White has a huge advantage and it is time for desicive action. In accordance with his own romantic style and public demand Anderssen played

17. Nf6+

?!! The two exclamation marks are for one of the most beautiful combinations in chess history, which was started with this move. But objectively the search for beauty created unnecessary complications. The prosaic

17. Ng3 Qh6 18. Bc1 Qe6 19. Bc4 Nd5 (19... Qg6 20. Nh4 Qg4 21. Bxf7+) 20. Ng5 Qg4 21. Re4 would finish the game without any troubles, but then chess would have lost one of the jewels from it"s crown!

17... gxf6 18. exf6 Rg8!

At first sight an open g-file gives Black excellent counter-attacking chances, but Anderssen"s calculations were beyond the fears of an ordinary human being.

19. Rad1!

I"ll spare you from hundreds of analyses by following generations of chess players. After endless debate they have agreed that 19.Rad1 was better than the alternative 19.Be4. Now the best reply was 19. ..Rg4!, which would pose some difficult problems for White, but in the emerging wild complications White would, in my opinion, retain the upper hand.

19... Qxf3?

Now White" s king is suddenly just one step from decapitation. But how can we reproach Dufresne from not recognising the magic of a genius?

20. Rxe7+! Nxe7!?

Another proof that chess masterpieces require the generous cooperation of the loser! Nowadays a professional player and, of course, a computer, would have without hesitation resorted to 20...Kd8

20... Kd8 preventing the upcoming demolition, but losing anyway later after 21. Rxd7+! Kc8 (21... Kxd7 22. Bf5+ Ke8 23. Bd7+ Kd8 24. Bxc6+ with mate.) 22. Rd8+! Kxd8 (22... Rxd8 23. gxf3 or) (22... Nxd8 23. Qd7+!! - the same motif) 23. Be2+ less clear is(23. Bf5+ Qxd1+ 24. Qxd1+ Nd4 25. g3 Rg5! 26. Bh3 Bf3!) 23... Nd4 24. Bxf3 Bxf3 25. g3 Bxd1 26. Qxd1 with a boring but winning endgame.

21. Qxd7+!! Kxd7 22. Bf5+ Ke8 23. Bd7+ Kf8 24. Bxe7#

Not surprising that chess players of the time, impressed by this kind of greatness, did not want to listen to dull positional advice. But the old combinational school, led by its first knight Anderssen, was doomed in the battle against the modernized warfare techniques of Paul Morphy, whose tactics had a much better positional foundataion.
