New York 1857: The First American Chess Congress
The First American Chess Congress opened in New York in October 1857, a sixteen-player knockout modelled on the great London tournament of 1851 organised by Howard Staunton. The American event was conceived in part to discover whether the United States possessed a player of world class. It did. Paul Morphy, a 20-year-old from New Orleans who had barely played serious chess in two years, cut through the field and reached the final against Louis Paulsen, a German-born player living in Iowa who was famous for his blindfold displays and his almost glacial deliberation at the board.
The final was decided by the first to win five games. Morphy dominated it, eventually winning by five wins to one with two draws, but the match is remembered above all for its sixth game. Paulsen had White and opened with a Four Knights, a quiet, symmetrical system suited to his cautious style. The opening moves, 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 Bc5, gave no hint of what was coming. By move 17 the game had become one of the defining moments in chess history.
The Position Before the Storm
Paulsen handled the opening passively. After 5.O-O O-O 6.Nxe5 Re8 7.Nxc6 dxc6 8.Bc4 b5 9.Be2 Nxe4 10.Nxe4 Rxe4 11.Bf3 Re6 12.c3, the material was level but the character of the position was not. Morphy's pieces pointed at the white king while Paulsen's sat tangled on their starting squares. With 12...Qd3 Morphy planted his queen deep in White's camp, a clamp on the position that Paulsen never managed to remove.
Paulsen spent the following moves on queenside gestures: 13.b4 Bb6 14.a4 bxa4 15.Qxa4 Bd7 16.Ra2 Rae8. Every Black piece now participated in the attack, both rooks doubled on the e-file, both bishops aimed at the kingside. Then came the decisive provocation. With 17.Qa6 Paulsen offered an exchange of queens, expecting 17...Qxa6, which would have relieved all the pressure at once. It was a reasonable practical try from a defender under strain, but it removed White's queen to the edge of the board at the exact moment the centre of gravity of the game was the white king. Morphy saw what that meant, and students of chess strategy have been studying his answer ever since.
17...Qxf3: The Move Itself
Instead of trading queens, Morphy played 17...Qxf3, capturing the bishop on f3 with his queen and leaving it where the g2 pawn could take it. Paulsen, after long thought, accepted with 18.gxf3, and the logic of the sacrifice unfolded with terrible clarity: 18...Rg6+ 19.Kh1 Bh3. The white king was now sealed behind its own wrecked pawns. Black threatened mate on g2, the rook on f1 could not move without allowing it, and the white queen watched helplessly from a6.
Paulsen tried 20.Rd1, and Morphy continued 20...Bg2+ 21.Kg1 Bxf3+ 22.Kf1 Bg2+ 23.Kg1 Bh3+ 24.Kh1 Bxf2. For the queen Morphy had collected a bishop and two pawns, but the count of wood was beside the point. White's king had no shelter, no defenders, and no prospect of ever finding either. After 25.Qf1 Bxf1 26.Rxf1 Re2 27.Ra1 Rh6 28.d4 Be3, Paulsen resigned, facing unstoppable mate. The full game appears in every serious anthology of famous chess games, and 17...Qxf3 is routinely marked with two exclamation points.
Why the Sacrifice Was Sound
What separates 17...Qxf3 from the celebrated sacrifices that preceded it is that it forced nothing immediately. Anderssen's queen sacrifices in the Immortal and Evergreen games of 1851 and 1852 led to checkmate within a few forced moves. Morphy's did not. When the queen landed on f3 there was no mate on the board, only a judgement: that White's shattered light squares, the entombed king, and the absence of any defender near g2 were together worth more than a queen.
The mechanics rewarded that judgement. The rook lift Re6-g6 came with check, gaining the tempo that made everything work. The bishop on d7 reached h3 in one move. White's pieces, by contrast, needed three or four moves to influence the kingside, and the position never granted them one free tempo. Later analysis found that Morphy missed the fastest finish, since 22...Rg2 instead of 22...Bg2+ would have forced mate more quickly, a detail confirmed by modern engines. But the same engines confirm the sacrifice itself was fully correct, which for a positional queen sacrifice conceived at the board in 1857 remains astonishing. It is a foundation text for the study of chess tactics on weak squares.
The Aftermath: Morphy Conquers, Then Vanishes
Morphy won the match and the Congress, and the victory launched the most meteoric career chess has seen. In 1858 he crossed to Europe and defeated Adolf Anderssen, the winner of London 1851 and the strongest player in the world, by seven wins to two. Howard Staunton, the English champion whose name adorns the Staunton chess set, famously never agreed terms for a match, an episode that soured Morphy's stay in London. The formal World Chess Championship would not exist until 1886, but contemporaries had no doubt Morphy was the best player alive.
Then he stopped. By 1859 Morphy had returned to New Orleans, and within a few years he had abandoned serious chess entirely, declining all challenges. He died in 1884 having spent more years retired from the game than he ever spent playing it. Paulsen, his victim in New York, went on to a long and underrated career, contributing lasting ideas to opening theory, particularly in the Sicilian Defence. The sixth game of their 1857 match remained the brightest moment in the careers of both men, the day American chess announced itself to the world.
Legacy: The First Modern Queen Sacrifice
17...Qxf3 became the template against which later queen sacrifices were measured. When Steinitz, Lasker and the positional school codified the principles of attack, Morphy's games were their primary evidence: develop every piece, open lines toward the king, and only then strike. The Paulsen game demonstrated the furthest extension of that logic, that even the queen is expendable when the opponent's king position is sufficiently compromised and his pieces sufficiently distant. Echoes of it run through the great sacrifices of the twentieth century, from Rubinstein to Tal to Kasparov, players profiled among the famous chess players of every generation.
The game also fixed Morphy's reputation as the first truly modern player. Bobby Fischer judged him potentially the most accurate player who ever lived, and engine analysis of his games has been kind to that claim. For students today the lesson of New York 1857 is unchanged: count attackers and defenders around the king, not points of material. A queen that cannot reach the battlefield, like Paulsen's on a6, may as well not exist. It is the same discipline that governs chess endgames, applied at the moment of maximum violence.
Jaques of London — Making Chess Sets Since 1849
When Morphy and Paulsen sat down in New York in 1857, the Staunton pattern pieces created by Jaques of London in 1849 had already become the universal standard for serious play. The First American Chess Congress belonged to the first generation of great events contested in the Staunton era, on designs first turned in the Jaques workshop in London. The same pattern, from the same maker, remains the benchmark for tournament chess today.

Q: Why did Morphy sacrifice his queen with 17...Qxf3?
Morphy gave up his queen because the resulting attack on the light squares around Paulsen's king was worth more than the strongest piece on the board. After 17...Qxf3 18.gxf3, White's kingside pawn cover was wrecked, and Morphy's rook swung to g6 with check while his bishop came to h3, sealing the king in a cage of light-square weaknesses. Paulsen had no pieces able to defend g2 and f3, so the material advantage of queen against rook and bishop never mattered. The sacrifice was positional rather than a forced mating combination: Morphy judged that White's pieces, huddled on the queenside after 17.Qa6, could not return in time. Modern engines confirm the assessment, which makes the move one of the earliest examples of a sound long-term queen sacrifice.
Q: Could Paulsen have declined the queen sacrifice?
Declining was technically possible but hopeless. If Paulsen had not captured with 18.gxf3, Morphy's queen would simply have remained on f3, a monster planted next to the white king, threatening immediate destruction on g2. White's queen was stranded on a6 after 17.Qa6, far from the defence, and the bishop on c1 and rook on f1 could not cover the light squares. Analysts since Morphy's day have agreed that every reasonable alternative to accepting the queen loses material or gets mated faster. That is part of what makes 17...Qxf3 so striking: it was not a swindle that depended on a greedy capture, it was a move that left the opponent with no satisfactory reply at all. Paulsen, a careful defender, took the queen because everything else was worse.
Q: Did Morphy miss a faster win after the sacrifice?
Yes, and it is one of the famous footnotes of chess history. After 18.gxf3 Rg6+ 19.Kh1 Bh3 20.Rd1, Morphy played 20...Bg2+ 21.Kg1 Bxf3+ 22.Kf1, and here 22...Rg2 would have forced mate quickly, a line pointed out in later analysis and confirmed by modern engines. Instead Morphy chose 22...Bg2+ 23.Kg1 Bh3+ 24.Kh1 Bxf2, winning material and keeping an overwhelming attack, and Paulsen resigned by move 28. The slip changes nothing about the soundness of the original sacrifice, which was correct from the moment it was played. If anything it humanises the game: even the most gifted attacking player of the nineteenth century, in the most famous combination of his American career, settled for a clearly winning continuation rather than the absolute fastest one.
Q: Was Paulsen vs Morphy 1857 the first great queen sacrifice in chess?
It was not the first queen sacrifice, but it is widely regarded as the first great positional one played in serious competition. Earlier masters, including Greco in the seventeenth century and Anderssen in the Immortal Game of 1851, had sacrificed queens to force immediate checkmate. Morphy's 17...Qxf3 was different in kind: there was no forced mate on the board when he played it. He surrendered the queen for two minor considerations, a bishop and a shattered king position, trusting a positional judgement that took analysts years to fully verify. That conceptual leap, giving up the strongest piece for long-term domination of squares rather than an immediate finish, is why the game appears in nearly every anthology of famous chess games and why the move still features in modern teaching on attacking play.
