Qb6 $5 {An interesting, but unusual move that forces White to give up a pawn
in order to fight for an opening advantage. I met this variation for the first
time in the Arctic Chess Challenge last year against the winner of the Event,
Monika Socko. So I was far from surprised by this opening choce as Savchenko
had also played it before.} 9. Nf5 {The most principled move, grabbing the
pair of bishops and putting the black king in an insecure position. This is
obviously good compensation for giving up the pawn on b2, but can White hope
for more?} Qxb2 10. Nxg7+ Kf8 11. Nd5 ({Going for the black queen with} 11. Kd2

directed to the queenside as pushing f4 is not that relevant with the king on

After this move we enter the Dragadorf Variation, a Sicilian mix between the
Dragon and the Najdorf. This move was played by Alekhine already in 1945 but
it has a bad reputation and is known to be good for White. Of course playing
the Dragon a tempo down would be a decisive mistake, but with this setup Black
is searching for new ideas and often waits with the short castling so as not
to come under immediate attack. In recent times the variation has been taken
up on the reportoire by several strong GM:s and some even play it regularly. I
believe the variation is not at all that bad and even if it should be, it's a

forsaw that white was going to play Bg5-xf6, he is either a genius or a

h5 $6 {[%mdl 4] This ultra-modern approach is nowadays occasionally seen in
other Sicilians (for instance in some lines of Najdorf Variation).
Nevertheless, in Dragon such things can hardly succeed. The explanation is
that in Dragon Variation White's control in the center is event better than in
other Sicilians. He will arrange rooks on d1 and e1 and will have a strong
pressure on the central files. Unlike in other Sicilians, here Black usually
cannot remove the pawn from e7, since that would create visible weaknesses on
the d-file (of course, there are exceptions). As a result, White has always
better control over square d5 (and d4!). So in order to neutralize White's
central pressure, Black should create counterplay on the queenside. When White
develops harmoniously his pieces in the center (castle long, Bc4-b3, Rhe1),
it's not easy at all for Black to succeed in creating his queenside
counterplay. And without connecting his rooks, Black has practically no
chances. Thus any queenside actions with black king in the center will fail.
At some moment Black would have to castle short anyway. In that case, the pawn
on h5 is justified only with white pawn on h4. Otherwise White always keeps
the option to start a kingside attack by playing h3 and g4, like in our case. 
Concluding all mentioned above, after the move 8...h5 Black might always have
problems with the king (in the center he is much worse, queenside actions will
not succeed and the kingside is very vulnerable). White's plan is to develop
pieces in the center and keep the option to play h3 and g4. The present game
is a model one in that respect.} 9. O-O-O ({A different, but also effective
approach was demonstrated in the following game:} 9. Bc4 Bd7 10. Bb3 Na5 11.
O-O {Basically, here White intends to play only in the center. Black king can
be relatively safe on the kingside, but the move h5 is pretty ugly anyway. Any
central strategy from White will have bigger impact on Black's position For
instance he has square g5 in his possession, the advance of f-pawn will be
extremely unpleasant for Black. Finally, accidents like in the game are also a
logical consequence of ...h5.} Rc8 12. Nd5 Nxd5 13. exd5 Qc7 (13... O-O 14. f4
