The Women’s World Championship is coming to an end. The
two finalists are Natalija Pogonina from Russia and Mariya
Muzychuk from Ukraine. Both players were fighting very hard
to reach the final stage of the event. The score is . - . to
Muzychuk, but the final consists of classical games. Despite
being behind, Natalija Pogonina must still feel confident,
since she passed the last three(!) rounds a er losing the first
game of the match, but she always equalized in the second
and went through in the tiebreak.
The very strong Aeroflot Open in Moscow is also coming
to its conclusion. Before the last round the sole leader is
Ian Nepomniachtchi with the amazing score of . / . Three
young GMs, Ivan Bukavshin, Daniil Dubov and Lu Shanglei are
just half a point behind him.
The US Championship has just started. We expect a huge
fight for the first place between Hikaru Nakamura and Wesley
So. They have already shown their intentions to the field by
getting o to a great start with / . However the field is full
of very talented young players, who can cause surprises at
any moment and obviously one should never forget about the
reigning champion, Gata Kamsky.
As usual we wish you a lot of fun with the current issue! Enjoy!

Best rating:
but in a much better version because he is sparing tempi.
The drawback is clearly that Black opens the center too fast,
while his king is still in the middle of the board. White has two
moves to make use of it, otherwise Black develops with Nf
and - and he is completely fine. [More normal was to finish
the development with ...Nf and - .]

Vadim Zvjaginsev was always a very resourceful player with
extraordinary imagination in unusual positions. He is also
known for his creative opening play...

Obviously this move cannot
create real problems for Black, it rather aims at avoiding a
theoretical battle.
...Bc
Black keeps the structure closed. [An alternative is
...Nf attacking the e pawn and a er .Nc or .d , d leads
to a completely di erent game.]
.Bg d
.O-O
.b !!
A brilliant resource, extremely creative play!
Zvjaginsev follows the principle that he must open the
center on the king. He wants to play d , but first he lures one
of the minor pieces to b in order to make the real plan more
e ective.
...Bxb
It is important to keep the knight on c to keep
the position together. It protects the e square a er White
plays d . [The black pieces become much more confused
a er ...Nxb .d ! This is a position which is impossible
to calculate before .b , one must have the intuition that
White’s compensation should be more than enough. The
following lines seem to confirm it. ...Nxc (

This is a recurring motif in this game. The
bishop does not have a square to protect the c knight and

for Black. The king faces an enormous attack and the knight

A highly ambitious move. The point is that in positions
with Nf and - a standard idea is to play something like h

Black must delay castling with another move, because White

...Bb
.Nh
Very concrete chess! White wants to
achieve the maximum as long as the king is still on e .
It all looks perfect for Black. He manages to trade queens and
the a rook is caught, but suddenly the dark squared bishop
becomes a hero.

it with the queen, for instance ...Qd is refuted by .c !

Black must focus on quickly finishing the
development. [ ...exd .Nxd ]

It is important to open the diagonal to b and a for the
queen. This is the only way to gain some direct benefits before
Black can castle.

[The alternative .Qb to prevent castling
also looks pretty interesting, although a er ...Qd with the
idea of Be

alright.]
...Nb
.Qa + c
Black saves the piece, but he critically
weakens his pawn chain, which allows White to organize his
counterplay.
...O-O
Finally Black castles, but losing the light squared
bishop is a very sad scenario for him. The power of the g
bishop increases heavily by this and the pressure on the c
pawn increases even furter. But of course Black is still a
pawn up, since the th move... [ ...Bd could have been
met by .Qb ! keeping the king in the center. White
could strengthen his position with Nd -c . ...c ? locks the
position and lets Black castle next move, but this move is a
positional disaster a er .Na ! and Nc . The black pieces
and his pawn structure are just terrible.]

The most natural move to keep the
annoying pin alive, but perhaps it was not objectively the
best. [The simple .Bxe

.Nd seems to give
White a pleasant edge. Black has di iculties with finishing
the development of his queenside. The only way to do it is
by giving back his extra pawn ...Nd but now he ends up

The e knight is extremely strong. It attacks the target on d
