· Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops.
Hypothesis
Removing the check exception from both the delta pruning and SEE Static exchange evaluation: an estimate of the material outcome of a capture sequence on one square, without searching. delta pruning conditions in quiescence search, so that checking captures are also pruned by them, is expected to increase playing strength in timed games against the baseline. Mate bounds, recapture exceptions, and protections when in check or on promotions are retained, and checking moves remain exempt from the move limit and exchange threshold.

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. | +3.37 ± 2.62 | +5.79 ± 3.82 |
| 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. | +6.78 ± 5.27 | +11.73 ± 7.74 |
| Games | 16,682 | 7,742 |
| Wins / draws / losses | 3,856 / 9,132 / 3,694 | 1,821 / 4,229 / 1,692 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 16 / 1902 / 4363 / 2024 / 36 | 2 / 869 / 2003 / 992 / 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; 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 |
