Change trace with NNUE eval support This patch adds some more output to the `eval` command. It adds a board display with estimated piece values (method is remove-piece, evaluate, put-piece), and splits the NNUE evaluation with (psqt,layers) for each bucket for the NNUE net. Example: ``` ./stockfish position fen 3Qb1k1/1r2ppb1/pN1n2q1/Pp1Pp1Pr/4P2p/4BP2/4B1R1/1R5K b - - 11 40 eval Contributing terms for the classical eval: +------------+-------------+-------------+-------------+ | Term | White | Black | Total | | | MG EG | MG EG | MG EG | +------------+-------------+-------------+-------------+ | Material | ---- ---- | ---- ---- | -0.73 -1.55 | | Imbalance | ---- ---- | ---- ---- | -0.21 -0.17 | | Pawns | 0.35 -0.00 | 0.19 -0.26 | 0.16 0.25 | | Knights | 0.04 -0.08 | 0.12 -0.01 | -0.08 -0.07 | | Bishops | -0.34 -0.87 | -0.17 -0.61 | -0.17 -0.26 | | Rooks | 0.12 0.00 | 0.08 0.00 | 0.04 0.00 | | Queens | 0.00 0.00 | -0.27 -0.07 | 0.27 0.07 | | Mobility | 0.84 1.76 | 0.01 0.66 | 0.83 1.10 | |King safety | -0.99 -0.17 | -0.72 -0.10 | -0.27 -0.07 | | Threats | 0.27 0.27 | 0.73 0.86 | -0.46 -0.59 | | Passed | 0.00 0.00 | 0.79 0.82 | -0.79 -0.82 | | Space | 0.61 0.00 | 0.24 0.00 | 0.37 0.00 | | Winnable | ---- ---- | ---- ---- | 0.00 -0.03 | +------------+-------------+-------------+-------------+ | Total | ---- ---- | ---- ---- | -1.03 -2.14 | +------------+-------------+-------------+-------------+ NNUE derived piece values: +-------+-------+-------+-------+-------+-------+-------+-------+ | | | | Q | b | | k | | | | | | +12.4 | -1.62 | | | | +-------+-------+-------+-------+-------+-------+-------+-------+ | | r | | | p | p | b | | | | -3.89 | | | -0.84 | -1.19 | -3.32 | | +-------+-------+-------+-------+-------+-------+-------+-------+ | p | N | | n | | | q | | | -1.81 | +3.71 | | -4.82 | | | -5.04 | | +-------+-------+-------+-------+-------+-------+-------+-------+ | P | p | | P | p | | P | r | | +1.16 | -0.91 | | +0.55 | +0.12 | | +0.50 | -4.02 | +-------+-------+-------+-------+-------+-------+-------+-------+ | | | | | P | | | p | | | | | | +2.33 | | | +1.17 | +-------+-------+-------+-------+-------+-------+-------+-------+ | | | | | B | P | | | | | | | | +4.79 | +1.54 | | | +-------+-------+-------+-------+-------+-------+-------+-------+ | | | | | B | | R | | | | | | | +4.54 | | +6.03 | | +-------+-------+-------+-------+-------+-------+-------+-------+ | | R | | | | | | K | | | +4.81 | | | | | | | +-------+-------+-------+-------+-------+-------+-------+-------+ NNUE network contributions (Black to move) +------------+------------+------------+------------+ | Bucket | Material | Positional | Total | | | (PSQT) | (Layers) | | +------------+------------+------------+------------+ | 0 | + 0.32 | - 1.46 | - 1.13 | | 1 | + 0.25 | - 0.68 | - 0.43 | | 2 | + 0.46 | - 1.72 | - 1.25 | | 3 | + 0.55 | - 1.80 | - 1.25 | | 4 | + 0.48 | - 1.77 | - 1.29 | | 5 | + 0.40 | - 2.00 | - 1.60 | | 6 | + 0.57 | - 2.12 | - 1.54 | <-- this bucket is used | 7 | + 3.38 | - 2.00 | + 1.37 | +------------+------------+------------+------------+ Classical evaluation -1.00 (white side) NNUE evaluation +1.54 (white side) Final evaluation +2.38 (white side) [with scaled NNUE, hybrid, ...] ``` Also renames the export_net() function to save_eval() while there. closes https://github.com/official-stockfish/Stockfish/pull/3562 No functional change
