The Sicilian Defence is the most common opening played in chess at all levels. It offers black good attacking prospects and can turn into a sharp tactical battle or a slower positional game, depending on the player’s preference.The Dragon variation of the Sicilian Defence can be an extremely aggressive line and is played frequently at GM level. The Najdorf variation is even more popular at GM level and we shall look at it in our next tournament.What is the difference between the variations? One little, seemingly unimportant pawn move!
Dragon – 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6
Najdorf – 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6
So what’s the big deal?
With 5 …g6, black develops his dark squared bishop so that it looks along the long a1-h8 diagonal. This immediately implies there will be some action on the queenside, especially considering the half-open c file where black can place a rook, looking into the depths of white’s position.
With 5 …a6, black spends more time moving pawns than getting his pieces out – going against traditional opening principles! So why is 5 …a6 so popular? We’ll deal with that when we start the Najdorf tournament.
The Accelerated and Hyper-Accelerated Dragons refer to where the g6 move comes in the move order – the earlier you play g6, the more accelerated the dragon! We currently have a tournament featuring the Hyper-Accelerated Dragon and will investigate the Accelerated Dragon sometime in the future.
Strategic thoughts:The exchange of black’s c pawn for white’s d pawn leaves black with a central pawn majority (he has more pawns in the centre). As the game progresses, black intends to push these pawns claiming more space and causing white some problems. In the meantime though, white has developed his pieces much more quickly and wants to get in a good attack before black has the chance to get his pieces developed and push those central pawns. By moving the bishop to g7, black has lost the natural defender of the pawn on d6, so any advance of the e pawn will leave the d6 pawn looking weak. Also, the d5 square looks like a nice place for one of white’s knights in the future. Black would like to push his pawn to d5 at some point, but white wants to stop this.
In the Dragon, black often decides to go for some counterattacking on the queenside using his pieces rather than worrying about trying to advance his central pawns. This is a bit counter-intuitive to the standard Sicilian strategy, but seems to be the way things often work out. Another common theme is the exchange sacrifice (swapping a rook for a knight) on the c file, messing up white’s queenside pawn structure and giving black some nice options in exchange for a material investment.
Sound interesting? Well, try out the Yugoslav attack if you really want some fireworks! (See below for the move order to reach this position). By castling queenside, white gets in a mad attack before black can unleash his own attack, leading to very sharp positions (a sharp position is one where there are lots of tactics going on while a quiet position has few tactical battles and more positional play).
Common VariationsWithin the Dragon variation there are several common options:Classical [B72] – 6.Be2 Bg7 7.Be3/0-0 or 6.Be3 Bg7 7.Be2Yugoslav Attack [B75-79]– 6.Be3 Bg7 7.f3 0-0 8.Qd2 Nc6Levenfish [B71] – 6.f4 Nc6By the way, the numbers given in square brackets refer to the ECO numbers for the openings – ECO is the Encyclopedia of Chess Openings.
