move for the first time in my practice.} 10. Bf4 {In my well-known book "1. d4

the Bf4-idea.} Nbd7 11. a4 $1 {Having done some homework on this line, I
remembered that eventually I came to the conclusion, that this useful move is
the most accurate one in this concrete position. White's main choices here are
11. h3 and 11. Re1, but somehow I got the feeling that I needed the pawn on h2

decision, typical of the Benoni opening, Black gets a nice c5-square for his
knight, but his activity appears to be only a short-term factor, while his
structural problems start to tell in the long term.} ({The correct decision
would have been} 15... b6 {, still I like the white position here, as I have a

1. d4 Nf6 2. c4 e6 3. g3 c5 {An unusual opening choice for Kramnik. After he
played this move I understood we would have a big fight.} 4. d5 exd5 5. cxd5 d6
6. Nc3 g6 7. Bg2 Bg7 8. Nf3 O-O 9. O-O Re8 10. Bf4 a6 11. a4 h6 $5 {This
wasn't some elaborate preparation from Vladimir. He just wanted to take the
game into original channels, far away from opening theory. The move itself is
probably a bit dubious, but over the board it isn't so easy to refute.} 12. Re1
({It was probably more accurate to first play} 12. Qc1 {, which is similar to
the game, but gives White extra options. For example,} g5 13. Bd2 Bf5 14. h4 g4
15. Ne1 $1 {, and next White will play Nc2 and Ne3, with an advantage.}) 12...
Bf5 13. Qc1 ({After} 13. Nh4 Bc8 {, due to the threat of ...g5 White will
either have to acquiesce in a repetition (with Nf3 Bf5, etc) or retreat the
bishop from f4, which is a clear concession.} 14. Bd2 Nbd7 {, is totally fine
for Black.}) 13... g5 ({In case of} 13... Kh7 14. Nh4 Bc8 15. Qc2 $1 {was my
idea, preventing ...g5. Now after} Kg8 16. Nf3 Bf5 {White has the option of}

what I was mainly concerned about during the game.} 15. Nxe4 Bxe4 16. h4 $1 {
was my intention, with the following possible variations:} Bxf3 (16... g4 17.
Nh2 Bxg2 18. Kxg2 h5 19. Nf1 {is better for White. After Ne3 the f5-square
will be very weak.}) 17. Bxf3 gxh4 18. Bxh6 hxg3 19. Kg2 $1 gxf2 20. Rh1 {
starts a strong attack against Black's king.}) 15. h4 {Forcing Black's
kingside pawns to advance. On the one hand, Black gains space and creates an
outpost on e5 for his knight, but the long-term kingside weakness will be more
important.} g4 16. Nh2 {Now the knight looks a bit clumsy; soon, however, it
will move to e3.} Kh7 ({Kramnik suggested} 16... h5 {as an improvement after
the game. I still think White has an advantage after} 17. Nf1 Ne5 18. Bg5 Qd7
19. Ne3 Bg6 20. a5 {, which is pretty similar to the game.}) 17. Nf1 Ne5 18.
Bf4 Bg6 19. Ne3 h5 20. a5 {Now White has a pleasant advantage. Black is
deprived of counterplay, but his position is very solid so it won't be easy
for White improve.} Qc7 21. Ra4 Kg8 22. Qd2 {It feels like I misplayed the
position a bit around here and allowed Black too much counterplay. However, it
isn't easy to find the correct plan for White. Normally White should prepare
b4, but it won't be easy because of the unstable knight on c3.} (22. Qa1 $5 {
may have been more accurate. White will continue with Rc1, Qa3 and then
consider playing b4 at the right moment.}) 22... Nfd7 23. Ra2 ({I could have
played the ambitious} 23. Be4 $5 b5 24. axb6 Nxb6 25. Bxg6 Nxg6 (25... Nxa4 26.
Bxh5 Nxc3 27. bxc3 {gives White an initiative.}) 26. Re4 {I wasn't sure about
this position over the board, but in the absence of Black's counterplay the
weakness of f5 will tell.}) 23... b5 ({It was also possible to just wait with} 
23... Nf6 {, but naturally Vladimir wanted to start his own counterplay.}) 24.
axb6 Qxb6 (24... Nxb6 25. b3 {, and next Be4 will be very unpleasant for Black.
}) 25. Be4 $2 {A very big mistake, which leads to a fascinating position!} ({
If I had just protected my pieces before starting action:} 25. Rea1 {, I
could've counted on a big advantage.}) 25... Bxe4 26. Nxe4 Ng6 {Now for the
sake of consistency I had no choice but to go for the following line:} 27. Nxd6
Nxf4 28. Nec4 Nh3+ 29. Kf1 (29. Kg2 {was much more accurate considering what
follows.}) 29... Qb8 30. Nxe8 Qxe8 {After some brief fireworks we've landed in
an extremely unusual position. In terms of material the game is relatively
balanced, but the unusual configuration of the pieces, especially the knight
on h3, makes the position extremely complex and hard to understand.} 31. Qc2
Ne5 32. Nd6 $6 {This move loses a few tempi. I didn't understand that the
knight will be weak rather than strong on f5!} (32. Ne3 {was a more accurate
move.}) 32... Qd7 33. Nf5 Bf8 {Black had a spectacular opportunity to take
over the initiative, but this misses it.} (33... c4 $5 {threatens ...Nd3 and
would have posed significant problems for me.} 34. Nxg7 ({The move I intended
to play,} 34. Qe4 {would be met by the stunning} Bf8 $3 35. Qxe5 Re8 36. Qf6
Qxd5 {and Black wins because of the threat of ...Qh1!}) 34... Kxg7 35. Qe4 f6 {
and as always it's very hard to assess this irrational position. Will the
knight on h3 turn out to be a weakness or an asset? For the moment it helps in
the attack against White's king, so Black can claim a certain advantage, but
the result of the game is totally unclear.}) 34. Ne3 $1 {Well I managed to get
my knight to e3 in three moves instead of just one! But not much harm was done,
and White is pretty much okay after this move.} (34. Rd1 $2 c4 {would really
become unpleasant. The threat of ...Nd3 is difficult to prevent.}) 34... c4 35.
Qf5 Qxf5 36. Nxf5 {The trade of queens lessens the danger to White's king.
Also the passed d-pawn may become an important force in the future.} Bb4 ({
More testing would have been} 36... Bc5 {, when White has to find the strong}
37. f4 $1 (37. Rea1 Nxf2 38. Rxa6 Rxa6 39. Rxa6 Ne4 {, and after the knight
has returned from limbo White will face an unpleasant defence.}) 37... gxf3 38.
exf3 Nxf3 39. Rea1 {White has very good chances to make a draw because of the
activity of his rooks and d-pawn.}) 37. Rd1 a5 {The position remains
complicated, but White is already out of danger.} 38. Raa1 ({In fact, I could
have already started active counterplay with} 38. d6) 38... f6 39. Rac1 $6 {
A pointless move.} ({If I play some logical moves the game will be balanced.
For example,} 39. d6 Kf7 40. Kg2 Rd8 41. f3 {, and perhaps Black should go for
the repetition with} Kg6 42. Ne7+ Kf7 43. Nf5) 39... Bc5 {Now I'm already
slightly worse again.} 40. Nd4 Kf7 41. Kg2 Rb8 42. Rc2 Rb4 43. d6 $1 {The
situation was becoming a bit too murky, so I decided to think a while and
calculate things till the end. So I made this concrete move which forces a
draw.} (43. Nc6 $6 Nxf2 44. Nxe5+ fxe5 45. Rf1 Ke7 46. Rxf2 Bxf2 47. Kxf2 Kd6
48. e4 a4 {is a variation I calculated. The ending is very unpleasant for
White due to the passivity of my rook.}) (43. f4 gxf3+ 44. exf3 (44. Kxh3 {
unfortunately runs into the nice tactical shot} Ng4 $1 {, threatening decisive
forks on e3 and f2.}) 44... Nd3 {looked very dangerous to me during the game,
but the ruthless computer says it's just equal after} 45. Nc6 Nhf2 46. Nxb4

chance to cause White some problems.} 50. Ra2 $1 (50. Rxc3 Be1 51. Ra4 Bxc3 52.

has a rather dodgy reputation. I sometimes find myself involved in discussion
on the topic: "Which is the more dubious opening; the King's Indian or the
Modern Benoni?" The answer fluctuates, but lately it seems the MB has been
more under a cloud than the KID. However, I believe there are few GMs who
would claim that the fianchetto is the most critical setup against the MB. The
reason why so many strong players play it has more to do with the fact that it
suits their repertoire (early g3), or that it is less sensitive to theoretical
novelties (I'm guessing now). So, from a MB perspective, Black is already
quite happy to have avoided the most challenging lines, while still being able
to play the Benoni structure.} 6. Bg2 d6 ({Black can try to do without d6 for

known as a classical player. After so many years of experience, he seems to

follow the way he treats a hyper-modern opening.} Nbd7 $5 {Usually, this move
is played after inserting 9...a6 10.a4. In most of the cases, it leads to a
transposition anyway, but this will not be the case here. Before moving on, I
would make some general remarks. In the fianchetto Benoni, the old fluent plan
based on Nd2-c4 offers Black good chances for counterplay. The lines based on
Bf4 (with or without a previous h2-h3) are more disturbing. As we will see,
the omission of ...a6 is aimed to meet this plan more flexibly than in the
main lines. The temporary knight's stability on b6 is essential.} 10. a4 {

the minimal material investment, Black has excellent development and strong

but apparently Topalov thought that he can afford to play normal moves, as if
nothing had happened. Of course, only further practice will prove whether the
sacrifice is entirely correct. A long time ago, I learned from GM Mihai Suba

while black's knight on d7 is one of his most flexible pieces. The Q is headed
for f8 where it will preserve the Bg7, guard d6, support the kingside and help
