Eval points are likely not accurate for a single position. They are intended to be used on positions 3-4 full moves down a minimax tree, with the current position matching that of the forceably best position.
Even so, P1 N3 B3 R5 Q9 values are very inaccurate near checkmate too. I see no harm in knowing some point values for files and other sqyares or pins.
LCO and Stockfish have public source code. I just have to find the easiest to understand source of it.
Since AlphaZero looks at much fewer positions per second than Stockfish, each one is more accurate and more complex.
Lev Alburt authored "Building Up Your Chess." The book teaches how to evaluate positions and give point values. Sounds good, but dated 2002. Are there any more modern books based on the evaluation of Stockfish, LCO, or AlphaZero?
Positional books tell us which structures are good, but they don't say how many centipawns they are worth.
I do know that center pawns are worth 30% more than flank pawns until most of the pieces are traded off, when it reverses. And that pawns slightly gain value as they go down the board, but don't gain lots unless they are on the 7th or connected. And double pawns are worth about half a pawn each. Thats the kind of info I want, but also for controlling open files, squares near the enemy king, bad bishop vs good. I know a knight anchored on the 6th rank is worth 5 points, 5.5 or more if near the king. Knights can be wirth 2 points in some open end games, or 4 paired with a queen.
