Run T-0233 rejected

2026-11-06 · Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds or the game limit fixed in advance; then the test stops.

Hypothesis

Combining persistent pin accounting in the evasion term, verification of negative capture SEE Static exchange evaluation: an estimate of the material outcome of a capture sequence on one square, without searching. pruning via the legal exchange sequence, null-move reduction limits when friendly pieces hang, exempting history-supported killer and countermoves from quiet SEE pruning, and multi-cut on the exclusion value from beta increases playing strength.

Stages

Point estimate with the reported 95-percent half-width, per stage. The dashed line is zero. Estimates from a stopped sequential test are biased by the stopping rule; the interval is nominal.

Elo Strength difference to the opponent, estimated from the games, with a 95-percent half-width where the oracle reported one. Never an absolute rating.	−5.14 ± 4.52
nElo Normalised Elo: relates the mean score excess of a colour-swapped pair to the spread of the pair results.	−10.39 ± 9.14

pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points.	`7 / 690 / 1463 / 604 / 9`
LLR Log-likelihood ratio, the running evidence of an SPRT. It starts at 0; a stage passes at the upper bound and fails at the lower one.	−2.96
