Middle game Strategy Part 17.

Pin It




White to play

1. Qd2 {d4 is a weak square and a best support point for white's Knight.
c7-square is also weak and if white can bring its knight to this point it can
fork Rook and King. b4 will chase away the Black's Queen. e4 is a weak
square and Black can try to exploit it by gaining complete control over it.}
Bb7 2. Rfd1 d6 3. a3 h5 4. Rc2 Bd4 {Exchanging Bishops can give Black a
complete control over e5-square since it is a black square.} 5. b4 Qe5 *

Imbalances.

White is developed excellently and built up his attack in the
best possible way. Black has two which are not active in the game where as
white's rooks are active and are posted on the open or semi-open files. White
Bishop is excellently posted into the opponent's territory on g5. White has
also formed the battery on open d-file. Black has d7 and d6 weakness Black
should think of exploiting weak f7 square. b7 is also a weak pawn. Blakc's
queen is entered right into the White's territory and in many positions a
single avantgrade, here Queen, can disrupt the opponent's forces. Because
white cannot move with absolute freedom within his own territory, he will find
it more difficult to coordinate his attack. If we find attacking the d6 or
f6 suare the strategy will to develop the pieces accordingly.} 1. e5 {d6 pawn
cannot capture it since the Bishop behind it is not sufficiently guarded.} Qf5
2. Kb1 {This is the impressive move because it leaves the e-pawn hanging once
again. This move is called as Hector's homecooking because this most dangerous
move is not the computer move.} (2. exd6 Qxg5 3. Qxg5 Bh6 4. Qxh6 Rxh6 5. Bf3

Knight on the e4 square since it will control the two weakness of white viz d6
and f6. But there is one another interesting weakness in the Black's camp ie.
c7.} d4 $2 {Its a grave mistake. Black should have done something to develop
the pieces.} 4. Nxd4 Nxd4 5. Qxd4 Qxg5 6. Ne4 Qd8 7. Bxh5 Bg7 8. Bxg6 Rxh1 9.

Example of  Overloading Work
Imbalances.

d4-Knight and g5- Bishop both are guarded by the White Queen
This is called as the overloaded Work and such overloaded work can be
exploited. Can Black Exploit this situation? If Black can entice the White
queen to leave the crease then these two pieces will be left hanging and
stumping can take place. Black has a Backward pawn on d6. If white gets
opportunity it will be ready to exploit it. Can Black exploit such situation?}
1... Nfxe4 (} 1... a5 2. Rad1 Qc7 3. Be3 Rd8 4. Rf2 b6 5. Bg5 Re8

Qxg5 5. Qxd6 {( If you observe you can see that both sides have equal material
but the White has inferior pawn structure.)}
