Tweak tropism weight in king danger There was a simplification attempt last week for the tropism term in king danger, which passed STC but failed LTC. This was an indirect sign that maybe the tropism factor was sightly untuned in current master, so we tried to change it from 1/4 to 5/16. STC: LLR: 2.95 (-2.94,2.94) [0.00,4.00] Total: 28098 W: 6264 L: 5990 D: 15844 http://tests.stockfishchess.org/tests/view/5c518db60ebc593af5d4e306 LTC: LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 103709 W: 17387 L: 16923 D: 69399 http://tests.stockfishchess.org/tests/view/5c52a5510ebc592fc7baea8b Bench: 4016000
