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
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
20. Rxe7+ Nxe7
Black cannot escape with 20. ... Kd8, in view of 21. Rxd7+! Kc8 22. Rd8+ Kxd8 (or 22. ... Rxd8 23. gxf3) 23. Be2+, winning.
21. Qxd7+ Kxd7 22. Bf5+ Ke8 23. Bd7+ Kd8 24. Bxe7 mate
