Recognising the Pattern # 25

Today we are going to see another common attacking formation with your knight on e5 (or e4 as Black) and bishop on b5 (b4 as Black). It is usually more effective when the bishop’s counterpart is not able to defend the d7 (d2) or c6 (c3) square. Again you must consider surrounding pawn structure before launching the attack as pawns are the natural blockader of lines. Here is the trap in the Chigorin defence that involves this attacking formation:

Martial Larochelle (2230) against Olivier Tessier (2215) in 2007

1. Nf3 Nc6
2. d4 d5
3. c4 Bg4
4. Nc3 Nf6
5. cxd5 Nxd5
6. e4 Nb6
7. d5 Ne5

Black thought that the knight on e5 can’t be touched because of pin on f3. In fact this is blunder that loses at least a piece.

8. Nxe5!!

With the idea of exploiting the weakness on d7/c6 with the coordination of the bishop on b5, knight on e5 and pawn on d5.

8… Bxd1

9. Bb5+ c6

If 9…Nd7 then Bxd7 wins material and 9… Qd7 loses the queen.

10. dxc6

Threatening to win queen with c6-c7 discovered check.


Hoping for 11. c7 Qd7 12.Bxd7?

Other options are also not viable, for example:

A) 10…Qc7 11. cxb7 Kd8 (if 11…Nd7 then bxa8=Q wins) 12. Nxf7#

B) 10…Qb8 11. c7+ Nd7 12 Bxd7#

c) 10…bxc6 11. Bxc6 Nd7 12. Bxd7 Qxd7 13. Nxd7 wins the material (Berliner against Rott in 1956)

11. c7+ Qd7

12. Nxg4!

White is not in a hurry to recapture the queen. Black resigned here.
