[Event "Philadelphia"] [Site "?"] [Round "0"] [White "Martinez"] [Black "Steinitz"] [Result "0-1"] [ECO "C51"] [Opening "Evans Gambit Accepted"] 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4 { The Evans Gambit where White sacrifices a pawn for rapid development.} 4... Bxb4 5. c3 Bc5 {This move allows White to play d4 with gain of a tempo on the dark squared bishop. 5...Ba5 From a5 the dark squared bishop doesn't have to worry about losing a tempo when White advances pawn to d4.} 6. O-O d6 7. d4 exd4 {7...Bb6 is another possibility.} 8. cxd4 Bb6 9. Bb2 {Since the bisho p moves again in a few moves 9.Nc3 should be preferred. 9.Nc3 Bg4 10.Bb5 Kf8 11. Be3 would give White compensation for his pawn.} 9... Nf6 10. e5 {This move is inconsistent with White's previous Bb2 since e5 didn't need any preparation. 10.d5} 10... dxe5 11. Ba3 Be6 12. Nbd2 e4 {Black already has a won game as White has no compensation for his lost material.} 13. Re1 { Although this piece sacrifice does not work White decided to go down fighting.} 13... exf3 14. Qb3 Qxd4 {Black has his own attack on White's f2 square.} 15. Nxf3 {15.Bxe6 would allow Black a mate in two.} 15... Qxf2+ 16. Kh1 O-O-O { Now that the Black king has reached safety White could resign at any time.} 17. Rxe6 fxe6 18. Rf1 Ne4 {Black ends the game with a little combination based on White's weakened back rank.} 19. Rxf2 Nxf2+ 20. Kg1 Rd1+ { Takes advantage of White's weak back rank.} 21. Qxd1 { White resigned because of his material deficit.} 0-1
