办公室地板成了棋盘，座椅互相对弈

Frame: a wide 16:9 composition. The whole decisive central board, both workers and the moved chairs sit fully inside the picture with breathing room, and the office architecture continues out to every edge. Walls, chair backs and floor are plain: no writing, logos or numbers. Neutral window light picks out the chair silhouettes, the alternating square boundaries, the hands on chair backs and the wheeled floor contacts. Scene: a conceptual interior photograph from a high three-quarter angle, set in an open office whose entire floor is one large chessboard grid of alternating cream and charcoal squares. In place of chess pieces, ergonomic wheeled office chairs stand on the squares as two opposing teams, pale upholstered chairs against dark upholstered ones. Tall executive chairs hold the commanding positions, smaller task chairs fill the ranks, and each chair is centered on a single square. The grid belongs to the room's floor; it is not a portable board on a desk. Action: along the near edge of the grid, a suited worker rolls a pale chair carefully forward onto a central square, hands on its back, every caster on that square. On the far side, a second suited worker steers a dark chair toward an opposing square, hands on its back. They face each other across the contested central ranks, while the chairs around them already form clear rival lines. Their deliberate moves let a hostile office game read at once, without a caption.
