Swiss system tournaments, a type of group tournament common in chess and other board games, and in card games such as bridge, use various criteria to break ties between players who have the same total number of points after the last round. This is needed when prizes are indivisible, such as titles, trophies, or qualification for another tournament.
A variant first described by Claude Shannon provides an argument about the game-theoretic value of chess: he proposes allowing the move of “pass”. In this variant, it is provable with a strategy stealing argument that the first player has at least a draw thus: if the first player has a winning move in the initial position, let him play it, else pass.
Chess strategy is the aspect of chess play concerned with evaluation of chess positions and setting goals and long-term plans for future play. While evaluating a position strategically, a player must take into account such factors as the relative value of the pieces on the board, pawn structure, king safety, position of pieces, and control of key squares and groups of squares (e.g. diagonals ...
The Sämisch Variation of the King's Indian Defence is a chess opening that begins with the moves: 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3. The Sämisch is a subtle blockading system and a critical challenge to the King's Indian. [1] It is named after the German grandmaster Friedrich Sämisch.
The Buchholz system (also spelled Buchholtz) is a ranking or scoring system in chess developed by Bruno Buchholz (died c. 1958) in 1932, for Swiss system tournaments. It was originally developed as an auxiliary scoring method, but more recently it has been used as a tie-breaking system. It was probably first used in the 1932 Bitterfeld tournament.
The Hippopotamus Defence is a chess opening system employed by Black, consisting of a double fianchetto structure (bishops on b7 and g7) and a small pawn centre (pawns on d6 and e6). The knights are typically developed to e7 and d7 and the rook's pawns to a6 and h6. [ 1 ]
The Lucena position is a position in chess endgame theory where one side has a rook and a pawn and the defender has a rook. Karsten Müller said that it may be the most important position in endgame theory. [1]
Traditional chess strategy would have frowned upon Black's setup, since their pieces have little room in which to manoeuvre. In the early 1970s, " 'hedgehog' was a generic term for any setup that was cramped, defensive and difficult to attack", but today refers specifically to this formation. [ 1 ]
