White should win, but Horwitz gives the wrong first move. The only way to win is with a knight sacrifice that has been overlooked for more than 120 years! The star move is
1.Nd2!!
and Black loses in all variations. [The line given in BCE begins with the preparatory 1.Kf7
Kc7
when 2.Nd2
is only good enough to draw because of the weirdly stunning counter-attack 2...Kc6!!
3.Nf3
Kd5!
4.Nh4
Ke5
5.Ng6+
Kxf5
6.Nxe7+
Ke4!
