Counts combine both sides to move, including captures. Win and loss are relative to the side to move. Unknown results are unresolved, not draws.
All positionsThe side to move has no capture. Percentages use this table's legal-position total; counts include both sides to move.
Win: 34.099.744.454 (7.2%)Neither side has a capture. Percentages use this table's legal-position total; counts include both sides to move.
Win: 15.865.635.612 (5.7%)Capture-filtered totals are exhaustive across saved and mirrored slices. Read blocks have their checksums checked; WDL correctness is not independently verified.
Saved slices: 856; mirrored slices: 785. Invalid or unreadable files excluded: 0. Counts cover saved and color-reversed mirrored slices; examples sample saved slices. Header and file length checked; payload checksum and WDL correctness are not verified by this report.
Example search: sampled. Examined 983556 of 966202999441 saved physical-board indexes (815941 legal, 527012 double quiet). Large reports inspect at most 1000000 indexes in evenly spaced windows across saved slices. An absent example does not prove that the category is absent.
Only exact partial WIN/DRAW/LOSS values qualify as example results. Bounds and unknown alternatives remain distinct. DPART002 blocks used for examples have their block checksums checked; full-file checksums and independent WDL correctness are not verified.
One example per category. Every starting position is double quiet: neither side has a capture. Results and move outcomes are relative to the player to move in the diagram. Kings have a double ring.
White-to-move examples are preferred; Black-to-move examples are retained when no qualifying White-to-move example was found.
Pip count means remaining rank distance to promotion (kings: zero). Highest pip count puts men nearest their starting ranks; both sides must simultaneously attain their material's maximum. Material disadvantage means fewer pieces.
At least three legal moves; exactly one wins and every alternative draws or loses.
White to move: Win. Pip count: White 35, Black 35.

Some dependency probes were unavailable or exceeded the memory budget. Unknown alternatives were not treated as draws; categories without an example may be incomplete.
The Black-starting-rank category additionally inspected 20000 candidate boards, working outward from White's starting rank, with a limit of 20000. It shows the closest proven winner found; unavailable results remain unresolved.
