{{block indent|1='''1. e4 c5 2. d4 cxd4 3. Nf3 Nc6 4. Nxd4 e6 5. Nb5 d6''' It is hard to believe that this modern ''[[Glossary_of_chess#tabia|tabiya]]'' occurred a century and a half ago! '''6. Bf4''' Fischer's favourite, but later everyone began preferring Karpov's favourite move 6.c4. '''6... e5 7. Be3 f5?''' More than a hundred years were required, in order to show that after 7...Nf6 8.Bg5 Be6 Black has nothing to worry about, for example: 9.N1c3 a6 10.Bxf6 gxf6 11.Na3 d5! etc. (Fischer–Petrosian, Buenos Aires 1st match-game 1971). However, Anderssen with his aggressive style wanted to hasten a crisis in the centre: previously such methods had always worked for him. '''8. N1c3!''' Morphy sensed that chess logic was on his side, and he found an immediate refutation of Black's premature activity. '''8... f4''' If 8...a6, then 9.Nd5! axb5 10.Bb6 Qh4 11.Nc7+ Kd7 12.Nxa8 Qxe4+ 13.Qe2 is decisive. '''9. Nd5! fxe3 10. Nbc7+ Kf7 11. Qf3+''' 11.Nxa8 was probably stronger, but Morphy did not want to divert his sights from the enemy king. '''11... Nf6 12. Bc4 Nd4! 13. Nxf6+ d5! 14. Bxd5+ Kg6?''' White would have been caused more problems by Zukertort's suggestion of 14...Ke7. '''15. Qh5+ Kxf6 16. fxe3! Nxc2+''' This loses immediately, but 16...Qxc7 would merely have prolonged the agony: 17.Rf1+ (much clearer than Maróczy's suggestion of 17.exd4 Ke7 18.0-0-0) 17...Nf5 18.Rxf5+! Bxf5 19.Qxf5+ Ke7 20.Qe6+ Kd8 21.0-0-0! Bd6 22.Bxb7 etc. '''17. Ke2 {{chessAN|1–0}}''' Black resigned in view of the continuation 17...Nxa1 18.Rf1+ Ke7 19.Qxe5+ Kd7 20.Be6+ Kc6 21.Rc1+ Kb6 22.Qb5 mate.}}
