Linear formula for w. Bench: 3328507 (#2239) In Stockfish, both the middlegame and endgame bonus for a passed pawn are calculated as a product of two factors. The first is k, chosen based on the presence of defended and unsafe squares. The second is w, a quadratic function of the pawn's rank. Both are only applied if the pawn's relative rank is at least RANK_4. It does not appear that the complexity of a quadratic function is necessary for w. Here, we replace it with a simpler linear one, which performs equally at both STC and LTC. STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 46814 W: 10386 L: 10314 D: 26114 http://tests.stockfishchess.org/tests/view/5d29686e0ebc5925cf0d76a1 LTC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 82372 W: 13845 L: 13823 D: 54704 http://tests.stockfishchess.org/tests/view/5d2980650ebc5925cf0d7bfd Bench: 3328507
