even with the extra material I would find facing Mamedyarov in this scenario a
truly frightening prospect. He's one of the best attacking players in the
world and the Benoni truly plays to his strengths - an ability to finely
appreciate the dynamics of a position. Jobava however seemed to go to a new

{German Bundesliga, Sunday morning. Nowadays starting at 10am, which is better
than 9am, but still....} 1. d4 Nf6 2. c4 e6 3. Nc3 c5 $6 {The first surprise.
Arkadij normally goes for the Nimzo and I hadn't seen him play the Benoni
before. After the game he told me "You looked so sleepy, I just had to make a
fight out of it". Of course it's a legitimate and fine strategy to opt for an
unbalanced fighting position being the stronger player. But I still don't
think his choice was clever here. First of all, he didn't have any experience
in the Benoni, and the resulting positions can be quite hard to play from the
black side. Secondly, while the position is complicated, White can just
develop his pieces normally and get a pleasant position without too many
pitfalls. So he failed in making me face too many tough decisions early in the
morning, in spite of the surprise.} 4. d5 exd5 5. cxd5 d6 6. e4 g6 7. h3 {
I decided to opt for the solid "modern main line" or whatever it's called.
Arguably 7.f4 is more critical, but it's not really in sync with my solid
cowardish style, especially without any preparation.} Bg7 8. Nf3 O-O 9. Bd3 Na6
$6 {The second surprise, and this time definitely a pleasant one. This move is
generally considered to be too slow and doesn't really interfere with White's
plans. Arkadij's trainer Beliavsky used it once, but as far as I can see, he's
the only strong player who ever actually won with it! The main line is ... b5,
but then again that move tends to lead to forced play and simplifications,
something that wasn't really on my opponents agenda.} (9... b5 10. Bxb5 Nxe4

is the main line, with Black regaining the pawn eventually. White seems to be
able to keep a tiny edge, but in practice Black has normally been able to hold.
}) 10. O-O Nc7 11. Re1 Re8 12. a4 b6 13. Bf4 {Simple chess. I'm just getting
the pieces out. Eventually, White is dreaming of Nd2-Nc4.} Ba6 14. Rb1 $1 {
Prophylaxis. The rook gets out of the range of Black's g7 guy, and more
importantly, I am now ready to counter the main idea of Black's setup
effectively: I am getting ready for b4 before Black can get in b5!} h6 {
A strange move, showing Black doesn't really have a constructive plan.} (14...
Bxd3 15. Qxd3 a6 16. b4 {and White is better.}) 15. Bh2 {As h6 didn't scare me
too much, I decided to bit some time and get my bishop out of possible furture
harrasment by means of g5 or Nh5.} Rc8 $2 {In my opinion, this is already the
decisive mistake. Now I get the chance to go for a forced sequence exploiting
Black's weaknesses on d6 and a7. Then again, its hard to come up with good
advice for Blacks cause already. As I said, I'm not a big fan of the Na6-Nc7
idea..} 16. Bxa6 $1 {I spent almost one hour on this move trying to calculate
stuff. It's not that logical, since I invite Black's knight to enter b4, but
who cares if it works? White is just quicker.} Nxa6 17. Nd2 Bf8 (17... Rc7 18.
Nc4 Rd7 {is more resilient, but its not a pretty sight either}) 18. Nb5 {

White remains a pawn to the good with a winning position. As they say, the
rest is a matter of technique. I never really got what that means though, I
guess the key is just to keep playing well even though you know that you have
a winning position?} Qxb7 26. Qxf6 (26. Bxf8 Nxe4 27. Bxh6 f5 {is less

Zickelbein told me b3 was a serious inacuracy accordig to her Fritz and Qf6
would be much stronger. My Fritz likes b3 though. And it does cover the a4
pawn, so I didn't really think twice about it. I like my pawns!} c4 {
Accelerating the end, but Black's position was fairly hopeless anyway.} 30. d6

unerheblich, ob der weiЯe Kцnig noch nach f6 gehen muЯ oder nicht. Zieht dann
der schwarze h-Bauer, so bringt WeiЯ seinen Randbauern wahlweise einen oder

allowing Black's expansion on the Q-side, White has a strong center and that's
where his chances lie. But Black has pressure on the half open e-file, thus
making it difficult for White to make any progress. Also an advance of the
Q-side pawns may be dangerous in favourable circumstances. Basically it can be
said White's typical central plan is much harder to realize without the
typical prophylactic a4.''} Bb7 (14... c4 $5) 15. Rac1 (15. Re2 c4 16. Bc2 Nc5

relatively rare plan. Black makes use of his advantage of space on the queen
side (resulting in the availibility of the seventh rank) to transfer his
queen'srook on the e-file and thus increase the pressure against the critical
e4- and e5-squares. While the attractive parts of this plan are obvious, there
are certain drawbacks, too, which are less easy to notice at a superficial
glance. First of all, White disposes over sufficient means to defend his
central pawn. At the same time, Black's queen side is slightly weakened by the
transfer of the rook to the other wing, especially that the knight's
development is considerably delayed. Finally, the rook is relatively exposed
on e7 (which can be seen in such cases when the thematic ...Nh5 is met by Bg5).

edition of the traditional Reggio Emilia tournament, I confessed to Vugar my
sincere admiration for his courage in playing the Benoni nowadays, as well as
for his ingeniosity and, not last, his excellent results. I remember him
mentioning the plan displayed in the present game and the name of Nakamura,
who once defended Black's point of view against strong opposition. Personally,
I have serious doubts about the merits of developing the bishop to b7. True,
the standard pawn break e5 is inhibited for a while, because it would leave
the d5-pawn weakened, but White can either prepare this break in a thorough
way or just switch to the alternate plan b4. In either case, the bishop is
doomed to passivity and so is Black. As a curiosity, I recently happened to
analyse a blocked position resulted from a hybrid between the KI and the BI. I
was shocked when one powerful engine suggested (in a rather normal position)
the manoeuvre ...Bd7-c8-b7-a8 as Black's second best line. Could it be that,
apart from providing doubtless help, computers tend to pervert our minds?!} 15.

glance. There is no easy way to make progress on the queen side, especially
because of the passive position of the bishop. Unfortunately, there is not
easy to transfer the bishop to d7 because ...Bc6 could always be met by Nc6.
On the other hand, Black's position is quite solid and hard to break. The
thematical advance of the e-pawn is not easy to carry out especially because
of the pressure against the d5-pawn (to which the bishop largely contributes).
And yet, it is only White who could hope for an advantage, Black's position
remaining rather defensive. Therefore, the decision of agreeing to a draw
might have had something in common with the respect for the opponent.} 1/2-1/2
