Instability Operationalized

Ω(t) = [ P(t) · (1 − O(t)) ] / C(t). Real Stockfish NNUE per position. P, O, C are explicit, tunable, and falsifiable. Theoretical claims and philosophical interpretations are flagged separately in methodology notes.

Methodology

P, O, C are weighted composites of measurable board features (king safety, pawn structure, piece coordination, center control, engine eval volatility, multiPV spread, attacked-piece count, phase, clock). Weights are in WEIGHTS for tuning.

Empirical Claims

Ω rises before blunders in many test games. Falsifiable: collapses should correlate with cp loss. Test by running multiple high-blunder games and inspecting Ω curves at fault plies.

Interpretive Notes

OAMChess is not a replacement for Elo. It is an orthogonal regulation metric. Differences indicate style, not strength superiority.
