The game, move by move
Four Knights
- 1. e4 King’s pawn
- 1… e5 Symmetry
- 2. Nf3 Out
- 2… Nc6 Out
- 3. Nc3 Out
- 3… Nf6 Out The Four Knights: both sides develop knights before anything else, and nobody has committed to anything yet.
- 4. Bb5 The bishop to b5
- 4… Bc5 And the other to c5
- 5. O-O White castles
- 5… O-O And Black castles Ten half-moves, eight pieces out, two kings safe. Nothing in this position suggests what happens on move seventeen.
A pawn grabbed
- 6. Nxe5 A pawn taken White wins e5 — and gives Black the open file that decides the game.
- 6… Re8 The rook to the file at once Morphy does not recapture. The rook goes to e8 and stays pointed at White’s king for the rest of the game.
- 7. Nxc6 Taking the knight
- 7… dxc6 Recapturing with the pawn
- 8. Bc4 The bishop steps back
- 8… b5 Chasing it
- 9. Be2 And again
- 9… Nxe4 Winning the pawn back Black takes on e4, and the piece that recaptures is going to be taken by the rook.
- 10. Nxe4 Taken
- 10… Rxe4 And taken again The rook is on e4 in the middle of the board, which is where a rook is not supposed to be and where this one is untouchable.
- 11. Bf3 Hitting the rook
- 11… Re6 Sideways, still on the file
Both queens on the wing
- 12. c3 A quiet pawn
- 12… Qd3 The queen to d3 Deep in White’s position, holding the rook on e6 and stopping White from ever untangling. She will be given away from this square.
- 13. b4 Space on the queenside
- 13… Bb6 The bishop out of the way
- 14. a4 Another pawn
- 14… bxa4 Taken
- 15. Qxa4 The queen recaptures White is a pawn up with both rooks undeveloped and a queen on the wrong wing. Morphy has every piece pointing at g2.
- 15… Bd7 The last bishop out
- 16. Ra2 The rook to a2 Defending the second rank, which is the right idea two moves too late.
- 16… Rae8 Both rooks on the e-file Every black piece is now in the game and every one of them is aimed at the same corner.
- 17. Qa6 The queen goes hunting a6 attacks a rook. It also takes the queen as far from her king as the board allows, which is what Morphy has been waiting for.
- 17… Qxf3 The queen, for a pawn Qxf3. Black gives the queen for a bishop and a pawn, with no check and no immediate threat — and White has no way to stop the mate that follows.
The queen offered
- 18. gxf3 It has to be taken And taking is what opens the g-file.
- 18… Rg6+ The rook swings across Check, on the file the queen’s death opened.
- 19. Kh1 Into the corner
- 19… Bh3 The bishop joins Bh3 threatens mate on g2 and cannot be taken — the pawn that would do it is on f3, pinned to nothing and simply too far away.
- 20. Rd1 A rook, too late
- 20… Bg2+ Check
A rook and a bishop
- 21. Kg1 The king steps back
- 21… Bxf3+ Taking the pawn, with check
- 22. Kf1 And back again
- 22… Rg2 The rook to g2 Quiet, and mate is unstoppable. Black is a queen down and has three pieces on the king.
- 23. Qd3 A defensive queen move
- 23… Rxf2+ The rook takes f2
- 24. Kg1 The king in the corner
- 24… Rg2+ Doubling on g2
- 25. Kh1 The last square
- 25… Rg1# Checkmate A rook and a bishop, eight moves after the queen went. Morphy finished the game a queen and a rook down on material.
How it ends
Bb6 covers g1, Rg1 covers g2, Bf3 covers g2 and White's own pawn on h2 is in the way.
White gave up a bishop, 2 knights and 4 pawns; Black lost a queen, 2 knights and 2 pawns.
