Stated plan
Deliver Ne2+ to force the king into a mating net, followed by pawn promotion to deliver checkmate.
Resolves to c3e2 · −0cp
Reasoning
Black's knight can deliver a devastating check: 1...Ne2+ forces the white king to h1 or h2, since nothing can block or capture the knight. Then the g2 pawn promotes with check (g1=Q+), and because the knight covers all escape squares (g3, f4, etc.) and the queen covers the remaining squares, this is checkmate.
