Native examples were selected after counting from 15215 sampled White-quiet boards, including targeted starting-rank and losing candidates. Statistics still cover every enumerated position. An absent example does not prove the category is absent.
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 18, Black 4.
