Retuned values after eval quantize patch. The last search tune patch was tested before the implementation of #2733 which presumably changed the search characteristics noticeably. Another tuning run was done, see https://tests.stockfishchess.org/tests/view/5ee5b434ca6c451633a9a08c and the updated values passed these tests: STC: LLR: 2.93 (-2.94,2.94) {-0.50,1.50} Total: 34352 W: 6600 L: 6360 D: 21392 Ptnml(0-2): 581, 3947, 7914, 4119, 615 https://tests.stockfishchess.org/tests/view/5ee62f05ca6c451633a9a15f LTC 60+0.6 th 1 : LLR: 2.97 (-2.94,2.94) {0.25,1.75} Total: 11176 W: 1499 L: 1304 D: 8373 Ptnml(0-2): 69, 933, 3403, 1100, 83 https://tests.stockfishchess.org/tests/view/5ee6205bca6c451633a9a147 SMP LTC 20+0.2 th 8 : LLR: 2.93 (-2.94,2.94) {0.25,1.75} Total: 54032 W: 6126 L: 5826 D: 42080 Ptnml(0-2): 278, 4454, 17280, 4698, 306 https://tests.stockfishchess.org/tests/view/5ee62f25ca6c451633a9a162 Closes https://github.com/official-stockfish/Stockfish/pull/2742 Bench 4957812
