Paul Morphy (1837-1884) beat every top player he met in 1857-1859, then left serious chess. He never had an Elo rating, because ratings came a century later. So how strong was he? This page puts the historical rating estimates in one table with their sources, lists his match results, compares him with Magnus Carlsen, and lets you replay the Opera Game and two more of his best games on a board.
Paul Morphy never had an Elo rating. The Elo system was first used by the US Chess Federation in 1960 and by FIDE in 1970, almost a hundred years after his last serious games. Every number you see for Morphy is a historical estimate, made later from his old results.
Three well-known systems have rated him. Arpad Elo himself, the man who made the Elo system, did it in his 1978 book. Jeff Sonas did it with Chessmetrics, and Rod Edwards with the Edo ratings. They use different methods, so they give different numbers. All three agree on one thing: Morphy was the strongest player in the world in 1858 and 1859. How the Elo system works is explained in Elo rating in chess.
| Rating system | Made by, year | What it measures | Morphy | Next best of his time |
|---|---|---|---|---|
| Elo historical list | Arpad Elo, book The Rating of Chessplayers, Past and Present (1978) | Best five-year average | 2690 (6th in the list) | - |
| Chessmetrics | Jeff Sonas (2005) | Highest monthly rating | 2743 (June 1859 list, world No. 1) | Anderssen 2633, Loewenthal 2616 (same list) |
| Chessmetrics | Jeff Sonas (2005) | Best one-year average | 2737 (1859) | - |
| Chessmetrics | Jeff Sonas (2005) | Best single event | 2686 (match vs Anderssen, 1858, 8/11) | - |
| Edo rating | Rod Edwards | Rating for each year, with an error margin | 2812 ±46 (1860, his peak); 2802 in 1857, 2795 in 1858, 2809 in 1859 | Anderssen 2627, Loewenthal 2627 (1858 list) |
| FIDE Elo | FIDE, from 1970 | Official rating | None. He died in 1884. | - |
Read 4 November 2026 from the sources linked in the first column. Elo's number is quoted by ChessBase (30 Aug 2003). The three systems use different scales, so their numbers are not the same thing as a modern FIDE rating.
Why are the numbers so different? A historical rating can only measure a player against the players of his own time. Elo used a five-year average, so the short Morphy career pulls his number down. Chessmetrics drops a player's rating when he stops playing, and Morphy played few serious games after 1859. Edo looks at every match year by year and also counts the many games he played while giving odds (a knight or a pawn) to weaker players. The safest way to read the table: Morphy was about 100 to 200 points above the next best player of his time, in every system.
He beat every leading master he played in a match. In just over a year (1857-1858) he won the First American Chess Congress and then beat the best players in London and Paris. At age 12, in New Orleans, he had already won casual games against the visiting master Johann Loewenthal.
| Opponent | Where and when | Type | Morphy won | Drawn | Morphy lost |
|---|---|---|---|---|---|
| James Thompson | New York 1857 (Congress, round 1) | Knockout match | 3 | 0 | 0 |
| Alexander Meek | New York 1857 (Congress, round 2) | Knockout match | 3 | 0 | 0 |
| Theodor Lichtenhein | New York 1857 (Congress, semi-final) | Knockout match | 3 | 1 | 0 |
| Louis Paulsen | New York 1857 (Congress, final) | Knockout match | 5 | 2 | 1 |
| Johann Loewenthal | London, July-August 1858 | Match | 9 | 2 | 3 |
| Daniel Harrwitz | Paris, September-October 1858 | Match | 5 | 1 | 2 |
| Adolf Anderssen | Paris, December 1858 | Match | 7 | 2 | 2 |
| Alfred Mongredien | Paris 1859 | Match | 7 | 1 | 0 |
Sources: Wikipedia (First American Chess Congress, Paul Morphy) and the Edo match pages. For the Loewenthal match most sources, Loewenthal himself among them, give +9 -3 =2; a few (Staunton in the Illustrated London News) give three draws. Harrwitz gave up the match after game 8.
He also played many games while giving odds, and he offered pawn-and-move odds to any player in the United States. The one famous match that never happened was against the English champion Howard Staunton. After he went home to New Orleans in 1859 he played almost no serious chess again. He died on 10 July 1884, aged 47. More players from that time are in the history of chess and our famous players hub.
The Opera Game is a short win by Morphy in Paris in 1858, played in a box at the opera house. His opponents were the Duke of Brunswick and Count Isouard, who played Black together. Morphy (White) won in 17 moves. It is one of the most shown games in chess, because it teaches the basics so clearly: develop fast, open lines, and use every piece. It is also in our list of the most famous chess games.
Which opera was playing is not clear: Max Lange and David Lawson name The Barber of Seville, other sources name other operas.
What to learn: Develop first, then attack. By move 12 all of Morphy's pieces were playing and two of Black's had never moved. That is why the sacrifices on b5, d7 and b8 all worked.
Morphy won it without losing a match. The congress ran in New York from 6 October to 10 November 1857. Sixteen top American players met in a knockout; draws did not count. Morphy beat James Thompson, Alexander Meek and Theodor Lichtenhein, then Louis Paulsen in the final with five wins, one loss and two draws. He refused the $300 first prize and took a silver service instead.
The best-known game of the final is Paulsen vs Morphy, with the queen sacrifice 17...Qxf3!!. Jump to move 17 on the board.
Key idea: A queen for a bishop is a fair trade when it strips the enemy king. After 17...Qxf3 the king on g1 had no pawn cover, and Black's rooks and bishops did the rest.
Most lists start with the Opera Game (1858) and Paulsen vs Morphy (1857), both on the boards above. A third favourite is his win against Henry Bird in London, 1858, with the rook sacrifice 17...Rxf2 and the quiet queen move 18...Qa3!!. Strong players still argue whether the rook sacrifice was fully correct, and Stockfish today is not sure either. It is still a great example of how Morphy opened the enemy king.
Key idea: When the enemy king castles long, the a- and b-files are the way in. Morphy gave a rook to open them, and Bird's one wrong king move (22.Kb2?) was enough to lose.
No rating can answer this fairly, because the two never played the same opponents. Magnus Carlsen's peak of 2882 (FIDE, May 2014) is a real Elo rating, earned against modern grandmasters. Morphy's numbers in the table are estimates on other scales, measured against the players of the 1850s.
So the fair answer: Carlsen would win a match today because he knows far more chess; Morphy, for his time, was just as dominant. For a modern comparison of the same kind see Magnus Carlsen vs Bobby Fischer.
He was clearly the best of his own time; whether he was the best ever is an opinion. Chessmetrics has him as world number one in 39 different months (September 1858 to November 1861), and Edo has him first every year from 1849 to 1867.
Great players disagree about the rest. Bobby Fischer put Morphy first in his 1964 list of the ten greatest masters and called him "perhaps the most accurate player who ever lived". Viswanathan Anand named him in his top ten (2000), and Hikaru Nakamura put him tenth in his 2021 list. Larry Kaufman (2023) wrote that Morphy "might have rivaled Fischer for the top spot if we could properly correct for these factors". There was no official world championship in his day: the first one was Steinitz vs Zukertort in 1886, two years after Morphy died. See every official number one in world number 1 chess players.
He never had an official one; FIDE ratings started in 1970. Historical estimates: 2690 in Arpad Elo's 1978 book (best five-year average), 2743 at Chessmetrics (June 1859, world No. 1) and 2812 in the Edo ratings (1860).
He beat every top player he met in a match: Paulsen (1857), Loewenthal and Harrwitz (1858) and Anderssen (December 1858, seven wins, two draws, two losses). Rating systems put him 100 to 200 points above the next best player of his time.
They cannot be measured on one scale. Carlsen's 2882 (May 2014) is a real FIDE rating; Morphy's numbers are estimates against 1850s players. Carlsen knows far more chess, while Morphy was just as far ahead of the players of his time.
A casual game Morphy won in 17 moves in Paris in 1858, in a box at the opera house, against the Duke of Brunswick and Count Isouard. It ends with a queen sacrifice and 17.Rd8 mate.
Not officially. The first official world championship match was Steinitz vs Zukertort in 1886, after Morphy's death. After his 1858 wins many people saw him as the best player in the world.
After he came home to New Orleans in 1859 he played almost no serious chess again and tried to work as a lawyer. He died on 10 July 1884, aged 47.
