How does white win this? Can you find the winning plan without consulting the Nalimov Tablebase?

Mandil 1943

n3K3/8/B7/7p/8/8/8/k2N4 w - - 0 1

I think It looks like the most resistant line.

1.Kd7 Nb6+
2.Kc6 Na4
3.Bb5 Nb2
4.Nc3 h4
5.Kd5 h3
6.Kd4 h2
7.Bc6 Nc4
8.Kxc4

Bc4! If knight ...b6, Bb3 and the plan to me looks good.

The "most resistant line" you give, Alena, is quite beautiful as well as being somewhat humorous, with the White knight cutting off 2 squares for the Black king and 2 squares for the Black knight, as well as the Black knight cutting off the remaining square for its own king.

Yes, 4.Nc3 in the line Alena gave is a truly beautiful move in this puzzle.

Yeah, exactly right!! 1. Kd7!! - White kills two birds with one stone by limiting Black King’s mobility and trapping Black Knight. Kudos to Alena!!
