In chess chess endgame, endgames with a bishop (chess), bishop, a pawn (chess), pawn that is a may be the wrong rook pawn. With a single bishop, the result of a position may depend on whether or not the bishop controls the square on the chessboard on which the pawn would promotion (chess), promote. Since a side's rook pawns promote on opposite-colored squares, one of them may be the "wrong rook pawn". This situation is also known as having the ''wrong-colored bishop'' or ''wrong bishop'', i.e. the bishop is on the wrong colored squares in relation to the rook pawn. In many cases, the wrong rook pawn will only draw (chess), draw, when any other pawn would win.

Draw By Agreement
A game of chess can end in a draw by agreement. A player may offer a draw at any stage of a game; if the opponent accepts, the game is a draw. In some competitions, draws by agreement are restricted; for example draw offers may be subject to the discretion of the arbiter, or may be forbidden before move 30, or even forbidden altogether. The majority of draws in chess are by agreement. Under FIDE rules, a draw should be offered after making the move and before pressing the game clock, then marked in the scoresheet as ''(=)''. However, draw offers made at any time are valid. If a player offers a draw before making a move, the opponent has the option of requesting a move before deciding whether or not to accept the offer. Once made, a draw offer cannot be retracted and is valid until rejected. A player may offer a draw by asking, "Would you like a draw?", or similar; the French word ''remis'' (literally "reset") is internationally understood as a draw offer and may be used if the pl ...

The 1985 World Chess Championship was played between Anatoly Karpov and Garry Kasparov in Moscow from September 3 to November 9, 1985. Kasparov won, to become the thirteenth and youngest world champion at the age of 22. Background It is difficult to view the 1985 World Chess Championship in isolation, following as it did only 7 months after the highly controversial finish of the 1984 championship between the same players. On 8 February 1985, after 48 games had been contested over 5 months, the 1984 championship was abandoned with no result, becoming the first, and thus far only, chess world championship to finish in this way. Politics gave another angle to the Kasparov–Karpov encounters. Due to the changing political climate in Russia at the time, the matches were often depicted as a clash of ideologies, between "new Russia" represented by Kasparov and Mikhail Gorbachev and "old Russia" represented by Karpov and Communists such as Leonid Brezhnev.

Opposite-colored Bishop Endgame
The opposite-colored bishops endgame is a chess endgame in which each side has a single bishop and the bishops reside on opposite-colored squares. Without other besides pawns, these endings are widely known for their tendency to result in a draw. These are the most difficult endings in which to convert a small advantage to a win. With additional pieces, the stronger side has more chances to win, but not as many as when bishops are on the same color. Many players in a poor position have escaped a loss by trading down to such an endgame. These endgames are sometimes drawn when one side has an advantage of two or even three pawns, since the weaker side can create a blockade on the squares on which their bishop operates. General principles Edmar Mednis gives two principles for endgames with bishops on opposite colors: # If a player is down he should look for drawing chances in an endgame with only the bishops and pawns. # With (queen or rook) on the board, having bishops on ...

Zugzwang
Zugzwang (German for "compulsion to move", ) is a situation found in chess and other turn-based games wherein one player is put at a disadvantage because of their obligation to make a move; a player is said to be "in zugzwang" when any legal move will worsen their position. Although the term is used less precisely in games such as chess, it is used specifically in combinatorial game theory to denote a move that directly changes the outcome of the game from a win to a loss. Putting the opponent in zugzwang is a common way to help the superior side win a game, and in some cases it is necessary in order to make the win possible. The term ''zugzwang'' was used in German chess literature in 1858 or earlier, and the first known use of the term in English was by World Champion Emanuel Lasker in 1905. The concept of zugzwang was known to chess players many centuries before the term was coined, appearing in an endgame study published in 1604 by Alessandro Salvio, one of the first writers ...

Bobby Fischer
Robert James Fischer (March 9, 1943January 17, 2008) was an American chess grandmaster and the eleventh World Chess Champion. A chess prodigy, he won his first of a record eight US Championships at the age of 14. In 1964, he won with an 11–0 score, the only perfect score in the history of the tournament.

After another qualifying match against Tigran Petrosian, Fischer won the title match against Boris Spassky of the USSR, in Reykjavík, Iceland.

Candidates Tournament
The Candidates Tournament (or in some periods Candidates Matches) is a chess tournament organized by FIDE, chess's international governing body, since 1950, as the final contest to determine the challenger for the World Chess Championship. The winner of the Candidates earns the right to a match for the World Championship against the incumbent World Champion. Before 1993 it was contested as a triennial tournament; almost always held every third year from 1950 to 1992 inclusive. After the split of the World Championship in the early 1990s, the cycles were disrupted, even after the reunification of the titles in 2006. Since 2013 it has settled into a 2-year cycle: qualification for Candidates during the odd numbered year, Candidates played early in the even numbered year, and the World Championship match played late in the even numbered year. The latter half of the 2020 Candidates Tournament got suspended due to the COVID-19 pandemic and was only played in April 2021.
