Recent question:

How are the scores decided in Chess?

It has been argued that PV scores for Stockfish (the engine being used by chess.com) can be interpreted as something like:

+1.0 is a pawn advantage for White. -0.5 is a half-pawn advantage for Black.

Is that correct? The weights and parameters in Stockfish are either manually calibrated or tuned by something like the SPSA optimiser.

The objective function is to maximise the playing strength. Maximising playing strength has nothing to do with making sure "+1.0 is a pawn advantage for White". In fact, we should be able to scale all all the PV scores by a constant. As long as the engine makes the same move, the magnitude of the scores shouldn't matter.

This is consistent to the minimax algorithm, where both players only care how to minimize/maximise the evaluation. Again, there is no efforts to make the PV scores human-interpretable.

To me, the PV scores are only important relatively, not absolutely. For instance, we should be able to say "+2.0 is about two-times advantage for White than a position with +1.0 for White.", but that shouldn't have anything to do with pawns. Similarly, if I modify the source code and scale the outputs by a factor of 10. I can still say: "+20.0 is about two-times advantage for White than a position with +10.0 for White". We shouldn't be able to connect the scores to pawns, knights, bishops etc.

Should I call all answers in the question technically incorrect?
