serious difficulties in reaching better squares.} d5 14. f4 b5 15. f5 {Another

important victory for the Russian grandmaster, who showed great technique and
enviable accuracy. Alekseev employed Fischer's idea 6.h3 against the Najdorf
Sicilian, and after Black made a dubious novelty 12...Nc6?!, White proceeded
to a better endgame. The rest was a textbook example of using the bishop pair.
Evgeny skillfully restricted the opponent (23.b3!) and consistently developed
the queenside attack (28.Ra1!, 35.Rb1!). Sergey didn't have a single chance!}

{Before the game I wasn't happy with how the pairings went. I had chosen the
worst possible number, and was forced to play two first rounds with Black.
Seeing, however, how this game went, I'm not so sure if my fortune was that
bad :) But ok, let's get back to the game. I think I know David quite well. We
are playing the same Wasko Katowice team in the Polish extraleague, besides we
have played some games against each other. He is a highly civil and
well-mannered person, but not in his chess games! In chess he is known for his
calculating skills, massive memory, deep opening preparation and enormous
creativity. However, in the last period of time it seems as if creativity is
playing tricks on him sometimes. David is an universal player, mainly choosing
between 1.e4 and 1.d4. Obviously I was prepared for both, but spent 10% of my
time on 1.e4 and 90% on 1.d4. Guess which move was played?} 1. e4 c5 2. Nf3 d6

different options on move 6, but this one was quite probable. My games from
the Black side weren't very convincing, besides I got a difficult position in
one of our friendly blitz games at the closing ceremony of the Polish
extraleague. I wasn't naive enough to think he would forget about this game :)}

strategic maxim indicates that it is often very sensible to meet a flank
attack by the opponent with a counterblow in the centre. The drawback of this
continuation lies in the fact that Black is slightly behind in development. On
the other hand White's pawn structure on the kingside is exposed, so
counterplay will nearly always be possible.} 8. exd5 Nxd5 9. Nde2 h5 $5 {

to achieve the g2-g4 thrust. It does not have to be only preemptive like in 6.

round started at 9 am.} Nc6 10. Be3 O-O 11. a3 $5 {I understand this looks
weird but it has a subtle point. White waits for Black to take on d4 when he
can directly take with his queen saving a tempo. 11.a3 is a useful move which
White has to play sooner or later. Black has to come up with some sort of
useful move without making any concession (...Nxd4 allowing Qxd4 in one tempo)
which is not so easy. For instance, the natural ...Qc7 allows h5 while an
immediate ...Ne5 allows f4.} Rb8 {While Loek was thinking I was also

eindrucksvoll.} 40. Rh6 Bf5 {[%csl Rh6][%cal Rf5g6]} 41. Rxh5 {Die Drohung Lg6
muЯ WeiЯ nicht undedingt bedienen, wenn er mit dem b-Freibauern schnell genug
ist. Die nun folgenden Vorschlдge und Analysen sind unbedingt zu ьberprьfen!
Nun werden Sie bei Durchsicht der Varianten einwenden, daЯ angsichts von
Abspiel b) doch nur die Partiefolge erreicht wird. Warum also das Risiko der
Turmeinsperrung eingehen? In der Partie ist die Entscheidung zu Txh5 sicher
richtig und praktisch, wir aber wollen bei der Analyse mцglichst nichts

would have remained preferrable, with practical no chances of activity for

As a Najdorf player myself, I can commiserate with the intimidating pawn storm
that Li was facing in this position. In these situations, Black needs to be
very precise, while White usually has a series of automatic moves, just
pushing pawns until Black's king is completely exposed. There is a natural
tendency for Black to lash out, hoping for counterplay before getting
checkmated. This is precisely what happened with Black's current move..
Unfortunately, Black's lashing out only worsens Li's position. Black needed to
play 21... exf4 in order to contain White's pawn storm, although Li would
still be in a difficult position.} (21... exf4 $1) 22. exd5 (22. g6 $1 {

an important diagonal. On the other hand I am not so sure about Black's
bishops. The f6-bishop is passive, and the b7 one is limited by the f3-e4
pawns. Black has a weakness on d6, but it is compensated for by White's
weakness on f3. Overall, the position is complex, but there is no doubt that

{It was the third game with Alexei in Poikovsky. Each of the two previous
encounters (in 2008 and 2009) ended in a draw, after a very sharp fight, and
there was every reason to believe that the present game would be special as
well. Actually we haven't met over the board for several years, but we did
work together at the ACP Cup, which took place in Riga in 2013. Alexei was the
co-organizer of the event, and we even commented on the final match together.
Now it was time to show that we still are active players. Well, judging from
my performance in this tournament I can't say that I was successful proving
that point, but there were a number of thrilling games played, which proves
that there was a method in the madness that I displayed in Poikovsky :)} 1. e4
c5 {Ocassionally I play 1...e5 and 1...e6 , but the Sicilian always remains my
main weapon.} 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 {Good old Najdorf. I
remember working on it in 1993-1994, when I had just started to play this
system (prior to it, I was playing the Sveshnikov almost exclusively). My
trainer back then, Lev Psakhis, was not amused about my decision to pick up
the Najdorf - "you don't even imagine, how much theory you'll have to
remember". Well, now it sounds like a good joke. Oh, rather like a bad one. As
now, the Najdorf got so HUGE...} 6. Be3 {Shirov's pet move. He was among those
who made 6.Be3 so popular in the 90s, but even one of the godfathers of this
line can't catch up with all the recent developments, and so after the
principled} Ng4 {Alexei thought for a while, and played...} 7. Bc1 Nf6 8. h3 {
A rather fresh line. Fresh...Nowadays any fresh line is analyzed so
extensively that it loses the touch of freshness after a year or two in the
best case scenario. I have played the h3-system myself - actually it has
started back in 2008, when Gata Kamsky asked me to prepare some poisonous
sideline against the Najdorf, which I duly did. Soon the ideas in this system
were exhausted, but for the 2011 candidates matches we had prepared a new
setup, which revived the h3-system and has made it popular ever since.} e6 {
Of course another option is 8...e5, which is actually a bit more popular.} 9.
g4 h6 10. Bg2 Be7 11. Be3 Nc6 {The latest trend. I had analysed this position
back in 2011 and considered it rather comfortable for Black, but strangely
enough, it remained sort of a sideline until recently.} 12. f4 ({Another
option is} 12. Qe2 {, which was tried recently by Shirov against Khismatullin.
Black has easily solved all the opening problems after} Nxd4 13. Bxd4 e5 14.
Be3 Be6) 12... Nd7 {That's the point of Black's setup. Now White has to castle
short or allow exchanges. Alexei opts for the most principled approach.} 13.
O-O (13. Qd2 Nxd4 14. Bxd4 e5 15. fxe5 Bh4+ 16. Bf2 Nxe5 17. O-O-O Bxf2 18.
Qxf2 Be6 {allowed Black to equalise comfortably in Anand-Mamedyarov 
(candidates' tournament 2014).}) 13... Nxd4 14. Qxd4 O-O {Now things slow down
a bit. Black is happy with his Scheveningen setup, because White's pawn on g4
is out of sync with short castling and positional play. In order to justify
his strategy, Shirov comes up with an interesting idea.} 15. Ne2 $5 b5 (15...
e5 {was another option that I seriously considered.} 16. Qd2 exf4 17. Nxf4 Ne5
18. b3 Be6 {looks fine for Black as} 19. c4 {is timely met by} b5 {Finally, I
opted for the game continuation, because it seemed more ambitious to me than
simplifying matters in the centre. I just did not believe that Nc3-e2-g3-h5
can be too dangerous. Well, in the aftermath, both 15...e5 and 15...b5 are
enough for equality, but not more than that.}) 16. Ng3 Bb7 17. Nh5 e5 18. Qd2 {
This position I had reached in my calculations, prior to deciding on my 15th
move. I saw that Black has several sensible options here, but when the
position arose on the board, it turned out that matters are not that simple.}
Nf6 (18... Nc5 {suggests itself, but after} 19. f5 {I'd have to stop the white
attack with the ugly-looking} f6 {Now, the funny thing is that I knew that
computers like Black in such structures. I have parried immediate threats and
White's h4-g5 plan is not easy to be implemented. Still, I was reluctant to
seal my bishop in on e7 and I finally opted for the more classical approach in
the game.}) 19. Nxf6+ Bxf6 20. g5 {White has to go forward - otherwise he will
just be slightly worse.} hxg5 (20... exf4 21. gxf6 fxe3 22. Qxe3 Re8 {was my
initial idea, when after 23.fxg7 Qg5 Black has a comfortable ending. However,
I spotted} 23. Rf5 {and didn't quite like it. Black might still be OK, but I
decided not to check it as I had another decent option.}) 21. fxg5 Be7 {
Once again, it is time to slow down. White has nice pressure on the f-file,
but that's about all he has achieved. On the other hand, Black intends to
attack White's weak pawns and also to press on the c-file.} 22. a4 $1 {A
clever one. Alexei realises that he needs to play on the queenside - not
because he is better there, but to prevent me from becoming too strong on that
wing. Let's call it prophylaxis.} Qd7 23. axb5 axb5 24. Qd3 Bc6 {Eyeing the
b5-pawn and enabling ...Qd7-b7 in some lines. Not a bad decision, but} (24...
Ra4 $1 {was a bit stronger. Now, taking on a4 is bad on general grounds as
after 25.Rxa4 bxa4 Black would increase the pressure on the queenside. So
White has to play} 25. b3 {, but this takes away the important b3-square from
the queen. Now Black can take on a1 or retreat with the rook, preserving a
slight edge. Well, I hear you saying: it is not a huge improvement compared to
the move played in the game! You are correct: in this particular game the
difference is not that significant, but the commentary is about general ideas
that can be useful under slightly different circumstances, isn't it?}) 25. Rxa8
Rxa8 26. Qb3 $1 Qe6 27. Qxe6 fxe6 28. h4 {Now White is ready for the expansion
on the kingside, so I have to strike back!} d5 29. h5 {That came as a surprise.
} ({I had considered} 29. exd5 {to be the main move. And the engines agree
with me, promising White a slight edge. Ok, now it's my turn to agree with the
home beast, although the position after} Bxd5 30. Rd1 e4 {doesn't seem to be
dangerous for Black.}) 29... d4 {An important decision. I had to decide on the
pawn formation, and it took me around 20 minutes to come up with the move in
the text, which might indeed be the best option.} 30. Bd2 g6 $1 {That's the
point. Although it allows the seemingly dangerous 31.h6, it does prevent 31.
g6!, which in fact was a real threat!} 31. h6 b4 $1 {Just in time. Now White's
pawns are fixed and he has to protect them. In fact, if Black was doing OK on
the queenside, I could have clIMWS more than equality. But you can't have it
all, can you?} 32. Kh2 Bb5 33. Rb1 (33. Rc1 Ra2 {is dangerous for White.})
33... Rc8 34. Rc1 Kh7 $6 (34... b3 $1 {was stronger but being short of time I
didn't notice that after} 35. cxb3 Rxc1 36. Bxc1 Bb4 37. Bh3 {I can simply play
} Bd3 $1 38. Bxe6+ Kh7 {and White is helpless against Bd3-c2, followed by the
pawn march. So, he has to play 37.Kg3 with a drawish line, similar to the one
that occured in the game.}) 35. Kg3 $6 (35. b3 $1 {stops b4-b3 forever and
leaves White with the slightly better position. Well, Black would have no
reason to panic as after} Ra8 (35... d3 $2 36. Bf1) 36. Kg3 Bc6 {White can't
break through. Still, Black would need to handle it with certain care.}) 35...
b3 {Now it is White who has to find only moves in order to hold the game. It
is not too difficult though, and Alexei manages it in spite being short of
time.} 36. cxb3 Rxc1 37. Bxc1 Bb4 38. Kf3 Bd3 39. Bh3 Bc2 40. Bxe6 d3 41. Ke3
Bc5+ 42. Kd2 Bb4+ 43. Ke3 Be7 44. Kf2 Bb4 {Quite a remarkable game, in my
opinion. No fireworks, but a topical theoretical discussion followed by subtle
manoeuvring, attacks and counterattacks on the kingside, on the queenside and
in the centre... That's the sort of draw you enjoy!} 1/2-1/2
