Prophylaxis (chess)
In chess, prophylaxis consists of a move or series of moves done by a player to prevent their opponent from taking some action. Such preventive moves, or ''prophylactic moves'', aim not only to improve one's position but also to restrict the opponent in improving their own. Many standard and widespread opening moves can be considered prophylactic. One common prophylactic idea is the advance of the near a castled king, which can be done to provide luft and/or to prevent a pin; another is to transfer one's king to the b-file after castling queenside so as to protect an unmoved a-pawn, among other purposes. Prophylaxis is a distinctive feature of , often preventing opponents from entering risky, double-edged lines, as well as punishing opponents who play too aggressively. Using prophylaxis is an essential skill at advanced levels of play. Famous practitioners of prophylactic play include Aron Nimzowitsch, Tigran Petrosian, and Anatoly Karpov; even players, such as Mikhail Tal ...

Flight Square
In chess, a flight square or escape square is a safe square to which a piece, especially a king, can move if it is threatened. Providing one's piece with flight squares can prevent the opponent from winning material or delivering checkmate. For example, in the Morphy Defence, the white c-pawn may be advanced to provide the light-squared white bishop with a flight square. Conversely, it is possible to take away an enemy piece's flight squares, known as domination. Luft In chess, (the German word for "air", sometimes also "space" or "breath") designates the space or square left by a pawn move into which a king (usually a castled one) may then retreat, especially such a space made intentionally to avoid back-rank checkmate. A move leaving such a space is often said to "give the king some luft". The term "luft", "lufting", or "lufted" may also be used (as an English participle) to refer to the movement of the relevant pawn creating luft. (At the 45:26 mark, GM Ben Finegold ...

Pin (chess)
In chess, a pin is a tactic in which a defending piece cannot move out of an attacking piece's line of attack without exposing a more valuable defending piece. Moving the attacking piece to effect the pin is called ''pinning''; the defending piece restricted by the pin is described as ''pinned''. Only a piece that can move any number of squares along a horizontal, vertical, or diagonal line (i.e. a bishop, rook, or queen) can pin. Any piece can be pinned except the king. The pin is one of the most powerful chess tactics. The inverse of a pin is a ''skewer'', in which a more valuable piece under direct attack may move to expose a less valuable piece to an attack. Types Absolute pin An ''absolute pin'' is one where the piece shielded by the pinned piece is the king. In this case it is illegal to move the pinned piece out of the line of attack, as that would place one's king in check (see diagram). A piece pinned in this way can still give check or defend another piece fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
