Queen : The strongest piece on the board.

Queen : The strongest piece on the board.
Most of the historians agree with the fact that Chess is originated in India. The commercial and cultural intercourse between the Persia and India took the game to Persia and then to West. During the ancient period when the chess was known as ‘Chaturang’ in India there was no piece known as ‘Queen’. But instead there was a piece known as ‘Mantri’ (The canceller of the King). Since He was second to the king he has limited mobility unlike the modern Queen has. In Arabic language ‘Mantri’ is called as ’ Wazir’ and still now in regional languages in India Queen is called as ‘Vazir’.
The moves of kings, Rooks and Knights in Chaturang were the same as they now, the absence of a Queen (Which even in the two handed chess was long only represented by a piece with the single square move) and the limited power of the Bishops and pawns must have made Chaturang a dull affair.
When the King was the tallest cylinder on the board, the Mantri was the simply somewhere small stick of wood. Later, when the piece acquires royal characteristics (as the Queen), she was represented as an image, somewhat shorter than King.
It was the original Sanskrit practice to station the Kings on different files and to place each counselor on his master’s left. Thus the queens did not face each other, are they do in the initial position of modern chess. By the Ninth century, however, the Arabs were stationing the king and counselor in their present positions.
William Hone, Year Bok of 1832 writes,
“Strangely inconsistent with our ideas of propriety and probability, the Queen is the chief character in the contest. She is not merely the soft excitement of the war who bids her king go fourth with her blessing; no, she is the active, undaunted, indefatigable leader of an army, herself a host!”
Modern Queen has the advantage of moving as a rook, in straight forward, backward and sideway, to the extent of board, and as a Bishop, diagonally, with the same range. This power of mobility made the Queen most powerful piece on the battle ground.
Place the Queen on e4-square i.e the centre, it controls 27 squares besides the one she stands on.
There are the guidelines while mobilizing it,
·        The Queen should be rarely used to defend or attack any point if you can do it as well with a subordinates.
·        It is not good to play the queen out in the game at the beginning, because she can be attacked by inferior pieces and is compelled to retire with the loss of many moves.
·        Being the strongest piece in the army, its safety has the paramount importance.

The Pawn : Infantry in the King's Army

The Pawn : Infantry  in the King’s Army.
The pawn is considered as the weakest piece. There are eight pawns on each side occupying the squares in front of the other pieces. These pawns are also called as the infantry in the king’s army. The pawn has very peculiar movement. It can move one square forward if it is clear. The pawn on its starting rank can move two squares. Another peculiarity is that it cannot move backward, that is why one has to be very careful when advancing a pawn.
The pawn can capture diagonally, one square forward either to left or right. Another unusual move is the en-passant capture.
Pawn, even though the weakest soldier of the army , keeps the ability of promoting to queen. In the course of the game a pawn advances to the other end of the board. When it reaches the other side it gets promoted to another piece of that player’s choice. Generally queen is chosen for promotion and it is called as queening.  Sometimes the piece is chosen other than queen is called as underpromotion. Most of the time the piece selected is Knight, when the position demands.  The position when there is a chance to checkmate or when the possibility of Fork.

Annihilation of Defence

Pin It

Annihilation of Defense :
Annihilation of defense is the tactics of removal of defender. The key defender can also be removed by deflection, overloading, pin, decoying or other methods. In the method of annihilation of defense the defender is removed physically either by exchange or sacrifice. Every chain has a weak point. The skill is in searching for this weak point. At particular situation the defenses become exhausted. The weakness is generally found in the place where the key point is defended by only one piece. Removing this piece either by sacrifice or exchange and exploiting the weakness is the knack.
To find such weakness the player should search for,
1.       Which pieces are under attack?
2.       Find the defenders of the pieces that are under attack.
3.       Can you capture the defender either by exchange or sacrifice.
See the example.


Petrosian - Ivkov
Beograd, 1979
Black King has the limited mobility. The pawn on e5-square is weak, if not defended by the Black Bishop on d4. If this Bishop is picked up the Black's position deteriorates. 1.Rxd4! [ 1...exd4 2.Re5+ Kxg4 3.h3# ] 1–0

Example 2


(2) Annihilation of defence.
White Bishop is defending the castle sides pawn. Removal of this defender will open the king.  1...Qxf3 2.gxf3 Rg6+ 3.Kh1 Bh3 4.Rd1 Bg2+ 5.Kg1 Bxf3+ 6.Kf1 Rg2 7.Qd3 Rxf2+ 8.Kg1 Rg2+ 9.Kh1 Rg1# 


Annihilation of defence.
Black Bishop on f8-square is defending the king. White Queen is applying skewer at the Bishop. Use this positional benefit to exploit.  1.Rxf8+ Kxf8 2.Nf5+ Kg8 3.Qf8+ Kxf8 [3...Kh7 4.Qg7#] 4.Rd8
