39562 http://tests.stockfishchess.org/tests/view/5c0354860ebc5902bcee1106 LTC LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 16530 W: 2795 L: 2607 D: 11128 http://tests.stockfishchess.org/tests/view/5c0385080ebc5902bcee14b5 This is third king safety patch in recent times so we probably need retuning of king safety parameters.
