Tucson station

Tucson is an Amtrak train depot in Tucson, Arizona, served three times a week by the Sunset Limited and Texas Eagle trains.

History

The depot was built in 1907 by the Southern Pacific Railroad (SP). It was designed by the SP's architect, Daniel J. Patterson, who designed a number of depots during the same era, including the San Antonio Station.

In 1998, the City purchased the entire depot property from the Union Pacific Railroad, which had absorbed the SP. Restoration of the main depot building and the three adjacent buildings, to their 1941 modernized Spanish Colonial Revival architectural style, was completed in 2004. Spanish Colonial Revival elements include the stuccoed brick walls, red clay roof tiles, and colorful, decorative tilework in the waiting room. The station and other railroad buildings are included as contributing resources to the National Register-listed Tucson Warehouse Historic District.

The Old Pueblo Trolley and Sun Link extended their historic streetcar lines to the depot in 2009.

Exchange (chess)

In the tactics and strategy in the board game of chess, an exchange (exchanging) or trade (trading) of chess pieces is series of closely related moves, typically sequential, in which the two players capture each other's pieces. Any types 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 value of piece(s) can be said to be up the exchange or wins the exchange, while the opponent who captures the lower value of piece(s) is down the exchange or loses the exchange. Exchanges occur very frequently in chess, in almost every game and usually multiple times per game. Exchanges are often related to the tactics or strategy in a chess game, but often simply occur over the course of a game.
