Cross Chess in Cross Chess from Gliński's and Shafran's hexagonal variants, resulting in move possibilities more akin to standard chess. (E.g., a bishop has six diagonal move directions in Glinski's hex chess, whereas a Cross Chess bishop has four directions; a rook has six directions in Glinski's, whereas along ranks and on the Cross Chess board, it has four.) As with hex-based boards, three cell colors are used, but same-color cells highlight horizontal ranks on the Cross Chess board, not diagonals. The diagram shows the starting setup. Special rank and diagonal paths determine how pieces move, as described below. Check, checkmate, and
Vertical–horizontal illusion Vertical–horizontal illusion The vertical–horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. This involves a bisecting component that causes the bisecting line to appear longer than the line that is bisected. People often overestimate or underestimate the length of the bisecting line relative to the bisected line of the same length. This even happens if people are aware that the lines are of the same length. Cross-cultural differences in susceptibility to the vertical–horizontal illusion have been noted. People from Western cultures and people living in
