Paul Morphy vs Adolf Anderssen

Paris, late 1858. Between their formal match games, Morphy and Anderssen also played a number of off-the-record skittles. This celebrated casual sparkler—later nicknamed “Keep Your Eye on the Paul”—belongs to that Parisian flurry, with both men happy to dive into the Romantic era’s favorite powder keg: the King’s Gambit Accepted. The broader backdrop: Morphy had just established clear supremacy in their official encounter, winning the match +7 −2 =2—a result that effectively crowned him the world’s leading player.

The Players

Paul Morphy (1837–1884) was the game’s first universal star—blistering development, clean calculation, and a ruthless instinct for initiative. Adolf Anderssen (1818–1879), the hero of London 1851 and author of the “Immortal” and “Evergreen,” embodied Romantic swashbuckling. Their 1858 clash symbolized the handover from brilliant chaos to brilliant clarity. (Match overview.) ([SJAKKNYHETER.NO | Nyheter om sjakk][2])

The Game

Morphy chooses 1.e4 and offers the King’s Gambit. After 3…g5 4.h4 g4 5.Ne5 Nf6 6.Nxg4 Nxe4 7.d3!, White meets Black’s …Nxe4 resourcefully and then targets the f-file and dark squares. The sequence 8.Bxf4 Nxh1 9.Qe2+ is pure Morphy: allow Black’s knight adventure to h1 only to hit back with tempo and king exposure.

The key central skirmish arrives with 10.Nf6+! drawing the black king to c7 after 11.Bxc7+ Kxc7 and then 12.Nd5+ Kd8 13.Nxe7. Material remains roughly balanced, but Black’s king is air-exposed and his pieces are uncoordinated. Morphy’s 15.Qf4 calmly re-groups, and 16.Qxf7 snaps a pawn while keeping development lead.

After …Bxh4+ 17.Kd2 …Re8 18.Na3 …Na6, 19.Qh5! and 20.Qxh1 leave White with a stable material plus and the initiative. With 21.Qh4+ and 22.Rb1!, Morphy adds a brutal rook swing to b1—a thematic King’s Gambit motif: b-file pressure plus checks on the dark squares. When Anderssen grabs on a3, 23.Qa4+! lands, and Black resigns: the king is stuck in a mating net with Rb3–b7+ or Qxa3 ideas looming; material losses are inevitable with the monarch walking the plank on d7/c7.

Turning Points

• 9.Qe2+: Punishes the knight’s foray to h1 by yoking it to a series of checks; Black cannot consolidate without misplacing his king. (PGN/365Chess.) ([365chess.com][1])
• 10.Nf6+! 11.Bxc7+: Forcing the king to c7—a long-term liability in an open board. ([365chess.com][1])
• 16.Qxf7: Morphy pockets a pawn and keeps momentum; Black’s …Bxh4+ proves a tempo but not a cure. ([365chess.com][1])
• 22.Rb1! followed by 23.Qa4+!: The clincher. The b-file rook lift and the queen check combine to trap the king and overwork Black’s pieces; databases note resignation here with no satisfactory defense. (PGN collections.) ([Scribd][3])

Aftermath and Legacy

Though “only” a casual, the game is a tiny King’s Gambit clinic: rapid development, pressure on f and b files, and merciless exploitation of an exposed king. Modern databases catalog it under ECO C39 (Kieseritsky, Berlin Defense), and it remains a staple in King’s Gambit anthologies for the instructive rook lift to b1 and the final Qa4+ switch.
