Fix doubled pawns asymmetry When evaluating double pawns we use always lsb() to extract the frontmost square. This breaks evaluation color symmetry as is possible to verify with an instrumented evaluate() Value evaluate(const Position& pos) { Value v = do_evaluate<false>(pos); Position p = pos; p.flip(); assert(v == do_evaluate<false>(p)); return v; } Passed no regression test: STC LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 21035 W: 4244 L: 4122 D: 12669 LTC LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 39839 W: 6662 L: 6572 D: 26605 bench: 8255966
