Rosenthal – Steinitz, Vienna 1873


Steinitz began the era of scientific play, as his games and writings demonstrated that games were won or lost for objective reasons. Here he provides a (then startling) example of the proper use two Bishops against a Bishop and Knight.

Rosenthal – Steinitz
Vienna, 1873

C46 THREE KNIGHTS GAME


1. e4 e5 2. Nc3 Nc6 3. Nf3 g6 4. d4 exd4 5. Nxd4 Bg7 6. Be3 Nge7 7. Bc4 d6 8. 0-0 0-0 9. f4 Na5 10. Bd3 d5 11. exd5 Nxd5 12. Nxd5 Qxd5 13. c3 Rd8 14. Qc2 Nc4 15. Bxc4 Qxc4 16. Qf2 c5 17. Nf3 b6

Black deprives the Knight of support squares in the center, and the Be3 “bites on granite.” Black has a clear advantage.

18. Ne5 Qe6 19. Qf3 Ba6 20. Rfe1 f6

If the Knight had a secure central square ... but it hasn’t, and it’s not going to get one.

21. Ng4 h5 22. Nf2 Qf7 23. f5 g5 24. Rad1 Bb7 25. Qg3 Rd5 26. Rxd5 Qxd5 27. Rd1

White can’t defend the f5 pawn with 27. Qh3 because of 27. ... g4.

27. ... Qxf5 28. Qc7 Bd5 29. b3 Re8 30. c4 Bf7 31. Bc1 Re2 32. Rf1 Qc2 33. Qg3 Qxa2, White resigns

Matchego - Falkbeer, London 1869


In playing over these old games, it is best not to ask too many questions about the defender’s play — the gap between master and amateur was often enormous — but relax and enjoy the tragicomic plight of the White King, as he is driven across the board and mated with his pieces still at home.

London, 1869

C39 KING’S GAMBIT ACCEPTED


1. e4 e5 2. f4 exf4 3. Nf3 g5 4. h4 g4 5. Ne5 Nf6 6. Nc3

White’s set-up (known as the Kieseritsky Gambit) is acceptable — he can recover either the g5 or f5 pawn — but he should now play 6. d4, to answer 6. ... d6 with 7. Nd3.

6. ... d6 7. Nc4 Be7 8. d4 Nh5 9. Be2 Bxh4+ 10. Kd2 Qg5 11. Kd3 Nc6 12. a3 Bf2 13. Nd5 Bxd4 14. Nxc7+ Kd8 15. Nd5

The alternative 15. Nxa8 is no worse than the game, but it runs into something like 15. ... d5 16. exd5 Bf5+ 17. Kd2 f3+ 18. Ke1 f2+ 19. Kf1 Ng3 mate.

15. ... f5 16. Nxd6 fxe4+ 17. Kc4

Instead, 17. Kxe4 Ng3+ 18. Kd3 Qxd5 loses routinely.

Anderssen - Dufresne, Berlin 1852


White sacrifices a piece to open the central files against the uncastled Black King, and despite his seemingly adequate development and counterattacking chances Black comes out a tempo short in one of the finest combinations on record, known as the “Evergreen Game.”

Anderssen – Dufresne
Berlin, 1852
C52 EVANS GAMBIT
1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4

The Evans Gambit, in which White sacrifices a flank pawn for rapid development and a powerful center.

4. ... Bxb4 5. c3 Ba5 6. d4 exd4 7. 0-0 d3 8. Qb3 Qf6 9. e5 Qg6 10. Re1 Nge7 11. Ba3 b5

Black in turn gives back a pawn to complete his development, but White’s control of the center makes it difficult for Black to coordinate his forces.

12. Qxb5 Rb8 13. Qa4 Bb6 14. Nbd2 Bb7 15. Ne4 Qf5 16. Bxd3 Qh5 17. Nf6+

A temporary piece sacrifice to exploit the exposed position of the Black King. But this is not without risk, as Black now obtains an open g-file for counterplay.

17. ... gxf6 18. exf6 Rg8 19. Rad1!

Offering a second piece, and far stronger than the defensive 19. Be4.

19. ... Qxf3

Black cannot escape with 20. ... Kd8, in view of 21. Rxd7+! Kc8 22. Rd8+ Kxd8 (or 22. ... Rxd8 23. gxf3) 23. Be2+, winning.

Paulsen - Morphy, New York, 1857


Paul Morphy competed in only one tournament in his brief career, the First American Chess Congress in 1857. In the final round of this knock-out event, he defeated German master Louis Paulsen by a score of +5=2-1. In this game he demonstrates both his superior grasp of positional play — Black’s control of the center files makes a marked contrast to White’s flailing on the flanks — and his combinative ability, as he finishes the game with a startling Queen sacrifice.

Paulsen - Morphy
New York, 1857

C48 FOUR KNIGHTS’ GAME


1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Bb5 Bc5 5. 0-0 0-0 6. Nxe5 Re8

Rather than permit the “fork trick” 6. ... Nxe5 7. d4, Black sacrifices a pawn for rapid development.

7. Nxc6 dxc6 8. Bc4 b5 9. Be2

The seemingly more logical 9. Bb3 fails to 9. ... Bg4 10. Qe1 (or 10. Ne2 Rxe4, winning the pinned Knight) 10. ... b4, and if 11. Na4 Rxe4 traps the White Queen.

9. ... Nxe4 10. Nxe4 Rxe4 11. Bf3 Re6 12. c3?

If White were able to follow up with d2-d4 this would be a good move, but it can’t be done. He should reconcile himself to the modest 12. d3.

12. ... Qd3! 13. b4 Bb6 14. a4 bxa4 15. Qxa4 Bd7 16. Ra2 Rae8

Threatens mate with 17. ... Qxf1+. White’s reply defends against this sacrifice, but allows another, which, however, Paulsen can hardly be blamed for missing. Relatively best was 17. Qd1.

17. Qa6

(Diagram)

17. ... Qxf3! 18. gxf3

Morphy took twelve minutes to decide on 17. .. Qxf3, an unusually long time for him. Paulsen, a notoriously slow player, thought for over an hour before capturing the Queen.

18. ... Rg6+ 19. Kh1 Bh3 20. Rd1

Black threatened 20. ... Bg2+ 21. Kg1 Bxf3 mate, and 20. Rg1 fails to 20. ... Rxg1+ 21. Kxg1 Re1+. The key line, which Paulsen probably missed on move 17, is 20. Qd3 (hoping to return the Queen with Qxg6) 20. ... f5!, and White is helpless.

20. ... Bg2+ 21. Kg1 Bxf3+ 22. Kf1 Bg2+ 23. Kg1 Bh3+ 24. Kh1 Bxf2 25. Qf1 Bxf1 26. Rxf1 Re2 27. Ra1 Rh6 28. d4 Be3, White resigns
