{At the time of writing this column Shak Mamedyarov is perhaps the form player
of the world's top echelon - threatening to break through the 2800 barrier on
the live rating list (Ed: That barrier has subsequently been breached). He has
just recently claimed first prize in the strong Gashimov Memorial event in
Azerbaijan, ahead of Kramnik and So amongst others, and scored 4/4 for the
winning Siberian Team in the Russian Teams Event in Sochi. So it is
appropriate that I present one of his games. But to be honest it is no great
burden. Mamedyarov is one of the most dynamic and entertaining players in the
word and his games are frequently full of energy and tactical mazes. It was
also very easy to pick his recent game from the Sochi event against Evgeniy
Najer, another no nonsense player.} 1. d4 Nf6 2. c4 g6 3. f3 c5 4. d5 Bg7 5. e4
d6 6. Nc3 O-O 7. Bg5 h6 8. Be3 e6 {The opening is a King's Indian Saemisch of
course, but Mamedyarov now effectively converts it to a Modern Benoni - an
opening for which I have considerable affection. In the past the Benoni
featured often in the repertoires of tactical wizards such as Tal, Kasparov
and Nunn, but in recent years the Benoni has fallen away as an opening choice
of the top players in the world. I am pleased to say it seems to be creeping
back into fashion and often with some success. I would have thought the
opening would suit Mamedyarov down to the ground.} 9. Qd2 exd5 10. cxd5 {
Diagram #It is interesting to compare the characteristics of the different
white structures against the Benoni. The opening has a number of key themes.
Black has potential play on both sides of the board, looking to play b5 to
mobilise his queenside majority or, amazingly, h5, g5 or f5 to generate
activity on the kingside. White on the other hand has one primary goal and
that is to break through the centre with the e5 advance. For this reason I
find the f3 structures against the Benoni somewhat static for White.} Nh7 {
It is moves like this that make the Benoni such a rich opening. The move has
two clear goals, one is to indirectly protect the h6 pawn through the queen
check on h4, and the second is to free the 'f' pawn to attack the White
strongpoint at e4. But you have to say it probably isn't the first move to
come to mind!} 11. Bd3 Nd7 {Where would you choose to place White's king's
knight? There are two options, develop it rapidly to e2 or take an extra tempo
and end up with the beast on f2. To be honest I'm not crazy about either of
these squares. The knight belongs on f3 to support the e5 break in my book,
but that option is lost in this Saemisch structure.} 12. Nh3 Ne5 13. Nf2 f5 {
Black begins his kingside activity. His goal is to grab black square control
if he can by advancing his f pawn to f4, thus consolidating the beautiful
outpost on e5.} 14. Be2 g5 15. exf5 Bxf5 {Now things get exciting. White has
lost his strategic plan of breaking in the centre but Black has loosened his
kingside and White tries to capitalise on this immediately.} 16. h4 b5 $5 {
Diagram #And how does Black respond? In an apparently random way, by kicking
out on the opposite side of the board. But there is method in his madness.
Black is happy to sacrifice a pawn in order to open operations on the 'b' file.
White's king is safe enough for now but neither the kingside or queenside look
particularly inviting.} 17. hxg5 hxg5 18. Nxb5 Rb8 19. Nc3 {The engine reckons
that White is significantly better here but the point from Black's perspective
is that he has dynamic play all over the board and with that comes plenty of
opportunity to muddy the waters.} Qe8 20. Rc1 c4 21. O-O {The engine is more
enthusiastic about grabbing the 'a' pawn as well, but understandably White is
more interested in giving his king some security. Strangely it is probably
less safe on the kingside than in the centre.} Qh5 {Diagram #} 22. g4 $2 {
We reach the critical position. Najer must have relied on this response to the
queen sortie when choosing to castle.} ({A possible alternative} 22. f4 Qh4 23.
