Idea #5 -  When white tries to prevent 8...d5 with 7.Bc4  --  Patterns to know

Let's take a look at the main line sequence:

1. e4        c5
2. Nf3     Nc6
3. d4       cxd4
4. Nxd4  g6
5. Nc3    Bg7
6. Be3    Nf6
7. Bc4    0-0

With 7.Bc4, White is signalling the intention to play a Yugoslav Attack while trying to prevent Black from playing 8...d5.  As usual, Black plays 7...0-0.   Now White proceed with caution, as it is easy to make a mistake.

Since Black will not be able to play 8...d5, I will show you 4 patterns to guide your response, depending on what White plays.

Pattern 1 -   White plays 8.f3 leaving the bishop on e3 undefended.

This position is common in amateur play.  White is continuing to try for the Yugloslav attack.
But 8.f3 is inaccurate for White, leaving the bishop on e3 unprotected.

Black can exploit this by playing 8...Qb6, attacking the unprotected pawn on b2, and an x-ray attack on the e3 bishop.

White's best choice is probably 9.Bb3, but this lets Black unleash the monster bishop with 9...Ng4 or 9..Nxe4 initiating tactics that favor Black.  (Note:  White can set a trap with 9.a3 hoping to trap the Black queen, but Black can avoid the poison pawn and play 9...Qc5.)



Pattern 2  -  White plays 8.Qd2 leaving the square g4 undefended.

This move is also common in amateur play.  White is again trying for a Yugoslav Attack, but unfortunately the move 8.Qd2 leaves the g4 square undefended.

Black takes advantage of this by playing 8...Ng4 with a discovered attack on the knight.

White cannot move the bishop without losing the knight, so will either have to give up his bishop for a knight, or play 9.Nxc6 with simplifications that favor Black.

Pattern 3 -   White plays 8.0-0 allowing the "fork trick"

Sometimes White gives up on a Yugoslav Attack and plays 8.0-0.

This allows the "fork trick" (a similar situation occurs in the Two Knights Defense) with 8...Nxe4.

If White recaptures with 9.Nxe4,  then 9...d5 forks bishop and knight.  

White can try 9.Bxf7+ leaving Black a rook on the semi-open f-file and two central pawns.

Pattern 4 -  White plays 8.Bb3 tempting the a-pawn to advance.

If White doesn't what to play into one of the 3 patterns above, the best move left is 8.Bb3, which avoids the fork trick, and might still lead to a Yugoslav Attack if Black complies.  This should probably be considered the main line.

The pattern for Black to notice here is a minor piece on b3.  When you see this, you should automatically consider 8...a5, threatening 9...a4.  

White has several replies, which will be covered in the next post.
