BRAZILIAN_DRAUGHTS_RULESconstant
Brazilian draughts: the international rules of capture and crowning on 8×8, with twelve men, and the draws of the Brazilian confederation's own rules (CBJD, Regras Oficiais) rather than the FMJD's 8×8 set, which differs. A third repetition (art. 98), and five moves each for the small endings of art. 99: two kings against two, two kings against one, two kings against a king and a man, a king against a king, a king against a king and a man. Its twenty-move kings-only count is in rules/noProgress.ts.
NOT APPLIED: art. 100, five moves for three pieces against a lone king on the long diagonal, for the same reason as the FMJD's version of it above. With it left out, those endings are bounded by the kings-only count instead.

| Name | Type | Description |
|---|---|---|
menRows | number | Rows of men each side starts with, on the dark squares of its own side of the board. |
menCaptureBackward | boolean | Whether a man may capture backward as well as forward. It always steps forward only. |
flyingKings | boolean | Whether a king flies: moves any distance along an open diagonal, and takes a piece at any distance, landing on any empty square beyond it. Otherwise a king moves one square and jumps an adjacent piece, as a man does, both ways. |
captureChoice | CaptureChoice | |
crownMidCapture | CrownMidCapture | |
