Introduce midgame initiative This patch finally introduces something that was tried for years: midgame score dependance on complexity of position. More precisely, if the position is very simplified and the complexity measure calculated in the initiative() function is inferior to -50 by an amount d, then we add this value d to the midgame score. One example of play of this patch will be (again!) 4 vs 3 etc same flank endgames where sides have a lot of non-pawn material: 4 vs 3 draw mostly remains the same draw even if we add a lot of equal material to both sides. STC run was stopped after 200k games (and not converging): LLR: -1.75 (-2.94,2.94) [0.50,4.50] Total: 200319 W: 44197 L: 43310 D: 112812 http://tests.stockfishchess.org/tests/view/5d7cfdb10ebc5902d386572c passed LTC: LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 41051 W: 6858 L: 6570 D: 27623 http://tests.stockfishchess.org/tests/view/5d7d14680ebc5902d3866196 This is the first and not really precise version, a lot of other stuff can be tried on top of it (separate complexity for middlegame, some more terms, even simple retuning of values).
