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.
