Result of 32k games of tuning at 60+0.6 8-thread. Link to the tuning attempt: https://tests.stockfishchess.org/tests/view/65def7b04b19edc854ebdec8 Passed VVLTC first SPRT: https://tests.stockfishchess.org/tests/view/65e51b53416ecd92c162ab7f LLR: 2.94 (-2.94,2.94) <0.00,2.00> Total: 37570 W: 9613 L: 9342 D: 18615 Ptnml(0-2): 2, 3454, 11601, 3727, 1 Passed VVLTC second SPRT: https://tests.stockfishchess.org/tests/view/65e87d1c0ec64f0526c3eb39 LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 123158 W: 31463 L: 31006 D: 60689 Ptnml(0-2): 5, 11589, 37935, 12044, 6 Note: The small net and psqt-only thresholds have been moved to evaluate.h. The reasoning is that these values are used in both `evaluate.cpp` and `evaluate_nnue.cpp`, and thus unifying their usage avoids inconsistencies during testing, where one occurrence is changed without the other (this happened during the search tune SPRT). closes https://github.com/official-stockfish/Stockfish/pull/5101 Bench: 1741218
