Decoy (chess)
In chess, a decoy is a tactic that lures an enemy off its square and away from its defensive role. Typically this means away from a square on which it defends another piece or threat. The tactic is also called a ''deflection''. Usually the piece is decoyed to a particular square via the sacrifice of a piece on that square. A piece so sacrificed is called a ''decoy''. When the piece decoyed or deflected is the king, the tactic is known as attraction. In general in the middlegame, the sacrifice of a decoy piece is called a ''diversionary sacrifice''.Hooper & Whyld (1996), p. 110. ''diversionary sacrifice''. Examples The game Honfi–Barczay, Kecskemet 1977, with Black to play, illustrates two separate decoys. First, the white queen is set up on c4 for a knight fork: :1... Rxc4! 2. Qxc4 Next, the fork is executed by removing the sole defender of the a3-square: :2... Qxb2+ 3. Rxb2 Na3+ 4. Kc1 Finally, a zwischenzug decoys (attracts) the king to b2: :4... Bxb2+ After either 5.K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Overloading (chess)
Overloading (also overworking) is a chess tactic in which a defensive piece is given an additional defensive assignment which it cannot complete without abandoning its original defensive assignment. Examples Krasenkow– Karpov, in the first round of the 2003 Corus chess tournament, reached the diagrammed position with Black to play. As the white rook on f1 is preventing the black queen from giving checkmate by capturing the pawn on f3, Black won immediately with :29... Re1 further pinning the white rook against the king and overloading the rook. White now cannot prevent the black queen from taking the f-pawn: if White tries to protect the rook with 30.Rxe1 or 30.Qc4, then 30...Qxf3. If White sacrifices the rook by playing 30.Kg2, then 30...Rxf1 31.Kxf1 Qxf3+ and loses the other rook with 32...Qxd5. In Liviu-Dieter Nisipeanu– Anish Giri (see diagram), Giri (Black) played :30... Bxh3 overloading the g2-pawn, as 31.gxh3 is met with 31...f3 32.Re3 Qg5+. After 31.Qc3 Bg4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Promotion (chess)
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its . The player replaces the pawn immediately with a queen, rook, bishop, or knight of the same . The new piece does not have to be a previously captured piece. Promotion is mandatory when moving to the last rank; the pawn cannot remain as a pawn. Promotion to a queen is known as ''queening''; promotion to any other piece is known as '' underpromotion''. Promotion is almost always to a queen, as it is the most powerful piece. Underpromotion might be done for various reasons, such as to avoid stalemate or for tactical reasons related to the knight's unique movement pattern. Promotion or the threat of it often decides the result in an endgame. Rules When a pawn is promoted, it is removed from the board, and the new piece is placed on the square the pawn moved to. Any piece may be promoted to regardless of whether it has been captured. Consequently, a player might have two or more quee ...

Passed Pawn
In chess, a passed pawn is a pawn with no opposing pawns to prevent it from advancing to the eighth ; i.e. there are no opposing pawns in front of it on either the same or adjacent files. A passed pawn is sometimes colloquially called a passer. Passed pawns are advantageous because only the opponent's pieces can stop them from promoting. In the diagram, the white pawns on b5, c4, and e5 are passed pawns, and Black's pawn on d4 is a passed pawn. If Black plays ...fxg4, then the black pawn on g4 will be passed, as well as White's pawn on f4. Protected passed pawn A passed pawn that is protected by its own pawns is called a protected passed pawn. In the first diagram in this article, the pawns on the b- and e-files are protected passed pawns. Two or more passed pawns on adjacent files are called connected passed pawns (see connected pawns), and they are very strong. In the diagram at the top, White's b- and c-pawns are connected passed pawns. A pair of connected passed p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chess Endgame
The endgame (or ending) is the final stage of a chess game which occurs after the middlegame. It begins when few pieces are left on the board. The line between the middlegame and the endgame is often not clear, and may occur gradually or with a quick exchange of pieces. The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns. In particular, pawns become more important as endgames often revolve around attempts to promote a pawn by advancing it to the eighth . The king, which normally is kept safe during the game, becomes active in the endgame, as it can help escort pawns to promotion, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. Not all chess games reach an endgame; some of them end earlier. All chess positions with up to seven pieces on the board have been solved by endgame tablebases, so the outcome (win, loss, or draw) of best play by bot ...
