Paul Morphy's King's Gambit

New Orleans, 1849
King's Gambit Accepted, Kieseritzky Variation, Cotter Gambit

1.  e4, e5
2. f4, exf4
3. Nf3, g5
4. h4, g4
5. Ng5, h6

An offshoot of the Kierseritzky Gambit.  White sacrifices a Knight to break down Black's defenses.

6. Nxf7, Kxf7
7. Qxg4, Qf6

Black defends the f4 pawn.

8. Bc4+, Ke7
9. Nc3, c6
10. e5!! ....

A surprise move!  Here, White intends to open the e-file for a strong attack on Black's King.

10. ..... Qxe5+

Black accepts the challenge, for he has nothing better.  If 10....Qg7, 11. Qxf4 d5, 12. exd6+ (e.p.) and Black's defense collapses.

11. Kd1, Kd8
12. Re1, Qc5
13. Bxg8, d5
14. Re8+, Kxe8
15. Qxc8, Ke7
16. Nxd5+!! .....

White takes advantage of the pin on Black's Queen at c6, rendering White's Knight immortal.

16. ..... Kd6
17. Qc7 mate

White may also mate at e6, but the current position makes a picturesque mate.

King's Indian Defense of Bobby Fischer

King's Indian Defense

1. d4, Nf6
2. c4 g6
3. Nc3, Bg7
4. e4, d6
5. Nf3, 0-0
6. Bd3, Bg4
7. 0-0, Nc6
8. Be3, Nd7
9. Be2, Bxf3
10. Bxf3, e5
11. d5, Ne7

All prior moves are standard lines for King's Indian Defense.  Black's last move is a preparation for the eventual f5! which is aimed at dismantling White's central pawn structure.

12. Be2 ....

White also prepares for f4.

12. .... f5!
13. f4, h6
14. Bd3, Kh7
15. Qe2, fxe4!
16. Nxe4, Nf5!

The reason for Black's 15th move.  He is seeking a good post for his Knight.

17. Bd2, exf4
18. Bxf4, Ne5
19. Bc2, Nd4!

Excellent horsemanship.  The two knights are working in tandem to render White's Bishop Pair ineffective.

20. Qd2 ....

White has no choice.  If 20. Qf2, the game proceeds as in move 21.

20. .... Nxc4!
21. Qf2, Rxf4!!

Excellent play!  if White declines the offer, another piece (Bishop) will go down.

22. Qxf4, Ne2+
23. Kh1, Nxf4

White resigns.  He has lost his Queen.
