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
Horizontal scan rate allowed by the standard was chosen to allow practical TV receiver designs. Compare vertical scan rate (refresh rate), which indicates how often the electron beam is moved from the bottom of the display to the top. Given the horizontal scan rate, the refresh rate can be approximated by dividing the horizontal scan rate by the number of horizontal lines multiplied by 1.05 (since about 5% of the time it takes to scan the screen is spent moving the electron beam back to the top). For instance, a monitor with a horizontal scanning frequency of 96 kHz at a resolution of
