The 40th Chess Olympiad is taking place in the Turkish metropole of Istanbul,
from August 27 to September 10th, 2012. A record of 158 national chess federations
have brought teams to Istanbul to participate in this prestigious event, which
is being staged in the WOW Hotel and Convention Center, just minutes away from
the airport.
Round ten comments by GM Alejandro Ramirez
The match situation was of course, very tense. With four teams tied for first
place it seemed like anything could happen. Of course, the match-up of the day
was China-USA, which ended in a victory for the Chinese after Ding Liren managed
to convert a seemingly drawn endgame against usually super solid Alexander Onischuk.
The rest of the games were relatively uneventful draws, though you could say
that USA was slightly lucky to get the full 1.5/3 on those boards.
On the second table was a very unexpected match. Argentina is by no means
a 'weak' team. They field four GMs near 2600, but by Olympiad standards they
are nothing special. Yet somehow, after losing a match to Poland and drawing
India, they find themselves only one point behind the leaders. Since Russia
had already played the other teams with 15 points, they had to 'bring up' someone.
The match should've been somewhat easy for the top ranked team, at least in
theory. However Russia really suffered, their black pieces being held to draws
with no problems and Sandro Mareco putting on the pressure (as black!) against
Jakovenko. Unfortunately for the latin community Mareco could only draw and
Flores lost disastrously to Karjakin in a miniature. Russia prevails with their
typical 2.5-1.5 and joins the Chinese in the lead.
The last team with 15 points was Armenia, who got a strong opponent in the
Netherlands. The Dutch team started the Olympiad horribly, losing to Venezuela
(!) and Georgia in rounds 2 and 3, but they recovered and bested Israel in the
last round. However, Armenia showed them why they have been playing nothing
but the top boards the entire event.

1.d4d52.c4c63.Nf3Nf64.Qb3e65.g3Be76.Bg20-07.0-0Nbd78.Bf4a59.Rc1Nothing too interesting so far. Both players are developing like Caissa
ordained: with White having a bit more space and Black in the defensive. As
a side note Aronian used this line as White to defeat Eljanov. It seems that
Giri keeps using Aronian's lines and they backfire.h6This move is more annoying
than it looks. Sometimes White wants to develop a knight to d2 but the bishop
gets kind of trapped with g5-ng4 and stuff. The position is super closed anyways
so you can afford this.10.a4I have never claimed to be a positional genius,
but I don't like creating unnecessary holes in my position.Ne411.Nfd211.Nbd2seemed better as well.11...Nd612.Bxd612.c5?!Nf513.Nf3Nxd414.Nxd4e512...Bxd613.e4dxe414.Nxe4Bb415.c5Nf616.Qc4?!The
way Giri has been handling the position is rather strange. With no knights to
take advantage of the d6 square there will be no way to hold Black back from
eventually pushing e5 and opening the position for the pair of bishops. I like
Black already.Nxe417.Bxe4Kh8A Kasparovian move, improving the king before
going for the throat. Not that too many people imagine there is a huge attack
lurking anywhere soon.18.Bg218.Nc3e519.d5f520.Bg2e4transposes18...e519.d5f5!19...cxd520.Qxd5Qe7was also possible but the move
in the game is more energetic.20.dxc620.Nc3e421.Rd121.d6b6breaks
the pawn structure immediately and leaves Black clearly better.21...Qf620...e421.cxb7Bxb722.c6Ba6The pawn sacrifice is very strong. It's
interesting to see how strong players find all these kinds of ways to open up
the position from something that seemed quite normal. White isn't lost, but
his position is uncomfortable. The fact that he has not developed is making
a very obvious impression.23.Qb3Rc824.Nc3Rxc625.Nd5Bc526.Bf1Trying
to trade off bishops. Aronian is like 'nah'.f4!This advance is very brutal,
let's look at some sample variations:27.Nxf4This meets a pretty simple
refutation. I'm not entirely sure why Giri went for this as opposed to the slower
and more painful death. Huh maybe I do know why.27.Bxa6fxg328.hxg328.Bf1Qh429.hxg3Bxf2+30.Kg2Rg6-+and the whole house falls down.28...Bxf2+29.Kg2Rxa6-+27.Rxc5objectively best.Rxc528.Nxf4Rc628...Rxf429.gxf4Bxf130.Rxf1doesn't seem all that convincing to me.29.Bxa6Rxa6and Black remains the exchange up because White doesn't have any tricks.
This was however White's best hope. Black's e-pawn is somewhat weak, and g6
is weak, so there are chances.30.Ne6?Qb8!31.Qc4Qc8!Aronian obviously
saw this when playing f4. Dude is just so good. Now the trade is forced and
Black wins.27...Bxf2+!28.Kh128.Kxf2Rxf4+28...Qd2+??29.Kg1Rxc130.Ng6+is a no no.29.gxf4Qd2+30.Kg130.Kg3Rg6+-+30...Rxc131.Rxc1Qxc132.Qh3e3is completely kaput.28...Rb6The rook must
protect g6 so it cannot be traded. Thankfully there is this neat intermediate
move that solves that issue.29.Qc2e330.Bg2Qe8White might be alive,
but it's temporary.31.Qc5Rff6White's nearly zugzwanged, since he is completely
tied down to the e-pawn. Moves like Rab1 or b3 would've allowed him to flail
around a bit longer.32.Rc2?32.Nd5e233.Nxf6Rxf634.Qxa5Re6-+32...g533.Nd533.Ne2Bd3-+33...e234.Qxa5e1Q+34...Rbd6was
more exact but who cares.35.Rxe1Qxe1+36.Qxe1Bxe137.Nxb6Rxb638.Rc6Rxc639.Bxc6Kg740.Kg2Kf6White's down a piece, Levon's got this. The rest
is pretty simple. Such powerful play by the Armenian! Giri really had no chance
this game to create anything.41.Bf3Ke542.h4Bc843.hxg5hxg544.Kf1Bxg345.b4Kd446.a5Kc447.a6Bb848.Bb70–1
Akopian also won with black after Sokolov pushed his pawns too far in an Exchange
Slav and a timely piece sacrifice left White's pawns too weak to defend. The
ensuing endgame proved that four passed connected pawns have more potential
value than a knight. Specifically four queens more valuable. Armenia took the
match and set up a heartstopping last round. Since the top three teams already
played each other, they will be pulling up from the trailers, Ukraine at 16,
USA, Hungary, Poland and Germany at 15. Will the top teams maintain their momentum?
Who will lose the gold medal in the very last game? Sunday will be a big day.
Round ten summary
The Open Section will see an exciting finish as three teams are entering the
final round with equal points: China, Armenia and Russia (sorted according to
tie-break score).
The Chinese team with Bu Xiangzhi, Ding Liren, Wang Yue and Wang Hao
China's top striker Ding Liren nicely outplayed Alexander Onischuk in a rook
endgame, and with the other three games being drawn, China signed an important
victory against USA.
Russia assumed a quick lead against Argentina as Diego Flores lost a wandering
knight to Sergey Karjakin right from the opening. But Argentinians held two
draws with white pieces and Sandro Mareco pressed hard against Dmitry Jakovenko.
Mareco was a pawn up but he couldn't convert the advantage and the match finally
ended in Russia's favour.
Armenia achieved a relatively easy win against Netherlands. Levon Aronian won
a nice game against Anish Giri (above), while Vladimir Akopian sacrificed a
piece for three pawns and proceeded to an endgame where his phalanx was unstoppable.
Armenia won 3-1. Ukraine leaped ahead to the fourth place thanks to a narrow
2.5-1.5 victory against Azerbaijan. Czech Republic took an early lead with David
Navara's win, but then the Polish team switched the gear and won the remaining
three games.
As the leaders have already played against each other, in round 11 they are
paired against teams in the lower point groups: Ukraine-China, Hungary-Armenia
and Russia-Germany.
In the Women Section the things are heating up again as the 22nd-seed Kazakhstan
bravely drew against the leading China. WIM Guliskhan Nakhbayeva held the World
Champion Hou Yifan to a draw, while Madina Davletbayeva totally outplayed Ding
Yixin. Zhao Xue could only even up the score with a victory against Gulmira
Dauletova.
Kazakhstan vs China with Guliskhan Nakhbayeva facing Hou Yifan
Russia convincingly defeated Armenia by 3.5-0.5, as Lilit Galojan was the only
player to make a draw for her team. Russia is now even with China in the term
of match points, while China still holds some edge in the tie-break.
Poland vs Ukraine, with GM Monika Socko facing GM Kateryna Lahno on board
one
Ukraine narrowly beat Poland 2.5-1.5, with Natalia Zhukova bringing the key
point, and is now in serious contention for one of the medals.
The Peruvian teams, with the hero of the day, Deysi Estela Cori Tello, front
right
From the other matches, it should be noted that the 2011 World Junior Champion
Deysi Cori beat the top-rated player in the section, Anna Muzychuk (2606), as
Peru defeated Slovenia by 2.5-1.5.
