Combination (chess)

In chess, a combination is a sequence of moves, often initiated by a sacrifice, which leaves the opponent few options and results in tangible gain. At most points in a chess game, each player has several reasonable options from which to choose, which makes it difficult to plan ahead except in strategic terms. Combinations, in contrast to the norm, are sufficiently forcing that one can calculate exactly how advantage will be achieved against any defense. Indeed, it is usually necessary to see several moves ahead in exact detail before launching a combination, or else the initial sacrifice would not be undertaken.

Definition

In 1952/53, the editors of Shakhmaty v SSSR decided on this definition: A combination is a forced sequence of moves which uses tactical means and exploits specific peculiarities of the position to achieve a certain goal. (Golombek 1977)

Irving Chernev said:

Example

A combination is usually built out of more fundamental chess tactics such as forks, pins, skewers, undermining, discovered attacks, etc. Thus a combination must be at least three moves long, but the longer it takes to recoup the initial sacrifice, the more impressive the combination. The position below from a game between G. Stepanov and Peter Romanovsky begins a combination which illustrates several forks and skewers.

Combination (disambiguation)

A combination is a mathematical collection of things in a context where their specific order is irrelevant.

Hollowell-Dhar also released materials starting 2014, under the name of KSHMR.

Biography

Early days

The duo met in their sophomore year while attending Berkeley High School. Singer-Vine was featured in a rap CD that was being passed around campus. When Dhar eventually heard the CD, he subsequently created a response. However, the “diss” response brought the two together and they soon became friends. In 2003, the two joined together to create what is now The Cataracs (named after the phrase “Who smoke ‘til your eyes get cataracts” from Snoop Dogg's song “What's my name Pt. 2”). In the summer of 2006, they released their first album, Technohop Vol. 1. In August 2006, the group joined with The Pack to make the single “Blueberry Afghani”. The song soon became a hit and was chosen as a “Download of the Week” by 106 KMEL and many music sites such as The Fader, UK’s Hip Hop Connection and XLR8R praised it.

Sunrise (Sacramento RT)

Sunrise is a side-platformed Sacramento RT light rail station in Rancho Cordova, California, United States. The station was opened on June 11, 2004, and is operated by the Sacramento Regional Transit District. As part of the Gold Line, it has service to Downtown Sacramento, California State University, Sacramento, Gold River and Folsom. The station is located on Folsom Boulevard just south of Highway 50 at the intersection of Sunrise Boulevard.

Sunrise, along with Zinfandel and Cordova Town Center, opened on June 11, 2004, as part of an $89 million, 2.8-mile (4.5 km) extension of the Gold Line east of the Mather Field/Mills station. Sunrise served as the eastern terminus for the Gold Line until the extension to Historic Folsom opened on October 15, 2005. Rancho Cordova city officials have stated the establishment of the stations will help in the development of transit-oriented development/redevelopment of the Folsom corridor through the city.

Sunrise serves as a major station on the eastern section of the Gold Line. Light rail operates from this stop to downtown at 15-minute intervals during peak time periods, while trains leave Folsom at 30-minute headways during this portion of the day. Many trains end their routes at this facility, as service between Folsom and Sunrise ceases as 7:30 p.m. every evening. Additionally, connection to RT Bus Route 74 can be made, and there is a 487-space park and ride lot located at the station.
