· 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
Removing twenty-three verified ineffective checks, clamps, resets, and settings along with the dead manual evaluation, including tapered evaluation and its endgame column, simplifies the architecture without reducing playing strength. Piece evaluation with its middlegame column, passed pawns including their hash budget share, network format, weights, tunable parameters, and UCI Universal Chess Interface, the text protocol between a chess engine and the program that runs it. options are preserved.

Stages
| Field | short stage | long stage |
|---|---|---|
| Verdict | passed | passed |
| 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. | +1.53 ± 1.88 | +1.00 ± 1.60 |
| nElo Normalised Elo: relates the mean score excess of a colour-swapped pair to the spread of the pair results. | +3.64 ± 4.47 | +2.44 ± 3.91 |
| Games | 23,190 | 30,260 |
| Wins / draws / losses | 5,359 / 12,574 / 5,257 | 6,772 / 16,803 / 6,685 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 23 / 1906 / 7626 / 2026 / 14 | 3 / 2484 / 10071 / 2567 / 5 |
| 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 | +2.96 |
| Bounds | −2.94 … +2.94 | −2.94 … +2.94 |
| 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. | [-3.0, 0.0] | [-3.0, 0.0] |
| Error rates α / β | 0.05 / 0.05 | 0.05 / 0.05 |
| Model | normalized | normalized |
| time control Base time plus increment per move in seconds, e.g. 8+0.08: eight seconds per game plus 0.08 seconds per move. | 8+0.08 | 40+0.4 |
