Petrov's Immortal Game

Alexander Dmitrievich Petrov was born into a noble family and is usually remembered as the first great Russian chess master. From 1804, he lived in Saint Petersburg. In 1809, he defeated Kopev and Baranov, Petersburg’s leading chess players, and became Russian best player at the age of 15. Since then, over half a century Petrov was the strongest Russian player.

He is an author of the first chess handbook in Russian. He also analysed with Carl Friedrich von Jänisch the opening that later became known as the Petrov's Defense or Russian Game.

Petrov died in 1867, and was buried in the Russian Orthodox cemetery in Warsaw.

The following game is Petrov's best chess game and popularly known as "Petrov's Immortal Game".

F. ALEXANDER HOFFMAN vs. ALEXANDER PETROV
Warsaw, 1844
Italian Game: Classical Variation, Center Attack

1. e4,  e5
2. Nf3, Nc6
3. Bc4, Bc5
4. c3, Nf6
5. d4, exd4
6. e5, Ne4
7. Bd5? ....

Better is 7. cxd4 Bb4+, 8. Nc3 Ne4, 9. Qd2 ...

7. .... Nxf2!!
8. Kxf2?, dxc3+
9. Kg3, cxb2
10. Bxb2, Ne7
11. Ng5? ....

Much better is 11. Be4, preventing Black from deploying his Knight against the King, and avoiding Bishop-Knight exchange.

11. .... Nxd5
12. Nxf7! ....

If 12. Qxd5, Qxg5+.





12. .... 0-0!!

This Queen sacrifice paved the way for a very strong attack.  The f file is wide open!  Black could not have done any better.  If 12. .... Kxf7, 13. Qxd5+ and 14. Qxc5.  If 12. .... Qe7, then 13. Nxh8 followed by 14. Qh5+ or 14. Qxd5.

13. Nxd8, Bf2+
14. Kh3, d6+

Now, the two Black Bishops are active.

15. e6, Nf4+!!

Maintaining the strong attack of Bishop Pair.  Chess theory holds that the power of two Bishops working in tandem is one of the most powerful forces on the chessboard.

16. Kg4, Nxe6
17. Nxe6, Bxe6+
18. Kg5, Rf5+
19. Kg4, h5+!
20. Kh3, Rf3 mate.

Note that White's Queen has not moved an inch.  The most powerful game piece has been rendered useless.  Not only that, White's other pieces are still in their original positions.

Extraordinary!

The Center Game

The first opening we will talk about is the Center Game, which is used by tactical players.  The goal of this article is not to give you a historical development of the opening since you can easily find it elsewhere (for example here: http://en.wikipedia.org/wiki/Center_Game, but to give you its key features.

In this sharp opening, White usually castles on the Queen's Side and Black castles on the King's Side. As a result in many cases White pushes his 'h' pawn to create an attack.  In the game below, White did not.

ALLIES vs. BLACKBURNE
Hastings, 1894
(Center Game)

1. e4 e5
2. d4 exd4

White's second move has long been discredited because it leads to a loss of time when White's Queen is attacked. Besides, the Queen should not be moved too early in the game. The Queen is the strongest piece on the board and, after the King, she is easily the most valuable.  Be careful about bringing her into battle too soon.  She may herself become the target of an attack.

3. Qxd4 Nc6
4. Qe3 g6
5. Bd2 ...

Not a bad move, if White follows up with 6. Bc3 to neutralize Black's Bishop on the long diagonal -- but he doesn't.

5 ... Bg7
6. Nc3 N8e7
7. 0-0-0 0-0
8. f4  ...

Looks like a good attack, but according to Fred Reinfeld, this move is inferior to 8. Nd5 with a view to Bc3 to neutralize Black's Bishop.

8. ... d5!

Black is threatening d4 and seizes the initiative with this move.

9. exd5 Nb4!
10. Bc4 Bf5!

Every move a threat.

11. Bb3 N7xd5
12. Nxd5 Nxd5
13. Qf3 Qf6!

Another threat. This time...Qxb2 mate.

14. c3 Nb4!

Now, Black threatens Nd3ch followed by Ne5 or Ne1 winning White's Queen.

15. Bc4  ..

15.  ...  Qa6!

The Queen cannot be captured because of Nxa2! mate.

16. g4 Qxa2 !!

Black is unruffled. Now, he threatens Qa1 mate or Qb1 mate, so White makes room for his King.

17. Be3 Bxc3 !!

White resigns, as he is overwhelmed by simultaneous threats: Qa1 mate, Qxb2 mate, Qb1 mate. If Bkack's Bishop is captured, then White mates with Qc2. Black has played with heart-stirring brio.
