Run T-0188 interrupted
Wall run: the full number of games was played without the SPRT reaching a verdict. Interrupted, no verdict; it counts neither as passed nor in the share of verdicts.
· Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops.
Hypothesis
Ordering the suffix moves following the best move after each completed root iteration for the next depth (from depth 2 onward) using the updated move picker logic, rather than sorting by prior-iteration node counts and a dedicated root history table, increases the engine's playing strength under time controls. The best move itself at the front and all search, reduction, and time management rules remain unchanged.

Stages
| Field | short stage | long stage |
|---|---|---|
| Verdict | passed | interrupted |
| 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. | +3.17 ± 2.50 | +0.68 ± 1.52 |
| nElo Normalised Elo: the Elo difference divided by the spread of the game results, so that the SPRT bounds mean the same at different time controls. | +6.34 ± 5.00 | +1.39 ± 3.11 |
| Games | 18,532 | 48,000 |
| Wins / draws / losses | 4,309 / 10,083 / 4,140 | 10,785 / 26,524 / 10,691 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 21 / 2132 / 4805 / 2273 / 35 | 17 / 5623 / 12635 / 5699 / 26 |
| 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. | +2.95 | −2.21 |
| 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; then the test stops. | [0.0, 5.0] | [0.0, 5.0] |
| 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 |
