Introduce king flank defenders This patch implements what we have been trying for quite some time - dependance of kingdanger on balance of attackers and defenders of king flank, to avoid overestimate attacking power if the opponent has enough defenders of king position. We already have some form of it in bishop and knight defenders - this is further work in this direction. What to do based on this? 1) constant 4 is arbitrary, maybe it is not optimal 2) maybe we can use quadratic formula as in kingflankattack 3) simplification into alrealy existing terms is always a possibility :) 4) overall kingdanger tuning always can be done. passed STC: http://tests.stockfishchess.org/tests/view/5dcf40560ebc590256325f30 LLR: 2.96 (-2.94,2.94) [-1.50,4.50] Total: 26298 W: 5819 L: 5632 D: 14847 passed LTC: http://tests.stockfishchess.org/tests/view/5dcfa5760ebc590256326464 LLR: 2.96 (-2.94,2.94) [0.00,3.50] Total: 30600 W: 5042 L: 4784 D: 20774 Closes https://github.com/official-stockfish/Stockfish/pull/2415 Bench: 4496847
