Also rename some variables in evaluate() while there. passed STC: LLR: 2.94 (-2.94,2.94) <0.00,2.50> Total: 88392 W: 23150 L: 22781 D: 42461 Ptnml(0-2): 318, 9961, 23257, 10354, 306 https://tests.stockfishchess.org/tests/view/61cbbedee68b2a714b6eb110 passed LTC: LLR: 2.93 (-2.94,2.94) <0.50,3.00> Total: 37848 W: 10043 L: 9766 D: 18039 Ptnml(0-2): 26, 3815, 10961, 4100, 22 https://tests.stockfishchess.org/tests/view/61cc0cc3e68b2a714b6ec28c Closes https://github.com/official-stockfish/Stockfish/pull/3875 Follow-up from https://github.com/official-stockfish/Stockfish/commit/a5a89b27c8e3225fb453d603bc4515d32bb351c3 Bench: 4125221
