Grandmaster Gopal. I had been the member of the Indian Team which won the
Bronze medal in the Asian Games and World Team Championship. Today, I would
be discussing a very important theme in chess middlegames i.e. the positional
exchange sacrifice. Exchange Sacrifice in pure chess terms is a 'trade off'
between a rook and a minor piece. The side which resorts to an exchange
sacrifice may have the following objectives: 1) To weaken opponent's king 2)
to seize more squares 3)to shatter opponent's pawn structure 4) to eliminate
opponent's active piece Exchange sacrifice is typical to certain chess
openings: For eg ...Rc3 is a typical exchange sacrifice in most of the opening
systems of the Sicilian Defence. Similary ...Re3 is a typical exchange
sacrifice in closed openings like Kings Indian Defence and the Modern Benoni
The ''exchange sacrifice has also been a trademark of some world class
players'' like Veselin Topalov. In this game we would be seeing an example of
exchange sacrifice with ...Re3.} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 c5 5. Nge2

Nbd7 13. Be3 Ne5 14. h3 Re8 {The position is round about equal. White probably
overstimated his chances and chose a wrong plan.} 15. b4 $6 {[%csl Rc4] By
this move White intends to expand on the queenside . But in this process white
failed to foresee black's plan.} (15. Nc2 {would have been a more prudent
choice.}) 15... Bb6 16. Qb3 {Choosing a square for the white queen a difficult
task. The text is suitable for offering support to the weakened c4 square, and
for promoting white's plan of pushing his queenside pawns. But the downside
of this move is quite evident as after Qb3 as the white's minor pieces on d4
and e3 are deprived of support. With the Queen on d2 white's position would
have been perfectly playable.} Bd7 {Black plays quite logically,he intends to
bring the only inactive piece in the game i.e. the rook on a8 to the open
c-file} 17. a4 Rc8 18. Rac1 Ng6 $1 {[%csl Gb6,Gd7,Rg1,Gg6][%CAl Gg6h4][%mdl
32768] I already prefer black as all of black's pieces are positioned ideally.
The black's knight on g6 as well as the light squared bishop on d7 are
perfectly positioned for organising an attack on the kingside.} 19. Rfd1 $2 {
[#] White fails to foresee black's positional threat} (19. Rfe1 $142 {black
can consider the positional sacrifice} Rxe3 $5 (19... Nh4 $40 {is quite
promising for black}) 20. fxe3 Qe7 21. Bf1 Qe5 $5 {With great play on the dark
squares. However Rfd1 is clearly a mistake after which black gets decisive
tactical ideas.}) 19... Rxe3 $1 $17 {[%mdl 32768] A beautiful sacrifice by
which black weakens/destabilizes the position of the white king as well as
takes control of the dark squares.} 20. fxe3 Qe7 {Black has managed to achieve
the following objectives: 1) weakened the position of the white king 2)
created many 'weak spots' like the pawn on e3 in white's position} 21. Na2 {[#]
} (21. Kh1 Qxe3 $19) (21. Rd3 Bxd4 22. exd4 Nf4 $19 23. Rf3 Rxc3 24. Rcxc3
Nxe2+ {and black wins on the spot}) 21... Rxc1 $6 (21... Re8 $1 {was by far
the best move yielding black a decisive advantage} 22. a5 Ba7 23. Bf3 Nh4 $17 {
[%CAl Ge7e5,Ge5g3,Gd7h3] black threatens to re-route the queen to g3 via e5})
22. Nxc1 {[#]} Bxa4 {this move is a simple illustration of the tactical
motives in the position} (22... Nh4 $1 $17 {[%CAl Ge7e5,Ge5g3,Gd7h3] would
have been even stronger. Black intends to play Qe5 i.e to re-route the black
queen to g3}) 23. Qxa4 Qxe3+ 24. Kh1 Ne4 $4 {This was a blunder} (24... Bxd4
$17 {was the simplest as well as the strongest move}) 25. Nf5 $2 {White
returnes the favour} (25. Qe8+ $1 Nf8 26. Ne6 $1 fxe6 27. dxe6 Nf2+ 28. Kh2
Qxe6 29. Qxe6+ Nxe6 30. Re1 $18 {is far from clear.}) 25... Nf2+ 26. Kh2 Qe5+

was neatly conducted by Topalov. Studying this game in detail would
certainly enrich the players with the typical patterns of exchange sacrifice.}
