[%csl Ga7,Gb7,Gd6,Ge6,Gf7,Gg7,Gh7] Scheveningen Variation} 6. g4 {[#] Keres
Attack - Karpov: In those cases when it is necessary to win without fail, I
turn to this sharp variation of the unforgettable Paul Petrovich Keres. And
indeed, here I was meeting one of the leaders of the tournament...} Be7 7. g5
Nfd7 8. h4 {The main theme of the Keres Attack is to launch a rapid attack
against the Black Kingside. He will try to castle Kingside to give security to
his own King.} Nc6 9. Be3 a6 10. Qe2 $1 {[#] Karpov: Stronger, and at any rate
more interesting, than 10.Qd2, after which a Black Knight, arriving at e5,
constantly threatens to leap to f3 or c4 (admittedly, after Be2 these
threatened squares are covered, but this is a quieter, more positional
continuation). Instead now the Queen stands on the same file as the Black King,
which creates the preconditions for the combinational thrusts Nc3–d5 or
Nd4–f5. Although many pieces stand on the e-file they are, as a rule,
quickly cleared.} Qc7 11. O-O-O b5 {[#] Karpov: Black provokes the opponent
into a sacrifice, seemingly not fearing its consequences. However, no other
method of piece development for him is apparent, since after castling he would
immediately come under a pawn attack. Here I thought for a long time, deciding
which form of the Knight sacrifice is best.} 12. Nxc6 ({Karpov: Tempting
appears} 12. Nf5 {and, naturally, bad for Black is} exf5 {on account of} ({
But the intermediate} 12... b4 $1 {leads to boundless complications -} 13. Nd5

possible to wait (} 12. f4 {), in order that the opponent should himself
forced me to give up a piece (} b4 13. Nd5 {). All the same the most promising
to me seemed to be the continuation chosen in the game.}) 12... Qxc6 13. Bd4 b4
{Black kicks the Knight and White responds tactically.} 14. Nd5 $1 {[#]} exd5

Re2e8]} Ne5 18. Bxe5 dxe5 19. f4 Bf5 20. Bh3 $6 {[#] Dorfman considers the
text move to be a mistake at what was, in his view, essentially the first
critical moment of the game.} ({He (Dorfman) gives as correct the continuation
} 20. fxe5 Rf8 21. Rh2 $1 {analyzing no further than} Qa5 22. Qf3) 20... Bxh3
21. Rxh3 Rc8 22. fxe5 {As the dust settles, White has three pawns for the
piece. Black's King is also slightly vulnerable in front of those two
dangerous pawns.} Qc4 $1 {[#] Karpov: This manoeuvre, organically linked with
all of Black’s subsequent play, does honour to the resourcefulness of J.
Dorfman. (Translator’s note: Dorfman considers that after his mistake at the
20th move, it is already White who had to play resourcefully.)} 23. Rdd3 Qf4+
24. Kb1 Rc4 {[%CAl Rc4e4] The position is very sharp.} 25. d6 Re4 26. Rhe3 Rxe3
27. Rxe3 Qxh4 28. Qf3 Qxg5 29. Re1 Qg2 {Black is happy to give the Bishop back
in order to neutralize the threat from White's central pawns. He would emerge
with the better endgame.} 30. Qf5 {[%CAl Rf5c8] Of course White declines and
continues with a threat.} Rg6 31. Rf1 {Both players know that the passed pawns
are worth more than the Bishop. White changes the point of attack, targeting
f7 now.} Qd5 {Holding and building pressure on the pawns. White knows that
Black will soon cash in the Bishop so he must choose how the exchange goes
down.} 32. dxe7 Kxe7 33. Qf4 $1 {[#] Dorfman: This is the whole point – on
account of the double threats of 34.Qh4+ and 34.Qxb4+ Black does not manage to
construct a safe position after 33...Kf8. The remainder is a matter of
straightforward technique, taking account of the fact that after the time
control at the 40th move, the game was adjourned.} a5 {White has a majority on
the Queenside and is more advanced in the center. Black has a passer on the
h-file. White is somewhat better but it's going to take some good chess
playing for either player to win.} 34. Qh4+ Ke8 35. Qxh7 {There goes Black's
passer.} Qf3 {Black can't take the Queen but White finds a nice combination to
bring his Queen around to support the Rook.} 36. Qh8+ (36. Rxf3 $4 Rg1+ 37. Rf1
Rxf1#) 36... Ke7 37. Qh4+ Ke8 38. Qc4 {[%CAl Rc4f7,Rf1f7] Driving the Black
Queen back to the second rank.} Qb7 39. b3 {Air to breathe for the King will
allow more activity for the Rook.} Re6 40. Rg1 {White bids farewell to his
e-pawn knowing he can eventually pick off some Black pawns in return.} Rxe5 41.
Rg8+ Ke7 42. Qh4+ Kd7 43. Qf6 Re7 44. Qf5+ Kd6 45. Qxa5 Re5 46. Qd8+ Ke6 47.
Kb2 {After some fancy footwork, White has three pawns to one on the Queenside
and Black's f-passer looks decidedly weak.} f6 48. Rf8 Qg7 $4 {Of course this
pawn is Black's only remaining source of counterplay and he does not want to
lose it, but this blunder is the final nail in the coffin. White will switch
the focus of his attack now.} 49. Qc8+ Kd5 50. Qc4+ {[#] Black resigns knowing
nothing but more pain is coming.} ({After} 50. Qc4+ {if Black were to continue
then} Kd6 51. Rd8+ {with} Qd7 {offering the longest but ultimately futile line
of resistance.} (51... Ke7 {just loses quicker:} 52. Qc7+ Ke6 53. Rd6+ Kf5 54.
Qxg7 {and so on.})) 1-0
