Remove condition for pawn threats It appears as though removing squares that are already attacked by our pawns can be removed. STC LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 51242 W: 11503 L: 11440 D: 28299 http://tests.stockfishchess.org/tests/view/5b58b5a40ebc5902bdb88f52 LTC LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 35246 W: 6063 L: 5966 D: 23217 http://tests.stockfishchess.org/tests/view/5b58f8e20ebc5902bdb8959b How to continue after this patch: there is now a slight semantic overlap between the ThreatByPawnPush and the ThreatBySafePawn bonuses, so hand-tuning either of these, or both at the same time, is natural.
