How Geometry Is Fundamental for Chess

- Humans uniquely understand and manipulate geometric concepts like lines, shapes, and transformations, which are fundamental to chess.
- Chess relies on geometric principles, such as discrete lengths (pawns, bishops), rotations (knights, queens), and numerosity (counting squares).
- Animals lack discrete number sense and geometric understanding, as shown by studies with chimpanzees and bonobos struggling with numerical and shape-based tasks.
- Geometric shapes are hypothesized to be processed in the brain via a programming-like language, combining numerosity, rotation, symmetry, and repetition.
- Minimum Description Length (MDL) explains why simpler geometric shapes (e.g., circles) are easier to conceptualize than complex ones (e.g., 17-sided polygons).
- Human ability to decompose and recompose geometric patterns enhances skills like chess, where visualizing and memorizing sequences of moves is crucial.
- Everyday familiarity with geometry masks its complexity and the evolutionary rarity of this cognitive ability.
