Year Of Death Missing
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A player must get out of check if possible by moving the king to an unattacked square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot remove the check by any of these options, or if using any of these options would result in the player being in check by another piece, the game ends in checkmate and the player loses. Players cannot make any move that puts their own king in check.

Exchange (chess)
In chess, an exchange or trade of chess pieces is a series of closely related moves, typically sequential, in which the two players each other's pieces. Any type of pieces except the kings may possibly be exchanged, i.e. captured in an exchange, although a king can capture an opponent's piece. Either the player of the white or the black pieces may make the first capture of the other player's piece in an exchange, followed by the other player capturing a piece of the first player, often referred to as a ''recapture''. Commonly, the word "exchange" is used when the pieces exchanged are of the same type or of about equal value, which is an ''even exchange''. According to chess tactics, a bishop and a knight are usually of about equal value. If the values of the pieces exchanged are not equal, then the player who captures the higher-valued piece can be said to be ''up the exchange'' or ''wins the exchange'', while the opponent who captures the lower-valued piece is ''down the ex ...

Knights capture in the same way, replacing the enemy piece on the square and removing it from the board. A knight can have up to eight available moves at once. Knights and pawns are the only pieces that can be moved in the chess starting position. Val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
