{Hermansson was surely heading towards the GM-norm when he won a pawn against
the nr. 1 seed Russian Volkov, but one of the defining differences between the
east and the west in chess has always been that close to all Russian's have
studied the endgame and have a good technique. This comes from having trainers
and some kind of organised training systems in the Soviet days. There is still
a tradition that when strong players feel they are over the hill, they
consider taking a pupil.  In the west however we have always been on our own,
or autodidact as it is called with a fancy word. This means that our way of
learning chess has been less organised and often also poorer. Especially when
it comes to the tediousness of the endgame. This is also the case for
Hermansson, who has played the opening very well and won a pawn. Now however
it is time to convert this into a full point.} 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4.

improve the position of his king and only then look for a good moment to force

win.}) 44. hxg6 {Now the Black pawns are divided, and therefore easier to
attack. White should be able to use this to create enough counterplay to make
a draw. Still after 44...fxg6 there might be some practical chances. After the
recapture with the rook the h-pawn is isolated and represents a serious
liability to Black.} Rxg6 $6 {The rest of the endgame is still interesting,
but it did not seem to ever give Black real winning chances again. Therefore
we stop here. Black drew on move 86.} 45. e4 Kc7 46. Ra1 Kb6 47. Rb1+ Ka7 48.

line where the Carlsbad pawn formation occurs frequently. Of course, Black
does not have to play 5...Ne4 (he may try 5...c5) or 7...e6 (7...c6 is
possible). But, in general, this pawn structure is most typical for the 5 Bg5
line. A few things are quite specific for this variation, as White has
exchanged the bishop for a knight at an early stage. First,a b2-b4 advance is
easier to manage, as we can see in this game (Black's bishop does not control
the b-square). Black cannot yet occupy the e4-square with his knight. On the
other hand, Black has some advantages, too. White cannot occupy the e5-square
with his knight. Black's light-squared bishop might be developed to g4. When
White goes for b2-b4, Black's knight may take a short route to the c4-square
via d7 and b6. In addition, Black has available to him a plan for advancing
his f-pawn. Let us see all of this in action:} O-O 10. e3 Be6 11. Be2 Nd7 12.

1. d4 Nf6 2. c4 g6 3. Nc3 d5 {Not a surprise. The Grünfeld has become Kamsky's
usual "pet" line in matches, and it worked pretty well in the quarter-final
against Topalov.} 4. Bg5 {Gelfand chooses a solid line which is in accordance

White so far, and stays faithful to this approach once more.} Ne4 5. Bh4 Nxc3

{Overall this is a brilliant game played by Tomashevsky. In the first half of
the game he was able to gain a nice advantage and after that his technical
performance was just top notch.} 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Bg5 Ne4 (4...
Bg7 5. Bxf6 Bxf6 6. cxd5 c5 {is a completely crazy line which has been
becoming popular recently.}) 5. Bh4 c5 6. cxd5 {Six minutes for this move?!!
It surely meant that Tomashevsky had not prepared this line right before the
game. He had to recollect the bits he had in his mind regarding this opening.}

moves in this position. But Tomashevsky thinks for nine minutes and comes up
with a novelty.} 13. h3 $5 {Some kind of waiting move asking Black to define
his intentions.} (13. Nd2 e5 14. Bf3 e4 15. Be2 $14 {Thanks to his compact
pawn structure, White has scored very well from this position.}) (13. Qb3 Qxb3

position? Who cares? Who would like to defend such an endgame right out of the
opening?}) 13... Rac8 (13... e5 $6 14. dxe5 Qxd1 15. Rfxd1 Nxe5 16. Nd4 Be4 17.

going to cause the lot of difficulties for the black rooks to come into the
game.}) 14. Qb3 Qxb3 15. axb3 a6 {This is not a move that Black would have
been very happy to make especially with the knight on f3 having a clear route
from f3-d2-c4 looking at the b6 weakness. But in any case I feel that this
endgame is quite unpleasant for Black to play.} 16. g4 $5 {Thirty minutes for
the move g4. I am sure that Tomashevsky was thinking whether the move g4 was
required or not. Finally he decided that this was the best use of the move h3.}

position that has been reached at the board after 28 moves. Who is better and
why? At first glance it seems like Black should be better because he has the
outside connected passers. But this would be a very superficial assessment.
The important thing to note is that these pawns cannot be pushed easily. At
the same time the bishop can be stationed on a square like f3 very well while
it is very difficult for the black knight to find an outpost. One of the
reasons for the knight not having a fixed point is that the bishop controls
the light squares and the pawns f2-e3-d4 control the dark squares. Together
they make an impressive team. White's central pawns are also difficult to move
but he will first try to create a second weakness by pushing his h- and
g-pawns. To write these words is quite easy but to put them into effect on the
chess board is extremely difficult. That's why Tomashevsky is one of the best
players in the world. Have a look at how beautifully he converted this
position into a win.} b5 29. Bf3 Nb6 30. Ra2 Na4 {The knight tries to shield
the a6 weakness but soon it will have to move as White can always attack it
with Bd1.} (30... Nc4 31. Be2 Rc7 32. Rc3 $16) 31. Rc2 Rd6 32. g5 Kg7 33. h4 h6
34. Kg3 hxg5 35. hxg5 f6 36. gxf6+ Rxf6 {Has Black benefitted by employing the
f6 and h6 breaks or has he made it easier for White to push his pawns? I think
with the breaks out of the way, White now knows exactly what he is facing. It
might have made sense to keep the breaks in reserve. But what should have
Black done if not for f6 and h6. He doesn't have anything constructive and
could have just shuffled his pieces from here to there - something which is
difficult for us human beings.} 37. Ra3 Rd6 38. Bd1 Ra7 39. Rca2 Nc5 40. Bc2 (

material and hence Khairullin resigned. A very consistent game by Tomashevsky
who hardly made a bad move.} 1-0
