[Event "1<sup>st</sup> American Chess Congress"]
[Site "New York, NY USA"]
[Date "1857.11.03"]
[Round "4.6"]

16.Ra2 Rae8 17.Qa6

{[pgndiagram] Morphy took twelve minutes over his next move, probably to assure
himself that the combination was sound and that he had a forced win in every
variation.}

17...Qxf3 !! 18.gxf3 Rg6+ 19.Kh1 Bh3 20.Rd1 ({Not} 20.Rg1 Rxg1+ 21.Kxg1 Re1+ -+)
20...Bg2+ 21.Kg1 Bxf3+ 22.Kf1 Bg2+

(22...Rg2 ! {would have won more quickly. For instance:} 23.Qd3 Rxf2+
24.Kg1 Rg2+ 25.Kh1 Rg1#)

23.Kg1 Bh3+ 24.Kh1 Bxf2 25.Qf1 {Absolutely forced.} 25...Bxf1 26.Rxf1 Re2
