Use a fraction of king danger in endgame score When SF has an attack on the opponent king in one flank, the huge midgame -> endgame gradient of the tapered eval prevents us to properly evaluate neutral exchanges on the other flank as the current king danger score is a pure midgame term. This may affect SF's ability to switch to defense in some positions. We add a small contribution of the king danger to the endgame score to limit this effect. Again suggested in the following forum thread: https://groups.google.com/forum/?fromgroups=#!topic/fishcooking/xrUCQ7b0ObE Passed STC: LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 12719 W: 2371 L: 2192 D: 8156 http://tests.stockfishchess.org/tests/view/5919761a0ebc59035df3468f And LTC: LLR: 2.95 (-2.94,2.94) [0.00,5.00] Total: 31293 W: 4194 L: 3974 D: 23125 http://tests.stockfishchess.org/tests/view/591980450ebc59035df34695 Bench: 5961548 Closes #1118
