Blunder (chess)
In chess, a blunder is a critically bad mistake that severely worsens the player's position by allowing a loss of , checkmate, or anything similar. It is usually caused by some tactical oversight, whether due to time trouble, overconfidence, or carelessness. Although blunders are most common in beginner games, all human players make them, even at the world championship level. Creating opportunities for the opponent to blunder is an important skill in chess. What qualifies as a blunder rather than a normal mistake is somewhat subjective. A weak move from a novice player might be explained by the player's lack of skill, while the same move from a master might be called a blunder. In chess annotation, blunders are typically marked with two question marks ("??") after the move notation. Especially among amateur and novice players, blunders often occur because of a faulty thought process where players do not consider the opponent's . In particular, checks, , and need to be considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wilhelm Steinitz
William Steinitz (born Wilhelm Steinitz; May 14, 1836 – August 12, 1900) was a Bohemian-Austrian, and later American, chess player. From 1886 to 1894, he was the first World Chess Champion. He was also a highly influential writer and chess theoretician. When discussing chess history from the 1850s onwards, commentators have debated whether Steinitz could be effectively considered the champion from an earlier time, perhaps as early as 1866. Steinitz lost his title to Emanuel Lasker in 1894, and lost a rematch in 1896–97. Statistical rating systems give Steinitz a rather low ranking among world champions, mainly because he took several long breaks from competitive play. However, an analysis based on one of these rating systems shows that he was one of the most dominant players in the history of the game. Steinitz was unbeaten in match play for 32 years, from 1862 to 1894. Although Steinitz became "world number one" by winning in the all-out attacking style that was c ...

Each player starts the game with two rooks, one in each corner on their side of the board. Formerly, the rook (from ) was alternatively called the ''tower'', ''marquess'', ''rector'', and ''comes'' (''count'' or ''earl''). The term "castle" is considered to be informal or old-fashioned. Placement and movement The white rooks start on the squares a1 and h1, while the black rooks start on a8 and h8. The rook moves horizontally or vertically, through any number of unoccupied squares. The rook cannot jump over pieces. The rook may capture an enemy piece by moving to the square on which the enemy piece stands, removing it from play. The rook also participates with the king in a special move called castling, wherein it is transferred to the square crossed by the king after th ...

Consequently, a knight alternates between light and dark squares with each move. When moving, the knight can jump over pieces to reach its destination. 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] |

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 was suspended due to the COVID-19 pandemic and was only played in April 2021.

Back-rank Mate
In chess, a back-rank checkmate (also known as a corridor mate) is a checkmate delivered by a rook or queen along the opponent's (that is, the closest to them) in which the mated king is unable to move up the board because the king is blocked by friendly pieces (usually pawns) on the second rank. Introduction Beginners are more likely to succumb to back-rank checkmate, as they are more likely to miss threats in general. At higher levels of play, though the mate itself does not occur very often, play is often affected by the possibility of it—being forced to prevent the mate at all costs may leave a player vulnerable to other threats and tactical ideas they might be more likely to miss. Back-rank mates are often guarded against by a friendly rook or queen protecting the back rank. It may be possible, however, for the attacking side to deflect one of these pieces away from defensive duties, sacrifice a queen for one of them, or exchange one of them, or the pieces may simp ...
