Compute correction_value before TT lookup Passed single-threaded STC with 128MB hash https://tests.stockfishchess.org/tests/view/6a04a6348d9bd4cd7cd69124 LLR: 2.93 (-2.94,2.94) <0.00,2.00> Total: 103808 W: 26400 L: 26007 D: 51401 Ptnml(0-2): 205, 11212, 28711, 11537, 239 Passed standard SMP STC https://tests.stockfishchess.org/tests/view/6a054f528d9bd4cd7cd69225 LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 80392 W: 20580 L: 20221 D: 39591 Ptnml(0-2): 79, 8872, 21942, 9217, 86 Entering `do_move`, `correction_value` and the TT lookup are always done together, but the TT lookup happens first. Swapping the order allows the execution of `correction_value` to overlap with the in-flight TT prefetch. closes https://github.com/official-stockfish/Stockfish/pull/6822 No functional change
