New Imbalance Tables Tweak Imbalance tables tweaked to contain MiddleGame and Endgame values, instead of a single value. The idea started from Fisherman, which requested my help to tune the values back in June/July, so I tuned the values back then, and we were able to accomplish good results, but not enough to pass both STC and LTC tests. So after the recent changes, I decided to give it another shot, and I am glad that it was a successful attempt. A special thanks goes also to mstembera, which notified me a simple way to let the patch perform a little better. Passed STC: LLR: 2.94 (-2.94,2.94) {-0.25,1.25} Total: 115976 W: 23124 L: 22695 D: 70157 Ptnml(0-2): 2074, 13652, 26285, 13725, 2252 https://tests.stockfishchess.org/tests/view/5fc92d2d42a050a89f02ccc8 Passed LTC: LLR: 2.94 (-2.94,2.94) {0.25,1.25} Total: 156304 W: 20617 L: 20024 D: 115663 Ptnml(0-2): 1138, 14647, 46084, 15050, 1233 https://tests.stockfishchess.org/tests/view/5fc9fee142a050a89f02cd3e closes https://github.com/official-stockfish/Stockfish/pull/3255 Bench: 4278746
