DRAGON TALES and TREATS

Blue_Dragon_by_mustanglover

 

The “Dragon” describes a vast complex variation in the Sicilian. Black sets up a fianchettoed bishop on g7, castles kingside, and hopes to attack on the queenside.

 

But where did the name Dragon come from?

 

So far, the research indicates that the name originated from the 19th century Russian player Fyodor Dus-Chotimirsk. He claimed to have invented the term in 1901 as Black’s kingside pawn structure resembled the constellation Draco. The constellation’s name means “dragon” in Latin.

 

It might also help to know that Dus-Chotimirsk was an amateur astronomer.

 

We can only assume that the fianchettoed bishop represents the head of the dragon while the bishop’s long diagonal is its tail. You will appreciate the long diagonal (tail) of the dragon after playing over a few games.

Here is an illustrated (AKA with diagrams) introduction to the Dragon.

[If this is how someone under 14 plays chess, I would not want to play him as an adult! What makes this game more interesting is the fact is that since Black moved his dragoned bishop off the long diagonal, White takes over the long diagonal and uses it for HIS bishop.]

A Dragon Trap

Curious-Blue-Dragon-and-Drake-Studying-Giant-Book-of-Magic-Statue-19-in.

You may know it already. Or maybe you just heard about it.

 

But there is a trap in the Sicilian Dragon which catches many players each year. Including Masters.

 

And if you can defeat a Master within a few moves of the game; well, it’s probably something worth memorizing.

 

First some background information.

 

The Sicilian Dragon is a large complex of moves and variation that all feature a fianchettoed bishop on g7.

 

This trap is to be found in the Levenfish Variation and is defined as 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.f4 (B71, if you are familiar with ECO).

The reasoning behind 6.f4 is to support a large center for White and to support a well-timed e5.

 

The first reason is easy to see. The second is not so easy as one has to visualize such a move (e5) and determine if it is a threat after each and every move.

 

In fact, many players do not suspect that .e5 may be coming so soon in the game and confidently, and yet innocently, play 6…Bg7?, which gives White a huge, almost winning, advantage.

 

The moves are 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.f4 Bg7. And now White plays 7.e5, which attacks the knight with White having a strong center and better mobility for his pieces.

 

Even not reaching the main trap of the line, Black can lose very, very fast.

17.Re5! 1-0

 

The prevalent thought among most Black players at this point to first remove the attacking pawn from e5 and then worry about the knight. This idea, while valid in many positions in chess, actually places Black in worse position, due to the now-opened lines White has his disposal.

 

Let’s review the moves once again.

 

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.f4 Bg7 7.e5 dxe5 8.fxe5

 

Black still has his knight under attack and he has to do something. Meanwhile, White has increased his attacking possibilities. White’s win is more certain.

How does Black get out of such mess if White was to play the Levenfish?

 

8.f4 Nc6!? is useful to Black as the Nc6 protects the Queen on d8.

Perhaps even better for White is 6.Be3, a favorite of Tal.

But Black can improve by NOT moving his Bishop so early. He can play after 6.f4, 6…Nbd7. This prevents any checks and the knight lays siege on e5, which also prevents .e5. The variation is known as Flohr Variation.

And Black, now playing this newer variation, can survive. At in least the opening.
