The pressure is estimated by means of a mercury or an aneroid manometer. A stethoscope is normally used in conjunction with the instrument to listen to the blood pressure sounds (a stethoscope is not needed with an electronic sphygmomanometer).
ObjectID: 171. Description Edit | History. Chess is a two-player, abstract strategy board game that represents medieval warfare on an 8x8 board with alternating light and dark squares. Opposing pieces, traditionally designated White and Black, are initially lined up on either side.
A lot of other games played on a board require strategy as well, but I donât see people debating whether or not Battleship, Monopoly or Life should be considered a sport. Checkers, the closest equivalent to chess, doesnât get nearly the amount of attention in debate over what is considered a sport.
