1. e4 e5 2. Nf3 Nc6 3. d4 $5 {[pgndiagram] The Scotch! This opening made it's
debut on the modern chess scene when Garry Kasparov used it in 1990 match
against Karpov (and scored 1.5/2). Magnus Carlsen also played it on occasion,
while So used it only twice in his life (last time to beat Aronian in 2015
Tata Steel Tournament).} exd4 4. Nxd4 Nf6 5. Nxc6 bxc6 6. e5 Qe7 7. Qe2 Nd5 {
[pgndiagram] The starting point of the so called Mieses variation of the
Scotch defence. Here So is the first to deviate from main theoretical paths} 8.
Nd2 {Transposing back to the 8 c4 Nb6 variation. So repeats his game against
Aronian. I remember watching Peter Svidler playing blitz on internet and
saying that this is certainly not the most challenging for Black, but it can
be tricky to handle over the board. In his annotations to the Aronian game So
says the same: "Maybe White has nothing here as well but I thought it's a
better try than 9 c4"} (8. c4 {Is the mainline and by far the most popular move
}) 8... a5 $5 {[pgndiagram] And Mamedyarov is the one to surprise So instead.
This move anticipates the future b3 by White and introduces possibilites of
Ba6, which must have crossed So's mind} (8... Rb8 {Was Aronian's choice}) (8...
g6 {Is the main move}) 9. c4 {Natural and probably the best} (9. Nf3 {A
logical continuaion of knight development leads to problems} Qb4+ 10. Nd2 Ba6 {
Is awkward for White}) 9... Nb6 {Transposing back to the 8 c4 Nb6 variation.
So repeats his game against Aronian. I remember watching Peter Svidler playing

to the Aronian game So says the same: "Maybe White has nothing here as well
but I thought it's a better try than 9 c4"} 10. b3 $6 {[pgndiagram] But I
think White should have refrained from this move, since it only justifies the
early a5 more} (10. Qe4 {The typical Scotch move is probably OK for White} d5
11. exd6 cxd6 12. Bd3) (10. Qe3 $5 {Is interesting, not running into d5} d6 11.
Nf3) (10. g3 {Was also played by some strong players here}) 10... a4 11. Bb2
axb3 12. axb3 Rxa1+ 13. Bxa1 Qa3 $5 {[pgndiagram] Black already has equalized.
His queen is annoying, White's queenside is weak and he is still not fully
developed} 14. Qd1 {The best, opening the path for the bishop on f1} Bb4 15.
Bd3 Qa5 $5 {[pgndiagram] Preventing White's castling. The pin is very annoying}
16. Ke2 $5 {A brave decision by Wesley and a move that not many of us would
think of.} (16. Bd4 {Is quite human, trying o place the bishop on e3. But the
problem is that it hangs the e5 pawn} Bc3 17. Be3 Qxe5 18. O-O O-O {And
although White probably has enough compensation, a pawn is a pawn}) 16... d6 $1
{Immediately getting rid of the White's pawn and taking advantage of the king
in the centre} (16... Bc3 {Now accomplishes nothing} 17. Nf3) 17. Qc2 {
[pgndiagram] Sacrificing a pawn, but thinking about the h7 pawn and
discouraging castling} (17. exd6 {Is too greedy} O-O 18. dxc7 Re8+ {And Black
wins}) 17... dxe5 (17... O-O $2 {Is bad} 18. Bxh7+ Kh8 19. Nf3 $1 {Not being
concerned with the bishop} g6 20. Bxg6 fxg6 21. e6+ Kh7 22. Qb2 {And White wins
}) 18. Bb2 Qc5 {[pgndiagram] Removing the queen from potential rook attack on
a1 and defending the h7 indirectly} (18... g6 19. h4 {Is not that clear}) 19.
Nf3 (19. Bxh7 {Would be a gross error} Bxd2 {And Black wins}) 19... Bg4 {Still
refraining from g6, but allowing the h7 pawn to fall} (19... g6 {Was possible
now, with the knight on f3} 20. h4 Bg4 21. h5 Rg8 22. Kf1 Bxf3 23. gxf3 Nd7 {
And once again, a pawn is a pawn, although it is not THAT comfortable one}) 20.
Bxh7 Nd7 21. Bf5 {[pgndiagram] Now White is probably even slightly better}
Bxf3+ {The better choice} (21... Bxf5 22. Qxf5 g6 23. Qg4 {And although White
has a king on e2, Black is unable to exploit it, and White's pieces are well
coordinated}) 22. Kxf3 $1 {How often do you see a king on f3 with the heavy
pieces still on} (22. gxf3 {There is no reason for White to spoil his pawn
structure} Nf6 23. Kf1 O-O) 22... g6 23. Bxd7+ $1 {[pgndiagram] Good judgement}
(23. Bd3 {Would allow a nice sacrifice} e4+ 24. Bxe4 Qh5+ 25. g4 (25. Kg3 Bd6+
26. f4 Qh4+ 27. Kf3 Qxf4+ 28. Ke2 {Is also unpleasant}) 25... Qh3+ 26. Ke2 O-O
{And although the engine says this is equal, it is highly unpleasant to play
with White}) 23... Kxd7 24. Qe4 (24. Qe2 {Now allowing the f5 tempo, was
probably better} Re8 25. g3 e4+ 26. Kg2 f5 {And now White has a nice tempo he
can use to practically force a win} 27. Bd4 $1 Qxd4 28. Rd1 c5 29. Rxd4+ cxd4
30. Qa2 {And with the queen on open file this is a won position now}) 24... Re8
25. Ke2 {[pgndiagram]} (25. g3 {With the idea of taking cover on g2, made some
sense} f5 26. Qe2 e4+ 27. Kg2 Ra8 {And Black has gained time to put his rook
on the open file compared to the variation before} 28. Bd4 Qxd4 29. Rd1 c5 {IS
now a different story}) 25... Kc8 26. Rd1 f5 27. Qh4 Qe7 28. Qg3 {[pgndiagram]
Not sure if playing for a win or missjudging the endgame} (28. Qxe7 {Would
probably lead to a draw} Bxe7 29. Bc3 e4 30. h3 {And I don't see how Black can
win this}) 28... g5 {With the limited time, it is not easy to play this
position} 29. Bc3 $1 {Wesley keeps making some good moves} (29. Kf1 {Is such a
natural move} e4 {But here it is already hard to say what White should play.
Rd8 is being threatened} 30. Qe3 $1 Bc5 (30... Rd8 31. Rxd8+ Qxd8 32. Qd4 Qd6
33. Qxd6 cxd6 34. h3 Kd7) 31. Bf6 $1 {White has to see this in advance in
order to assure equality}) 29... Bc5 (29... f4 {Fails tactically} 30. Bxb4 Qxb4
31. Qxg5 Qxb3 32. Qf5+ Kb7 33. Rb1 {And White wins}) (29... Bxc3 30. Qxc3 Kb7 {
Is equal}) 30. Bd2 $2 {[pgndiagram] Probably a mistake} (30. Ra1 {Was a way to
go} Kb7 31. b4 $1 Bd4 (31... Bxb4 32. Rb1 c5 33. Qf3+ c6 34. Qxf5 {Is
excellent for White}) 32. Qd3 {With equality}) 30... f4 31. Qh3+ Kb7 $2 {
[pgndiagram] This is probably a mistake,} (31... Kb8 {IT is amazing, but
computer notes that this king retreat is much stronger, because in some
variations the king is not checked on b8 as it is on b7} 32. b4 Bd4 33. Qd3 g4
34. b5 f3+ 35. gxf3 gxf3+ 36. Qxf3 {If the king was on b7, White would be
better, but here Black can simply play} Rf8 {And he wins}) 32. b4 Bd4 33. Qd3
Rd8 {[pgndiagram]} (33... g4 {The variation examined previously now doesn't
work} 34. b5 f3+ 35. gxf3 gxf3+ 36. Qxf3 Rf8 37. bxc6+ {And suddenly it is
white who wins}) 34. b5 $6 (34. f3 {Not fearing the discovered attack on the
queen, was probably the best, although it creates additional line of attack} g4
35. b5 Qe6 36. bxc6+ Kc8 37. c5 {And White can probably survive this}) 34...
Qe6 $6 {[pgndiagram]} (34... cxb5 {Was the best move,a lthough it is highly
counterintutitive} 35. Qe4+ (35. cxb5 e4) 35... Ka7 36. Qc6 Qd7 37. Qxd7 Rxd7
38. cxb5 Kb6 {And Black retains serious chances in an endgame}) 35. bxc6+ {Now
the game should probably end in a draw, but this is not the end of shocks} Kxc6
36. f3 Rb8 37. Be1 g4 38. Rd2 gxf3+ {[pgndiagram] Just one move before the
time control, So tilts and engulfs in a hara-kiri.} 39. Qxf3+ $4 {Just
throwing the game away in one move. So was in serious time trouble here.} (39.
gxf3 {There was nothing wrong with this.} Qh3 {I imagine this was the move
that unnerved So} 40. Bf2 $1 {He just had to calculate a few steps further. I
mean "just"} Qxh2 41. Qe4+) 39... e4 {And suddenly Black has all kind of
threats. The computer announces mate in 10. Wesley resigned here, because
there is no way of defending the c4 pawn} 40. Qa3 Qxc4+ {A fascinating clash
with very unfortunate end for Wesley} 0-1

1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. e3 Bf5 5. Nc3 e6 6. Nh4 Bg6 {[pgndiagram] This
is a theoretical position. Black gives up his bishop pair in order to have a
fluid development. Topalov must be very familiar with this line since he
played it back in the 2006 World Championship match} 7. Nxg6 {The most common
move. White can't delay this move for many moves anyway} (7. Qb3 {Has also
been played} Qc7 8. h3 Nbd7 9. Nxg6 (9. Be2 {Is not ideal} dxc4 10. Bxc4 Bh5
11. g4 Bg6) 9... hxg6) 7... hxg6 8. Bd3 (8. Rb1 {Was tried by Nakamura during
the last Candidates tournament}) (8. Bd2 {Is the mainline here}) 8... c5 $5 {
And with this move we are already approaching some very rare waters. Topalov
surely takes some risk, as he will be left with an isolated pawn} (8... dxc4 {
Is a typical reaction to development of the light squared bishop} 9. Bxc4 Nbd7
10. h3 Qc7 11. Bd2 {With minimal advantage for White}) 9. Qb3 $5 {[pgndiagram]
The good move order} (9. cxd5 {Would allow extra option for Black} Nxd5 10. Qb3
Nb6) 9... Qd7 {Black has to defend on b7} 10. cxd5 exd5 (10... Nxd5 {Is now
much worse} 11. Nxd5 Qxd5 (11... exd5 12. dxc5 Bxc5 13. O-O {Favours White})
12. Qxd5 exd5 13. dxc5 Bxc5 14. Bd2 {And again White has a better IQP position
than in the game}) 11. dxc5 Nc6 $5 {Energetic move typical for Topalov.} (11...
Bxc5 {Would allow the queen exchange} 12. Qb5 Bd6 13. Qxd7+ Nbxd7 14. Nb5 Bb8
15. Bd2 {Is around equal though, but White can play this position forever}) 12.
Bd2 (12. Na4 {The main question is, what happens if White tried to hold the
pawn} Ne4 13. Bd2 $5 (13. Bxe4 dxe4 {Gives black compensation} 14. Bd2 Ne5)
13... Nxd2 (13... Nxc5 14. Nxc5 Bxc5 15. O-O {Is now excellent for White}) 14.
Kxd2 {And in this slightly irrational position, computer indicates the strng}
Rh4 {With the threat of c4 and Black has compensation for the pawn}) 12... Bxc5
{[pgndiagram] However, even in this scenario, White has a decent position
against isolated pawn} 13. Rc1 $6 {I don't like this move, allowing the
immediate d4} (13. Ne2 d4 14. e4) 13... Rd8 (13... d4 14. Ne4 dxe3 {And White
should probably go for a draw} 15. Nxc5 exd2+ 16. Kxd2 Qd6 17. Rhe1+ Kf8 18.
Nxb7 Qd7 19. Nc5) 14. Na4 $5 {[pgndiagram] A good move, trying to get the
knight on c5 and getting rid of the dark squared bishop} (14. Ne2 Bb6 15. h3 d4
16. e4) 14... Bd6 15. Nc5 Bxc5 16. Rxc5 {[pgndiagram] The critical moment of
the opening phase of the game} d4 $2 {I think that this is premature} (16... g5
{There was no need to force matters. Black could have tried improving his
position} 17. Rc2 Kf8 18. O-O Ng4 19. h3 Nge5 {And White is only slightly
better}) 17. Bb5 $2 {Returning the favour} (17. e4 {Was very strong} O-O (17...
Ng4 18. h3 Nge5 19. Bb5 Qe7 20. Bb4 {And Black is in trouble}) 18. O-O Rfe8 19.
f3 {Is excellent for White}) 17... O-O $1 {Now Black's central breakthrough is
justified} 18. Bxc6 (18. e4 {Is no longer a possibility} Nxe4) 18... bxc6 {
[pgndiagram] Now Black has strong initiative. White's king has trouble in the
centre} 19. f3 {Preventing Ne4} (19. O-O {Castling is not possible due to} Ne4)

{Looks scary, but was lesser evil} 21. O-O dxe3 22. Bb4 {And White can try to
resist}) 20... Nd5 {[pgndiagram] This move allows White back in the game} (
20... Rfe8 {Was probably even stronger} 21. O-O (21. Kf2 dxe3+ 22. Bxe3 Qe5)

e4 f5 22. Rxc6 fxe4 23. O-O e3 24. Ba5 {And it is hard to believe that White
can hold these monster pawns}) 21... Rb8 22. Qa3 Rxb2 $3 {Two exclamation
marks are for creativity, although it is not certain if this is the best move}
(22... dxe3+ 23. Bxe3 Qh4+ 24. g3 Qh3 {And White is very uncomfortable}) 23.

White can do.}) 23... dxe3+ 24. Bxe3 Qxe3+ {[pgndiagram] Black has given up
the exchange and has only one pawn in return, but the position of White's king
gives him more than enough compensation} 25. Kg3 $2 {The loosing move. It is
quite natural to remove the king out of the rook's way, but still..} (25. Kf1 {
And nothing immediately terrible for Whit is apparent} Nf4 26. Qc1 Qe5 27. Qb2

exd4 9. Nxd4 {[pgndiagram] After unpretentious start, the game transposed to
the fianchetto variation of the King's Indian defence} Re8 {The main move
nowadays.} (9... Nc5 {Also has relatively healthy reputation}) 10. b3 a6 {I
think that player in the past approached this position differently, and went
for the a5-Nc5 plan on some occasions, but not a6. However, modern theory
suggest the a6-Rb8-b5 plan often in various King's indian positions} 11. Be3
Rb8 12. a4 {The position is relatively fresh on the highest level. A previous
encounter between Maxim Rodstein and Adhiban Baskaran saw the move f3 instead}
(12. f3 Ne5 13. a4 Bd7 {And Black won that encounter, although not as a result
of the opening}) (12. h3 {Preventing Ng4 also has some logic}) 12... a5 (12...
Ne5 13. f3 {Would transpose to the afore mentioned game}) 13. Ndb5 b6 14. Qc2 {
[pgndiagram] I think that White can be content with the opening. He has more
space, although his dark squares are somewhat weak (c5 in particular)} Nc5 (

Qe7 17. Rfe1 Rbd8 {[pgndiagram] Both sides complete the mobilisation. Black's
active ideas include c6 immediately, and than possibly d5. White's plan
consists of advancing the kingside phalanx and combining that with pressure in
the centre.} 18. Bf2 (18. Nd5 {Is quite logical} Nxd5 19. cxd5 {And now it is
doubtful whether Black should decide on c6} c6 (19... Bc8 {Is the alternative}

in previously examined variation with f4} Bxh4 23. Qxh4 Ne6 {Is the key
difference. There is also no rook life to h3}) 22... Na6 23. Na2 {[pgndiagram]
Preventing Nb4} Ndc5 24. f4 Qe7 25. g5 Bg7 26. h4 f6 {This move, playing on
the side where opponent is strong would never occur to me. But Black takes
measures against being strangulated} (26... Nc7 {For instance} 27. f5 {Is very
strong}) 27. gxf6 {[pgndiagram] Probably it was better to avoid this exhange} (

1. e4 {[pgndiagram] Recently, Kramnik has played this move quite often. I

Ovo što je Karjakin danas učinio Topalovu je bilo ružno za gledati:

1. e4 c6 2. d4 d5 3. e5 c5 $5 {[pgndiagram] Far more common is the bishop move,
but this move, placing immediate pressure on White's center and leading to
French-like positions, is quite playable} (3... Bf5 {Is the main line}) 4. dxc5
{Obviously there is a lot of theory on this variation. Some grandmasters
prefered not taking the pawn on c5, but I think it is the most principled
continuation} e6 (4... Nc6 {Is another alternative}) 5. a3 $5 {This has been
played in all 2600+ encounters in the recent years.} (5. Qg4 {Has dissapeared
due to} h5) (5. Be3 {Is another alternative, with plenty of theory}) 5... Bxc5
{[pgndiagram] This move was seen only in the game Morozevich - Popov, Moscow,
2014} (5... Nc6 {Might be more precise, preventing the Qg4 resource, since} 6.
b4 a5 7. b5 Nxe5 8. Bb2 f6 {Is in Black's favour}) 6. Nf3 (6. Qg4 $5 {Is more
interesting} Ne7 (6... Bf8 {Popov chose this move, but it is rather ugly}) 7.

only to a draw} Ng6 8. Nf3 Bf8 9. Qf6 Be7)) 6... Ne7 7. Bd3 Ng6 8. O-O Nc6 9.

amazing 84% from this position} Nf4 $6 {The third move by the knight already
and the first really dubious move} (10... a6 $5 {Preventing b5} 11. c4 Bc7 {
Pressuring e5} 12. Bxg6 {The only try for an advantage} (12. Qe2 Nf4) (12. Re1

can't probably avoid making this move} (12... O-O 13. Nc3 Ne7 14. Rfd1 {Forces
him to capture on c4 all the same}) 13. Qxc4 Ne7 {[pgndiagram] Black is
neglecting the development, but castling is very risky.} (13... O-O 14. Nbd2 $1

consideration}) 15. Qg4 {And with the Ne4-Nf6 looming, Black's position is
uncomfortable}) 14. Nc3 Bd7 15. Qg4 Bc6 {[pgndiagram] Topalov tries to create
some counterplay} (15... Kf8 {Was the alternative, with inferior but tenable
position}) 16. Rad1 (16. b5 {Came into consideration} Bxf3 {Else g7 falls} 17.

counterplay})) 16... Qc7 17. Ng5 $5 {[pgndiagram] Very imaginative move} (17.

bishop support} a6 18. Ng5 {And now} Qxe5 {Loses immediately} 19. Nd5 Qxb2 20.

And Black has an unpleasant position, but it is not over}) 18. b5 $1 {
[pgndiagram] A key move in the combination} (18. Rfe1 {Is plain bad here} h5

over}) 19. Qh4 Bxb5 $2 {But this loses immediately} (19... Ng6 {Was more
resilient, forcing a queen exchange} 20. Qg3 Qxg3 21. hxg3 Bd7 22. Nce4 {And
White has a very pleasant endgame} f6 23. Bxf6 gxf6 24. Nxf6+ Ke7 25. Nxd7) 20.
Rfe1 $1 {[pgndiagram] This game is very instructive, because it shows how tiny
changes in position can change the evaluation of tactical variations} (20. Nxb5

tells everything about Black's position}) 22. Bxg7 $1 Nf5 23. Nxe6 $3 {
[pgndiagram] A great sacrifice. The game is over} (23. Qf4 {Was more prosaic})

also winning, although it would complicate things somewhat} Rf8 28. Qe5 Ng7+

former world champion by the Ukrainian.} 1-0

Mislim da će Eljanov dugo žaliti za ovim turnirom. Nakon 2/2 starta prvo ga je izswindlao Mamedyarov, a sinoć i Topalov.
Šteta jer realno prikazuje odličnu igru. S druge strane, svaka čast Topalovu na odličnoj obrani i obojici igrača veliko hvala jer su nam priuštili fantastičnu partiju punu zanimljivih varijanata:

[Event "Vugar Gashimov Mem 2017"]
[Site "Shamkir AZE"]
[Date "2017.04.27"]
[Round "6.2"]
[White "Topalov, Veselin"]

[BlackElo "2751"]
[PlyCount "119"]
[EventDate "2017.04.21"]

1. d4 Nf6 2. c4 e6 3. Nf3 {[pgndiagram] It seems like most top level players
avoid the Nimzo-Indian these days} b6 4. g3 Bb7 5. Bg2 Be7 6. Nc3 Ne4 $5 {The
main move in the position} (6... O-O {Loses control over e4 and leads to
different pawn structure, since Black is forced to go d5} 7. Qc2 d5 {The most
logical} (7... Na6 {Is inferior} 8. e4 d5 9. cxd5 exd5 10. e5 {With advantage
to White}) 8. cxd5 Nxd5 9. Nxd5) 7. Bd2 {Slightly counterintuitive, but this
was played already by Viktor Korchnoi back in 1971} (7. Qc2 {Does nothing to
win control over e4} Nxc3 8. Qxc3 O-O 9. O-O c5 10. Rd1 d6 {And Black is
pretty solid}) 7... Bf6 {Also very old, stemming back to 1974 Karpov -
Kortschnoj Candidates final} (7... Nxd2 8. Qxd2 O-O 9. e4 {Is good for White})
(7... Nxc3 {Also justifies White's idea} 8. Bxc3 O-O 9. d5 $1 {[pgndiagram]
This is the difference. With the queen on d1, White can push d5 and choke the
bishop on b7}) (7... O-O {Leads to another line} 8. O-O d5 9. cxd5 exd5 10. Rc1
{And I am not familiar with the evaluation of the opening theory here, but I
guess that White has a slight advantage. Certainly both seventh moves are
playable}) 8. Qc2 {[pgndiagram] Relatively rare move, although Topalov has
already played it against Grischuk.} (8. O-O {Was Kortschnoj's choice in the
23rd game of that match.}) (8. Rc1 {Leads to complications that aren't
unfavourable for Black} Bxd4 9. Nxd4 Nxc3 10. Bxb7 Nxd1 11. Rxd1 c6 (11... Na6
12. Bxa6 O-O 13. O-O) (11... O-O {Might be even better})) 8... Nxd2 {Black is
forced to take here} 9. Qxd2 {White loses a tempo, but is ready for e4 now} d6
10. h4 $5 {A novelty by Topalov. He makes a move useful in many variations
before embarking ona definite plan. The ball is in Black's court, so to speak}
(10. d5 {Was seen previously.} O-O (10... e5 11. h4 {Happened in practice in
the game Browne - Saidy, Reno, 1994}) 11. Nd4 {And here Black has several good
continuations} e5 (11... Bxd4 {Exchanging the bishop, is also possible} 12.
Qxd4 e5 13. Qd2 f5) 12. Nf5 Nd7 13. h4 Bc8 {And the position is balanced}) (10.
O-O {Was also played on the highest level in a game between World Champions.}
O-O 11. e4 Nd7 12. Rad1 g6 13. h4 Qe7 {And after a6-c5 Black reached a
pleasant hedgehog, and the game was drawn in the end, Anand - Carlsen, Sao
Paulo/Bilbao/2012}) 10... Nd7 (10... O-O {Probably transposes to the game}) 11.
Rd1 O-O 12. Qc2 {[pgndiagram] To be completely honest, I don't quite
understand why White delays castling that much and moves his queen instead.
Sure, there are potential Ng5 ideas, but still} (12. e4 e5 {is an equalizer,
as there is no e3} 13. dxe5 Nxe5 14. Nxe5 Bxe5) (12. O-O {Seems flexible
enough. But I guess White wanted to keep the option of the kingside attack
possible}) 12... c6 {Preventing Ng5} (12... Re8 {Was another way of doing so}
13. Ng5 $4 {Now simply loses} Bxg2 14. Qxh7+ Kf8) (12... c5 {Loses to} 13. Ng5
g6 14. Bxb7) 13. e4 Qc7 {Black is cramped for the moment, but he will soon
play e5, and he has two bishops. I don't quite like White's opening experiment
tbh} 14. Ng5 e5 {e5 had to be prevented} (14... g6 {Was also possible.
Although White has provoked a slight weakening, it is not certain whether he
can exploit it} 15. O-O a6 16. d5 cxd5 17. cxd5 e5 18. Rc1 Qd8 {And Black is
fine}) 15. d5 h6 {[pgndiagram] Chasing the knight when he wants to move anyway}
(15... a6 {Was very interesting, with the idea of b5} 16. dxc6 (16. O-O b5 {Is
good for Black}) 16... Qxc6 17. O-O b5 $1 {Nevertheless} (17... Qxc4 18. Rxd6 {
Is not ideal}) 18. cxb5 (18. Nd5 Qxc4 19. Qxc4 bxc4 20. Ne3 (20. Nxf6+ Nxf6 21.
Rxd6 {And without the knight on f3, the pawn on e5 is not under threat, and
Black gains an important tempo})) 18... axb5 19. Qd2 Nc5 {And I like Black's
active position}) 16. Nf3 a6 17. dxc6 Qxc6 18. Bf1 $2 {[pgndiagram] After
going over the game briefly for the first time, I thought that it is amazing
that Topalov still fights for advantage after delaying castling for that long.
But after this move, his position starts going downhill} (18. O-O {In analogy
with previously examined variation, was correct} b5 19. Nd5 {Now this brings
White an advantage} Qxc4 20. Qxc4 bxc4 21. Nxf6+ Nxf6 22. Rxd6 {And now Black
should probably swap the e4 and e5 pawns} Nxe4 23. Rb6 Bd5 24. Nxe5 {With
better endgame for White}) 18... Rfc8 $6 {Returning a favour, but only because
computers exist} (18... Nc5 {ACtivating the knight and attacking e4, was better
} 19. g4 {Now doesn't work} Bd8 20. g5 f5 $1 {[pgndiagram] With the rook on f8,
this move really hurts White}) 19. a4 $6 {This creates another weakness} (19.
g4 {Was very strong now} Bd8 20. g5 h5 21. Bh3 {And Black's pieces on the
queenside are rather clumsy}) 19... Nc5 20. Nd2 Ne6 21. Qb1 {[pgndiagram]
White's position is really ugly now} Nd4 22. Bh3 Rf8 23. Rc1 $6 {Refusing to
castle and losing another tempo to prevent b5} (23. O-O b5 24. axb5 axb5 25.
cxb5 Nxb5 26. Nd5 Nd4 27. Bg2 {Was nevertheless better, with chances of
resisting}) 23... Bd8 {A good move. The bishop makes way for the f5-f4 advance,
which will really hurt white due to the early h4} (23... b5 {Was still playable
} 24. cxb5 axb5 25. Nxb5 Qa6 26. Nxd4 exd4 {With great compensation for the
pawn}) 24. O-O {[pgndiagram] Finally deciding to castle, but now this is
fraught with danger} f5 $1 {Logical continuation of the plan} 25. Kh2 f4 $1 {
Now Black's position really looks threatening} 26. Qd3 (26. g4 Bxh4) 26... Kh8
$6 {I am not entirely certain why Eljanov moved his king. Whether there was a
concrete variation, or more on general grounds, in accordion with the "Don't
hurry" principle} (26... Bc8 {Exchanging the bishop defending the king, was
even better} 27. Bxc8 Qxc8 28. Ne2 Nxe2 29. Qxe2 Ra7 $1 {A common maneovre of
the rook} 30. Rc3 (30. c5 {Is maybe what bothered him, but I don't see what it
has to do with the king position} bxc5 31. Nc4 Qe6) 30... Raf7 {And Black is
much better}) 27. b3 (27. Nd5 {Was probably more resilient} Qxa4 28. Nxf4 exf4

better late then never.} 28. Bxc8 Qxc8 29. Ne2 Nxe2 30. Qxe2 Ra7 31. Rc3 (31.
c5 bxc5 32. Nc4 Qe6 {And again Black is better}) 31... b5 $1 {[pgndiagram]
Great play over the whole board, creating weaknesses on c4 and a4} 32. Rd3 (32.
axb5 axb5 {Opens another front as Black rook can now penetrate on the a-file})
32... bxa4 33. bxa4 Raf7 $1 {[pgndiagram] Taking the bold route and
sacrificing the d6 pawn} (33... Qe6 {Was perfectly possible and slightly more
pragmatic. It is hard for White to make a move} 34. g4 Bxh4) 34. Rxd6 {Now
White at least has some weaknesses to play against on e5 and a6 if he survives
the onslaught.} Bxh4 $1 {Of course, this sacrifice can't be accepted, but
Black has to find the follow through} 35. Rd5 $1 {Topalov defends very
resilliently from this point onwards} (35. gxh4 f3 36. Qe3 Rf4 {Is of course,
game over soon}) 35... f3 $4 {And this move, releasing the tension is wrong
and it is not clear whether Black is better anymore} (35... Bd8 {Slow play,
improving the position, was in order} 36. Rxe5 Bb6 37. Nf3 (37. c5 {Is better}

still holds}) 37... Qg4 {And Black has a decisive attack}) 36. Qd3 Qg4 37. Rh1

also White can use the same theme as in the game} 38. Rh1 {And everything is
covered}) 37... Bg5 38. c5 {[pgndiagram] Now Black has to be precise in order
to mantain the balance} (38. Rxe5 {Would transpose to the previous note}) 38...
Rb8 $2 {Overstepping the mark. Black still plays for attack, that is now
nonexistent} (38... Bxd2 {It was time to admit that the win is gone. But
psychologically it is really hard to adjust} 39. Qxd2 Qxe4 40. Re1 Qxa4 41.

Rxb6 $2 {[pgndiagram] And this is officialy desperation. Now Black is suddenly
lost} 41. cxb6 Rxb6 42. Rxe5 {The remainder of the game doesn't require
further comments} Bh4 43. Qc3 Rg6 44. Qe1 Bg5 45. Rf5 Rd6 46. Rf8+ Kh7 47. e5

Rc4+ {A tenacious defence by Topalov and a great pity for Eljanov who fails to
convert another good position after failing to beat Mamedyarov in the previous
rounds.} 1-0

Fantastična Wojtaszekova priprema iz osmog kola:

1. Nf3 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. Qb3 Nb6 6. d4 Bg7 {[pgndiagram]
I am not sure whether to classify the opening as an Anti Grünfeld or Grünfled,
since this position can arise from both 1 c4 and 1 d4. But I guess it doesn't
really matter anyway} 7. e4 $5 {And this move is already not the move played
most often} (7. Bf4 Be6 8. Qa3 {Is what consistutes a main line. White keeps
the option of solidifying the centre with e3} Nc6 9. e3 O-O 10. Rc1 {With some
advantage}) 7... Bg4 {Logical. Black plays against the d4 point} 8. Bb5+ {
[pgndiagram] Entering a theoretical discussion. The point of this check is to
induce the pawn on c6, instead of a knight} (8. d5 {Is double edged, as it
gives Black the possibility of undermining the centre with either c6 or e6} O-O
9. Be2 c6) (8. Ng5 O-O 9. Be2 Bxe2 10. Nxe2 Nc6 {This is the point of the
bishop check. On c6 Black's knight is much more active}) (8. a4 {Is inferior
line} Bxf3 9. gxf3 Nc6 (9... Bxd4 10. a5 {Loses}) 10. d5 Nd4 11. Qd1 e5 {And
Black has a good position}) 8... c6 9. Ng5 O-O 10. Be2 Bxe2 11. Nxe2 {
Everything here was played before. This is a risky line for White because he
delays his development and violates basic opening principles. However, modern
chess is much more concrete than that} Na6 (11... h6 {Actually there is no
point of playing this move when the queen is not on h3} 12. Nf3 N8d7 13. Be3)
12. Qh3 {[pgndiagram] Fighting for an opening advantage} (12. Be3 Qd6 {With
the idea of Qb4} 13. O-O Qb4 {And Black has fully equalized}) 12... h6 $1 {Now
this move cuts the queen off} 13. Nf3 h5 (13... Qd7 $5 {Was worth considering}
14. Qh4 h5 {The threat is Qg4} 15. O-O {And with White giving up on attack,
Black should be fine} (15. Rg1 Qg4 {Is plain bad for White})) 14. Rg1 {Now
this is very dangerous} Nb4 $2 {[pgndiagram] Amazingly, but it would appear
that this natural move is the decisive mistake} (14... Nd7 {Was played twice
by GM Emil Sutovsky and it would appear that this is the correct defence.
Black heads for f6} 15. e5 (15. g4 {Is inferior} hxg4 16. Rxg4 Nf6 17. Rh4 Qc8)
15... Nb4 16. g4 Nc2+ 17. Kf1 Nxe5 18. Nxe5 Bxe5 19. gxh5 Qc8 20. Rg4 Qf5 21.
dxe5 Rad8 22. hxg6 {[pgndiagram] And Black probably can draw this with correct
defence. It is another matter of finding it over the board. Note how White's
whole queenside is not developed. So much for the opening principles for you.}
fxg6 (22... Rd1+ {Sutovsky played this move and lost, Cheparinov - Sutovsky,
Poikovsky 2013}) 23. Nf4 Rd1+ 24. Ke2 Re1+ {Leads to a draw} 25. Kd2 Rd8+ 26.
Kc3 Nxa1 27. Rxg6+ Qxg6 28. Nxg6 Rxc1+ 29. Kb4 Rd4+ 30. Ka3 Nc2+ 31. Kb3 Na1+ {
I couldn't force myself to shorten this beautiful computer line}) 15. g4 Qd7
16. Qh4 $1 {[pgndiagram] This is the idea of GM Gajewski. Very strong} Nc2+ {
Once you said A you have to say B..} (16... Bf6 {Is a line that should be
analyzed, but it seems that Black is lost all the same} 17. Bg5 Nc2+ (17...
Bxg5 18. Qxg5 {Is dangerous}) 18. Kf1 Bxg5 (18... hxg4 19. Rxg4 Nxa1 20. Bxf6
exf6 21. Ng3) 19. Qxg5 {And it is all over}) (16... hxg4 {Was played earlier
and Black got crushed} 17. Rxg4 Rfd8 18. Kf1 {Lupulesku - Nedilko, Legnica 2013
}) 17. Kf1 Nxd4 (17... Nxa1 {Is losing and I think you can very much rely to
your intuition here.} 18. gxh5 {And Black must get crushed}) (17... Bf6 {
Doesn't help; White has multiple tactical possibilities in every direction} 18.
Bg5 Nxa1 19. gxh5 Bg7 20. h6 Bf6 21. h7+ Kh8 22. Bxf6+ {[pgndiagram]} exf6 23.
Qxf6+ Kxh7 24. Ng5+ Kg8 25. Ne6 {[pgndiagram] And wins} Qxe6 26. Rxg6+ fxg6 27.
Qxe6+) 18. Nexd4 Bxd4 19. gxh5 Bf6 20. Bg5 Bxb2 21. Re1 {[pgndiagram] Now
White simply has an overwhelming position. Check the difference in activity of
the pieces} Qd3+ 22. Kg2 f6 23. Bh6 g5 24. Nxg5 {[pgndiagram] "In such a
position, sacrifices are as natural as baby's smile"} Rf7 (24... fxg5 25. Qxg5+
Kh8 26. Bxf8 {Is game over}) (24... Kh8 {Was slightly more resilient} 25. Bxf8
Rxf8 {And now there is only one move to win} 26. Qh3 (26. Nf3 $4 {[pgndiagram]
It is never too late to lose a game of chess} Rg8+ 27. Kh3 Qxf3+ 28. Rg3)) 25.
Nxf7 Kxf7 {Now White has the material advantage that adds up to his attacking
position} 26. Re3 Qc2 27. Rg3 Bd4 28. Rg7+ Ke6 29. Qg4+ Kd6 30. Be3 Bxe3 31.
Qg3+ {A brilliant game by Wojtaszek, even if much of it was cooked at home.}
1-0

Jadan Eljanov opet gubi dobru poziciju u zadnjem kolu:

[Event "Vugar Gashimov Mem 2017"]

1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 Be7 5. Bg2 {[pgndiagram] So once again
Kramnik is forced to fight against his own favurite Catalan} O-O 6. O-O dxc4 7.
Qc2 a6 8. a4 Bd7 9. Qxc4 Bc6 10. Bf4 {[pgndiagram] So far, Eljanov repeats the
line used by Wesley So in round five} Nbd7 {And Kramnik is the first to
deviate. He continues his development instead of the move by wing pawn.
However, this move is very rare and appeared only once on the highest level.} (
10... a5 {Was his choice in game against So.}) (10... Bd6 {Is probably the
main move in this position, played in many game on the highest level}) 11. Nc3
(11. Rd1 {This was White's choice in Wojtaszek - Ivanchuk, Vladimir Petrov
memorial 2013.}) 11... Bd6 (11... Nb6 {Is a reasonable move here, going for
the d5 square. The downside is that it loses some control over e5} 12. Qb3 a5
13. Rfd1 Nbd5 14. Nxd5 Nxd5 15. Bd2 Nb4 16. Bxb4 Bxb4 17. Ne5 Bxg2 18. Kxg2 c6
{And this is slightly reminiscent of the afore - mentioned So - Kramnik game.
White is slightly better}) 12. e3 $5 {A typical Catalan move. White is not
afraid of doubled pawns; he is only interested in the e5 square} (12. Bxd6 {
Also leads to a slight edge} cxd6 13. Rfc1 Rc8 14. Qd3 Nb6 15. a5 Nbd5 {And
White is slightly better}) (12. Bg5 {Is not effective here.} h6 13. Bxf6 Nxf6 {
And White doesn't have control over e4} 14. e3 a5) 12... Nb6 (12... Bxf4 13.
gxf4 {Leads to the same} Nb6 {Black probably can't avoid this move all the same
}) 13. Qb3 Bxf4 14. gxf4 a5 {Preventing a5. Kramnik plays good chess so far
and has equalized.} (14... Nbd5 15. Ne5 {Is slightly unpleasant}) 15. Ne5 {
[pgndiagram] Occupying the e5 square, but also exchanging Black's problematic
light squared bishop for White's famous Catalan bishop. The position should be
equal.} Bxg2 16. Kxg2 Nbd5 (16... Nfd5 {Keeping the other knight on the
queenside, also comes to consideration} 17. Rg1 Nb4 18. Rac1 Re8) 17. Rg1 {
[pgndiagram] Very subtle move that I don't understand completely. White keeps
the option of attacking White's king, by some sort of Qd1-Qf3-f5 maneovre. If
Black plays g6, than there is possibility of h4-h5.   But all these ideas look
risky for White} (17. Qxb7 {The consequences of this pawn grab are not clear}
Rb8 18. Qc6 Rb6 19. Qc5 Rxb2 {With complications} 20. Nc6 Qe8 21. Nxd5 Nxd5 22.
Kh1 {And this position should be equal, but I think it is easier to play Black
in pracatical game}) (17. Rac1 {Normal play is also possible} Nb4 18. Rfd1 Nfd5
{And Black is slightly more comfortable}) 17... Rc8 {Flirting with c5} (17...
Nb4 {Just to demonstrate White's idea, I will play some natural moves by Black}
18. Kh1 Qe7 19. Qd1 c6 $6 {This is probably bad, going for c5 is much better
idea} (19... Rac8 20. Qf3 c5 $1 {And White doesn't have time to create
kingside attack}) 20. Qf3 Nfd5 21. Rg3 {And White already has some pressure on
the kingside}) 18. Rac1 {Preventing c5} Nb4 {[pgndiagram] The correct idea now,
when White can't attack on the kingside due to c5 counter} (18... c5 $2 {Would
now just drop a pawn} 19. Nxd5 Nxd5 20. Rxc5) 19. Qc4 {White choses to place
his queen on c4 in order to have both e2-g4 and b5 options available} (19. Na2
{Exchanging Black's most active piece, came into consideration} Nxa2 (19...
Nbd5 20. Nc3 {Repeats}) 20. Qxa2 c6 21. Qb3 Qc7 {Once again with the 0.0
evaluation}) (19. Qd1) 19... g6 {[pgndiagram] Preventing all ideas on the
kingside} (19... Nfd5 20. Nxd5 exd5 21. Qb5 {Is slightly unpleasant, as now
the concrete play begins} f6 (21... b6 22. Nc6 {IS horrible for Black}) 22.
Qxa5 fxe5 23. Qxb4 exf4 24. Qxb7 {And Black should be fine, but it is
completely another story}) 20. Rgd1 (20. Qb5 {Is not so dangerous with a pair
of minor pieces still on the board} b6 21. Nc6 Nxc6 22. Qxc6 Qe7 {And Nd5-Nb4
will dislodge the queen.}) 20... c6 {[pgndiagram] This game is really
instructive example of how to play in equal positions} 21. Qe2 Qe7 22. Nc4 Qc7
23. Qf3 Nbd5 24. h4 $6 {Comital. White gains space and restricts the movement
of Black f6 knight, since h5 is always a possibility. However, weakened
White's kingside will become major factor later on.} (24. Ne4 Rfd8 25. b3 {Was
more careful}) 24... Rfd8 (24... Nh5 $5 {The transfer of the knight on f5 was
a nice idea} 25. Ne4 (25. b3 {White doesn't have time for e4 in any case} Ng7
26. Ne2 Qd8 27. Rh1 Nf5 28. Qh3 h5 {[pgndiagram] And now e4 fails tactically}
29. e4 Nxd4) 25... Ng7 26. Nc5 Nf5 27. Rh1 h5) 25. b3 Nxc3 26. Rxc3 Qe7 27. Ne5
Kg7 $5 {[pgndiagram]} (27... Nh5 {Is not that attractive anymore (it is
amazing how little changes in the position change the evaluation of a certain
move)} 28. Rh1 Ng7 29. Qd1 Nf5 30. h5 {And Black is suddenly worse}) 28. Kh3 {
A consequence of an early h pawn advance} (28. Rh1 Nh5 {Stops all play on the
kingside and Black can try to create something on the queenside (b3 is a
weakness)}) 28... c5 $6 {Maybe this advance comes too early} (28... Qb4 {Came
into consideration, activating the queen on the kingside and disrupting
White's pieces} 29. Rcd3 c5 30. dxc5 Rxd3 31. Rxd3 Rxc5) 29. Rdc1 {[pgndiagram]
Now this pin is slightly unpleasant, and Black is forced to weaken his
queenside. After lengthy positional play, the game suddenly takes quite
different route} b6 30. dxc5 Rxc5 31. Rxc5 bxc5 32. Nc6 Qb7 33. Kg2 $6 {Not
the best} (33. Rxc5 {Was strong, but it has to be calculated really precisely}
Rd2 34. h5 $1 {The only move that gives the advantage. The point is that Black
knight is diverted from the e4 square if he takes on h5.} (34. Kg2 Qxb3 {
Leaves Black better}) (34. Ne5 {Immediately is met by} Ne4 {[pgndiagram] And
White is in trouble} 35. Rxa5 Rxf2) 34... Qxb3 (34... Nxh5 35. Rxa5 Rxf2 36.
Qxf2 Qxc6 {And Black has the advantage}) 35. Ne5 {And White is much better,
although this is a computer line}) 33... Rd5 34. Nxa5 Qb4 35. Nc4 Qxb3 36. a5 {
[pgndiagram] Everything was forced after 33 Kg2 up to this point} Qa2 $1 {A
good move. Black puts the a pawn under surveillance and also eyes the f2
weakness. White has to be careful} 37. Kf1 {White prepares Qe2 with this move}
Rh5 $5 {Taking the advantage of premature h4 and letting her majesty handle
the passed a-pawn} 38. Qe2 Qb3 $2 {But this is really dangerous for Black} (
38... Qa4 {Is safer} 39. Qb2 Rxh4 40. Qb7 Qa2 $1 {And here White has to find
the only move} 41. Ne5 {[pgndiagram]} Rh2 42. Qxf7+ Kh6 43. Nd3 Rh1+ 44. Kg2 {
And this position is dynamically balanced, although in practical game
everything is possible}) 39. Qc2 $2 {Missing an opportunity} (39. Qb2 {
Stopping b7 and offering queen exchange} Qd3+ 40. Kg1 Qe4 {But here White had
to foresee the crucial} 41. f3 {[pgndiagram]} Qxf3 42. Qg2 {Forcing the queen
exchange, when White should be winning in the endgame}) (39. a6 {Was also
stopping Qb7}) 39... Qb7 40. Qb2 {One move too late. I am not sure what
Eljanov missed} Qa8 $2 {Amazingly, this seems faulty} (40... Qc6 {Seems to be
better, because future Qb7 wouldn't block the Queen's path} 41. Ke2 Rxh4 42.
Rb1 Rh2 {And now} 43. Qb7 Qa4 {Is dangerous}) (40... Qf3 41. Nd2 {Leads nowhere
}) 41. Ke2 $1 {[pgndiagram] White's king is pretty safe in the centre} Rxh4 42.
Rb1 Qg2 {the culmination of the game} (42... Rh2 {Is now met by} 43. Qb7 {And
White wins}) 43. Ne5 $2 {The key moment. White switches to defensive instead
of pushing forward} (43. a6 {Was winning for White, although the winning path
is rather complicated} Rh3 {White has to be careful} 44. Rf1 $1 {The key move,
reducing the effect of Qf3-Rf1} (44. a7 $2 {Is faulty, for example} Qf3+ 45.
Kd3 {And this is not what White wants. The computer says this is equal and we
can only believe the machine. But the king on d3 really looks ugly}) 44... Qf3+
45. Ke1 {And White wins}) 43... c4 $1 {Strong play by Kramnik. This strong
pawn comes into play with devastating efect. The point is that if White takes
on c3, he will be hit with Ne4} 44. Qd4 $2 {[pgndiagram] The moment when the
tides turn} (44. Nxc4 {Was ok} Rh2 45. Rf1 Qc6 {And position is equal}) (44.
Nd7 {Would also force a draw} Rxf4 45. exf4 Qe4+ 46. Kf1 Qh1+) 44... c3 {The
pawn advances all the same and now White's position is suddenly worse} 45. a6 (
45. Rf1 {Not allowing the pawn advance to come with tempo, was more resillient}
c2 46. Qa1 Rh3 47. Rg1 $1 Qd5 48. Qb2 {And White can resist, although in
practical game it is virtually impossible}) 45... c2 46. Rc1 Rh1 47. Rxc2 $2 {
[pgndiagram] The final mistake} (47. Qa1 $5 {Would put more resistance} Rxc1
48. Qxc1 Qa8 49. Qxc2 Qxa6+ 50. Kf3 {And Black still has some work to do})
47... Qf1+ {Now the game is over. Black has a winning attack} 48. Kd2 Qd1+ 49.

breaking end to a tournament that could have been fantastic for Eljanov, but
in the end..} 0-1
