Yikes, that is an amazing one!

1.Nf5!
   [1.Nd5 Ka4 =]
1...Ka4
   [1...Re4 2.Nd4 Ka4 3.Ra1+ transposes to the main line;
    1...Re5 2.Nd4 Ka6 3.Nc2! Rxe7
       (3...Ka5 4.Re1 +-;
        3...Re2 4.Re1 +-)
    4.Nb4+ Kb5 5.Nd5+ +-
   ]
2.Nd4
   [or 2.Ra1+ Kb4 3.Nd4 Re4 4.Rc1, which transposes to the main line
   ]
2...Re4 3.Ra1+ Kb4 4.Rc1! Ka3 5.Rc3+ Kb4 6.Re3! Rxd4 7.Re1 +-
