1. e4
c5 2. Nc3 Nc6 3. f4 g6 4. Nf3
As you
probably know, this position denotes the Grand Prix
attack. With proper play, black would equalize --
though
not
without its pitfalls for black.
4...
Bg7 5. Bb5 e6
?! This
gives white a nice game. 5. ... Nd4! gives black
equality. Why, you ask? Several reasons 1) doesn't let
white
double black's pawns on c6 2) let's white's bishop
stay a
target. For example, 6. Nxd4 cxd4 7.
Ne2 Nf6 8. d3?? Qa5+ 3)
the
knight at d4 can't be booted from d4 by c3, since white's
knight
occupies that square.
6. Bxc6
dxc6 7. O-O Ne7 8. d3 Bxc3
? This
severely weakens black's dark squares and his king-side.
More
logical is continued development with 8. ... 0-0
9. Be3
b6 10. Qe1 Ba6, with the idea of ..c4 to undouble black's pawns.
9. bxc3
Qb6 10. c4
! A
strong multi-purpose move. Here's what
it does:
1)
fixes the black c5 pawn, keeping a target 2) controls d5,
so that
black can't use that central square for his pieces when
white
plays an eventual e5 to create an potential outpost for
white's
knight at d6. 3) It evens opens up the a1-h8 diagonal
for
white's bishop.

Bd7 11. Be3 Qa5 12. Bd2 Qc7 13. Bc3 Rg8
Good. You didn't fall for 13. ... O-O? 14. Bf6!
Rae8 15. Qe1
with a
winning king-side attack.
14. Be5
Dubious. This should've forced black to go to his
most active
square
(...Qa5). White has a MUCH stronger
move instaed -- 14. Bf6!
This
would put a massive cramp on black.
Black can't mobilize
his
king-side or center, he can't castle, and he can't even take
white's
f4 pawn. (14. ... Qxf4 15 Ne5 with a clear advantage
for
white. Try to work it out). White's bishop is a far
superior
piece to black's knight at e7.
14...
Qc8 15. Bd6 b6 16. Bxe7
This
isn't bad, but again -- white's bishop is far superior
to
black's knight. Why shouldn't white
intensify pressure on
the
dark squares with Qe1, with the idea of Qh4.
16...
Kxe7 17. e5 b5 18. Qe1 Rh8 19. Qf2
?! This
cashes in too early. White's winning
chances in the
middle
game are excellent. 19. Ng5 with the
idea of Ne4, and
possibly
Qh4, leaves white with a great game.
Notice that white
is
pratically a piece up, because of the limited scope of black's
bishop
on d7, compared to white's knight.
19...
Qf8
! A
resourceful move! Black's chances
aren't great, but
certainly
they are better in the endgame than the middle
game. This is because black's king stuck in the center
is a
drawback in the the middle game, but an advantage in
an
ending.

Qxc5+ Ke8 21. Qxf8+ Kxf8 22. c5 a5 23. a4
I don't
like this move (though it is okay). I'm
sure white's
idea
was to create a target on a5 and to create a potential
reroute
for his knight (Nd2-c4), but his was unnecessary since
white
could always reroute by Nd2-e4. I like
23. a3, keeping
white's
pawn opposite black's bishop (hence not a target).
Here's
a general rule to remember -- the farther advanced a
pawn
is, the more vulnerable it is.

Kf2 f6
Notice
that if white would have posted his knight in the center
(e4),
this break would not even be possible.
30. Ke2
Be8 31. exf6+
Simply
31. c3 would've won a pawn for white.
Note that earlier,
c3
wasn't possible because after the exchange of rooks on b7,
black
could've played ...c2! and white could not have stopped
the
pawn. It doesn't work now, however,
because the white
king is
within range of the c-pawn.
31...
Kxf6 32. h4 Rd7 33. Nd6 Ra8 34. d4 Rad8 35. Kd3 Rxd6
Good! I would've done this myself. Passive play is sure
to lose
-- active play is black's best chance.

Ba4
? This
gives white winning chances. Even in an
endgame,
activity
of yoru pieces is paramount. 53. ...
Bc6! draws
by
force AND has a subtle trap. If 54.
Kxg6?? b1Q+ 55. Rxb1 Be4+
would
force white to resign! And if white
tries Rxb2 instead of
Kxg6,
then Be4 sets up a fortress. This is a
common motif for
the
side with less material. White's rook
for bishop in that
position
would be worthless.
54.
Rxb2 Kxg3 55. Kxg6
? White
throws his win away. 55. Kg5! preserves
the win.
The
idea is to drive black's king away with a check on the
third
rank, then pick off either the e6 or g6 pawn, and finally
to
sacrifice the rook at the right moment to get a winning K + P
endgame.
