Curated board states across the arc of a game. Pick a variant, then select a position to boot a new match.
The nine-pawn arc opens; f-file gleams with intent.
A pawn offered; bishops sight the long diagonals.
One bishop, one pawn, one long line to the horizon.
Both knights spring; the arc bends around them.
Queens are gone; rooks stalk the open f-file.
A rook shepherds a passed pawn to the horizon.
