All the attention of the week is clearly on the nd FIDE Grand
Prix in Tashkent.
A er rounds we have quite a surprising situation:
With / , the sole leader and is not Caruana, Karjakin or
Gelfand, it is Dimitri Andreikin, who looks like he never wants
to win a single game, but with his very solid style he collects
the ”free points” that opponents give to him. The nd- rd
places are shared by Nakamura and Mamedyarov and these
two are playing both very fighting and entertaining chess.
Caruana seems to be too tired, as he has been missing good
winning chances in a couple of games already and is on %.
It is clearly a very disappointing tournament for Boris Gelfand,
who shared st place with Caruana in the previous Grand Prix.
The happiness was also very short for Vachier-Lagrave, who
started so well with / but somehow couldn’t win any more
games and even lost one.
As expected, Jobava shows very exciting chess! He got lucky
in a few games, but he has an unstoppable desire of creating
some mess on the board. He outplayed a lot of his opponents
very nicely, but the loss to Andreikin with the white pieces in
the th round is clearly a hard blow in a tournament that was
going so well.
In the last rounds we are going to see a lot of tension, as both
Nakamura and Mamedyarov need to fight for the tournament
win to be able to get into the top places and qualify for the
Candidates
.
There are a few other big events currently under way:
The World Senior Championship is held in Greece and one
of the biggest German Opens in Bad Wiesse, but without the
participation of any
rated players.

At the European Youth Championship we saw a domination of
the Russian kids.
That’s all for the current week and we can already be very
excited about the upcoming World Championship match
between the World Champion Magnus Carlsen and the
challenger Vishy Anand, which starts on the th of November
in Sochi, Russia.

Best rating:
Jobava wins a very nice attacking game with the black pieces.
.e c .Nf
Karjakin usually plays the very sharp Advance
variation against the Caro-Kann ( .d d .e ), but this time
he chooses a rather calm setup to avoid Jobava’s creativity in
the middlegame.
...d
.Nc dxe
[ ...Bg is the most common reaction.]
.Nxe
Nf
.Nxf + exf
White should have a very small,
but longterm advantage due to the better pawn structure.
.Bc
...Qe +!?
This clever check confuses the development of
the white pieces. At such an early stage of the game, White
should avoid trading queens, but then he should retreat with
his bishop to a more passive position.

.Be

Black does not waste time with his queen moves,
because it belongs to c anyway. White cannot make use of
the delaying of the development, because Bd followed by
- is coming in time.
.d
Bd
.O-O O-O .h
A useful move to avoid the
bishop’s development to g .
...Rd
I like this move a lot! Black does not decide yet,
where to develop his c bishop, he improves his other pieces
first with Nd -f and develops the bishop only a erwards,
according to White’s setup. It is not easy to asses the ideal
arrangement of the white pieces. White should first decide
whether he wants to build up his position with c or c .
Both are playable and both have their plusses and minuses.
Karjakin chooses the more agressive one with c ... [In case
of ...Bf White could head for a superior endgame with
.Bd !
Bxd
.Qxd followed by Bd and Rfe . In all
the endgames, Black will feel the drawback of his doubled
pawns, as White will be able to create a passed pawn on the
queenside, while Black cannot do the same on the kingside.]

White activates his bishop. We
can see the e ect of the . ..Qe check here. The bishop was
misplaced on e , it had to be removed also from the e-file as
White is going to occupy it with his rooks.

Karjakin probaby missed Black’s reaction! [ .Bf ! should
have been played, although Black is only very slightly worse

.Bxe fxe getting rid of the doubled pawns.
Black is slightly worse because of the f -f weakening of the
e pawn, although it should not be adequate a er Black
regroups his pieces with Re , Rad and Bb , with a flexible
position.]
...Qd !
An excellent move! Such tactical players like
Jobava easily find such ideas. Black is willing to sacrifice on
h ! It is actually very dangerous and from White’s point of
view it is not easy to prevent it at all.
.Bd
Karjakin is not afraid, he continues improving his
position. [ .Bf was much safer, but very passive. Black
could activate his pieces with ...Bf immediately occupying
the diagonal. .Qc a followed by Re and sometimes even
Be and f -f ideas could be dangerous.]
...Bxh !
Of course! Black is consequent. This sacrifice
cannot be calculated, only intuition helps, but Black can
easily foresee that a draw by perpetual check will always be
in his hand and he can decide to give it or to play for more.

...g !
Great play! Black wants to send away the knight with
g to be able to give a check on h . Objectively the game
is drawn, but in a practical game White has a much harder
task, because he must always choose between - seemingly
equivalent moves, but some of them could be worse than the
others.

[ .Ne was a tricky alternative, Black should react
precisely with ...Qe ! (

knight is under attack and then a check on h is possible. But

his strong attacking bishop on the board and he creates the
decisive threat of Rxd ! Nxd Bh Kh Bg and Qh -f mate.
