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.
However, this doesn't mean that all of the players are playing together on the same board (which would be known as a consultation match), but rather that the results of all games played by the team are added together to determine the overall match result. Team chess brings a new dynamic to chess competition.
