Paul Morphy's Evans Gambit is too wild

Evan's Gambit has the reputation of being one of the wildest openings from White and Paul Morphy is considered one of the best attacking players and probably the best player of his generation.
The game I will show was played between Paul Morphy and Alonzo Morphy on 29th Sep 1849.
The game is full of tactical beauties and is my favorite in the collection of Evan's Gambit games

So the game beings with

1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4 Bxb4 5. c3 Bc5

Usually, the idea in Evan's gambit is to target weak f7 pawn and prevent black from castling. White develops his pieces keeping these points in mind. But Morphy had a different plan. He re-attack the Bishop on c5 with d4 and claimed center. Black exchanges pawn in the center and white re-captures with cxd4 and gain full center.

6. d4 exd4 7. cxd4 Bb6 8. O-O Na5

Black choose to attack the bishop at c4 to avoid a situation where White plays Qb3 creating a queen bishop battery attacking the f7 pawn before Black could castle.
Other ideas are 8..Nf6 but e5 attacks the knight and forces him to move to uncomfortable e4 square where Rook develops to e1 with tempo by hitting the knight on e4. Black will end up moving the knight and white will attack the knight or other piece by developing his piece. So 8.. Na5 looks logical

The game continues, White plays Bd3 to save its Bishop

9. Bd3 Ne7 10. Nc3 O-O 11. Ba3 d6 12. e5 Bf5 13. exd6 cxd6 14. Ne4 d5 15. Nf6+!

Black quickly tries to castle in order to match the development of white. White pins the knight to the rook by playing Ba3 which black blocks with d6 and the exchange of pawns take plays. Black offers an exchange of light square bishop and white denies by playing Ne5 but this knight serves a dual purpose.
Black fails to recognize the threat and plays d5 hoping to push Knight away so that he can complete the exchange but here comes the attack. White temporarily sacs the knight by playing Nf6+. If black doesn't capture the knight then White will capture the f5 bishop and later the rook if the knight recaptures White's bishop. Hence black chooses to capture the knight and accepts the damaged structure on the king's side.

Now White removes the defender of the bishop (e7 knight) and looks to capture the bishop on f5. If Black captures the white bishop then he loses the queen. Hence black recaptures the bishop with Qxe7 and white captures the f5 bishop to equate material

15.. gxf6 16. Bxe7 Qxe7 17. Bxf5 Nc4

After this, The material is equal, black's King's side is damaged. White just has to move the knight for his queen to join the attack, on the other hand, black doesn't have any immediate attack.
Black centralizes the knight with Nc4.

White seems to have a clear plan, bring the queen to the king's side. Create an attack on the H file's pawn and check-mate the black king.
White begins with Re1 attacking the queen

18. Re1 Qd6 19. Ne5 fxe5 20. Qg4+ Kh8 21. Qh5 Kg7 22. Qg4+ Kh8 23. Qh5 h6

Once the queen moves to d6 White sacs the knight (19. Ne5) and, launches an attack on the black's king.
Black accepts the sacrifice with fxe6 and White begins the attack with Qg5. few and after a few moves we reach the above position where the black queen supports the h6 pawn and prevents the attack.
White now devices a plan to block this queen's support to the h6 pawn. If white is able to do it just for one move, then the checkmate will become inevitable.

Morphy goes all gun blazing to block the queen's support. He doesn't care about anything else but to block this path. He begins by sacrificing the rook

24. Rxe5 Nxe5 25. dxe5 Qc6 26. e6 Kg7 27. g4 Qc3 28. g5 Qxa1+ 29. Kg2 Qf6

White sacrifices the rook and Black gladly accepts this by capturing the rook with the knight. White captures the knight attacking the queen. and queen slides to c6. Notice Queen can't capture the pawn as Qxh6 Kg8 Qh7#.
Although it looks like White is able to block the queen's support with e6 but black's king reaches g7 to support the h6 pawn just in time. Hence this rook sacrifices, although looks stunning but is a blunder and here White is losing. White still hopes to create something and plays g4 hoping for g5 Hxg5 Qh7+ or something alike. but Queen goes to c3, threatening to capture Rook with a check.
But Morphy is in no mood for defense and plays g5. Black captures the rook with check and white plays Kg2
Now, here, white looks like having multiple attack points

Here black loses patience and makes a huge blunder. In the above position, black has just one move that keeps him in winning advantage. Take a pause and see the above position with black to play. You can also play this position against an engine, both as white and as black.

I am not telling you the best move here but Black plays Qf6. Black sacrifices the queen in the hope of activating his pieces and slowing down White's attack. Also, he will have 2 rooks for a queen and a bishop for a bishop.

White accepts the sacrifice with gxf6+ and the king recaptures the pawn

30. gxf6+ Kxf6 31. exf7 Rxf7 32. Qg6+ Ke7 33. Qe6+ Kf8 34. Qxh6+ Rg7+ 35. Bg6 Kg8 36. h4 d4 37. h5 d3 38. Qg5 Rd8 39. h6 d2 40. Qf6 Rgd7

Black looks to centralize his pieces and promote d pawn to the queen and again white doesn't care about it and galops h6 pawn cornering Black's king while Black threatens to promote the pawn to the queen.

White plays Bf5 attacking the rook but Black promotes the pawn to the queen. White understands that capturing the rook won't make any sense so White pushes the pawn to h7 delivering a check to the black king and Black chops off the pawn.

Bf5 d1=Q 42. h7+ Rxh7

and now begins a perfect checkmate sequence

43. Be6+ Rf7 44. Bxf7+ Kh7 45. Qg6+ Kh8 46. Qh6#

So that was one of my favorite games from Evan's gambit. It wasn't a perfect game as Black has a decisive advantage after White's rook sac but the human brain has its own limitation. After being under such bombardment black might have felt at ease only after the queen's promotion but until then it was too late.
