Opera game

From Wikipedia, the free encyclopedia

This article uses algebraic notation to describe chess moves.

The Opera Game was a famous chess game played in 1858 between the American chess master Paul Morphy and two strong amateurs, the German noble Duke Karl of Brunswick and the French aristocrat Count Isouard, who consulted, playing together as partners against Morphy.

The game is often used by chess teachers to demonstrate the importance of rapidly developing one's pieces, as well as other lessons.

[edit] The game

1. e4 e5

2. Nf3 d6

3. d4 Bg4 (?)

Though censured today, this was standard theory at the time. Now 3...exd4 or 3...Nf6 are usual. 3...f5 is a more aggressive alternative.

4. dxe5 Bxf3

If ... dxe5, then 5. Qxd8+ Kxd8 6. Nxe5 and White wins a pawn and Black has lost the ability to castle. Black, however, did have the option of 4...Nd7 5.exd6 Bxd6, when he's down a pawn, but has some compensation in the form of better development.

5. Qxf3 dxe5

6. Bc4 Nf6

This seemingly sound developing move runs into a surprising refutation. After white's next move, both f7 and b7 will be under attack.

7. Qb3 Qe7 (diagram)

Black's only good move. Almost all of black's moves lead to mate, for example 7. ... Nc6 8. Bxf7 Ke7 9. Qe6#. 7. ... Qd7 loses the rook to 8. Qxb7 followed by 9. Qxa8. Black is forced to move the queen to e7 which blocks the f8 bishop and more importantly impedes kingside castling.

8. Nc3

White prefers fast development to material. He declines to win a pawn with 8. Qxb7 Qb4+ (the only way to avoid loss of the rook) 9. Qxb4, or to win two with 8. Bxf7+ Kd8 (or 8. ... Qxf7 9. Qxb7 and now Black cannot avoid loss of the rook) 9. Qxb7, preferring to mass his forces for a quick checkmate and get back to the opera.

8. ... c6

9. Bg5 b5 (?)

10. Nxb5!

Morphy chooses not to retreat the bishop, which would allow Black to gain time for development. 9. ... b5 loses but it is difficult to find anything better; for example 9 ... Na6 10.Bxf6 gxf6 11.Bxa6 bxa6 12.Qa4 Qb7 and Black's position is in shambles.

10. ... cxb5?

Black could have played 10...Qb4+, which would have forced Morphy to exchange Queens, although White would retain a clearly won game

11. Bxb5+ Nbd7

12. 0-0-0

The combination of the bishop's pin on the knight and the open file for the rook will lead to Black's defeat.

12. ... Rd8 (diagram)

13. Rxd7 Rxd7

14. Rd1 Qe6

Compare the activity of the White pieces with the idleness of the Black pieces.

15. Bxd7+ Nxd7

If ... Qxd7, then 16. Qb8+ Ke7 17. Qxe5+ Kd8 18. Bxf6+ gxf6 19. Qxf6+ Kc8 20. Rxd7 Kxd7 21. Qxh8 and White is clearly winning.

16. Qb8+!

Morphy finishes with a stylish queen sacrifice.

16. ... Nxb8

17. Rd8#
