# Recognising the Pattern # 24

Today I am going to discuss one very common attacking formation with your knight on e5 (Ne5/Ne4) and Bishop on c4 (Bc4/Bc5), which generates enormous pressure on f2/f7 square whether the king is castled or not. Of course in order to accomplish the task you might need to use another pieces too.

Legal’s trap is based around this formation only. Here you can find the examples of this. But do remember that the pawn structure will ultimately decide the piece formation/placement and attacking patterns.

This is a training game against a friend of mine.
White : Ashvin Chauhan
Black : Jatin

1. e4 c5
2. Nf3 d6
3. d4 cxd4
4. c3 d3

The idea in playing a delayed Morra Gambit is to have it only against particular pawn formations. I mean I just love to play the Morra when Black’s d-pawn has moved from d7 to d6.

5. Bxd3 0-0
6. e5! dxe5
7. Nxe5 Bg7?

This natural move loses on the spot.

Q: How white should continue here?

A: Now white can win the good pawn on f7 with 9. Bc4!, which can’t be protected. 9…e6 fails to 10. Qxd8 followed by Nxf7 and 9…0-0 or Qxd1 then Bxf7 wins the pawn.

Variation from the game played between Mayet against Anderssen in 1851

Q: Black’s bishop is eying the f2 square and his knight is ready to jump on e4. In addition to that rook file is open but that cost Black a bishop. Can you justify is play?

A: The winning move for Black is 9…Nxe4, opening up h4-d8 diagonal for Black’s queen and therefore threatening …Qh4. There are four possible ways to stop it

Option 1: 10. Nf3 10…Ng3!! and mate can’t be prevented

Option 2: 10. Ng6 which is met by 10…fxe6, winning

Option 3: 10. g3 10…Bxf2+ is winning. Try to calculate all the variations.

Option 4: 10. Qxg4 is the obvious move but this fails to 10…Bxf2+ which leads to the win of the queen
11. Rxf2 Rh1+ 12. Kh1 Nxf2 forking king and queen.

These all are small blocks which should help you in recognizing complicated patterns. You can generate your blocks in conjunction with your openings for example in the Caro Exchange the knight on e5 and Bd3 is usual. But do remember the pawn formations!
