GM
Borislav Ivkov - GM Viktor Kortchnoi;
[E19]
Wijk aan Zee, 1968.
1.d4
e6; 2.c4, {Diagram?}
This allows a transposition back
to QP openings.
[ 2.e4
d5; is a French Defense. ].
2...Nf6; 3.Nf3
b6; {Diagram?}
The Queen's Indian Defense.
[ The move 3...d5; transposes
to
a "Queen's Gambit Declined." ].
4.g3
Bb7; 5.Bg2
Be7; 6.0-0
0-0; 7.Nc3
Ne4;
8.Qc2!?, {Diagram?}
A good move - and a line
that is still popular today.
[ 8.Bd2
].
8...Nxc3; 9.Qxc3
Qc8!?; {Diagram?}
Interesting.
[ Modern theory prefers:
9...c5; with good play. ].
10.Rd1
d5; 11.cxd5
Bxd5; 12.Ne5
Bxg2;
13.Kxg2
Qb7+; 14.Qf3
Qxf3+; 15.Kxf3
f6;
16.Nd3!?,
{Diagram?}
This seems to be a slightly awkward square for
the Knight. (Reshevsky does not comment.)
[ 16.Nc4
]
16...Nc6; 17.Nf4!?,
{Diagram?}
An inaccurate move, but not deserving of the full
question mark that Reshevsky gives it.
(Maybe dubious.)
[ Better was: 17.Be3
].
17...e5; 18.Ne6
Nxd4+; 19.Nxd4
exd4;
20.Rxd4
Rfd8; 21.Rxd8+
Rxd8; 22.Be3!?,
{Diag?}
A logical move, and the first choice of many
computers, - yet Reshevsky gives it a (FULL)
question mark!
[ Better was: 22.Bf4!? ].
22...Kf7; 23.a4!?, {Diagram?}
Angling for the end-game, but maybe a bit impetuous.
[
Much better was: 23.Rc1!,
"="
The game then would be COMPLETELY level! ].
23...Ke6; 24.g4
Rd5!?; (Maybe - '!')
Korchnoi finds a nice way to improve his position.
25.Rc1
c5; 26.b3
Bd6; 27.h3
g6; 28.Ke4
Be5;
29.Rc4!?,
{Diagram}
This could be the losing move.
29...Rd1; 30.Rc1
f5+; 31.gxf5+
gxf5+;
32.Kf3
Rxc1; 33.Bxc1
Kd5; 34.Bg5
a6!;
35.Bd8
b5; 36.axb5
axb5; 37.Ba5
c4;
38.bxc4+
Kxc4!; 39.e4
fxe4+; 40.Kxe4
Bc3;
41.Bd8
b4; 42.Be7
b3; 43.Ba3
Bg7; 44.f4
Kc3;
45.f5
Kc2; 46.Kd5
Bf8; ('!') {Diagram?}
A nice decoy theme.
The
following technique by Korchnoi should be
studied closely and
REPEATEDLY!
47.Bxf8[]
b2; 48.Ke6
b1Q; 49.f6
Qb3+; ('!')
Nice - picks off the h-pawn.
50.Ke7
Qxh3; 51.f7
Qa3+!; 52.Ke8
Qa4+;
53.Ke7
Qb4+; 54.Ke8
Qb8+; 55.Ke7
Qe5+;
56.Kd7
Qf6; 57.Ke8[]
Qc6+!; 58.Ke7
Qg6!;
Black is in total Zugzwang.
59.Ke8[] Kc3!; 60.Be7
Kc4!;
"-/+"
White Resigns.
(The RP is good - and the Black King can simply
march to the e6-square.)
Korchnoi's technique was marvelous ...
and virtually flawless!
