Ok, here's the whole line :
[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "e8=N!!"]
[Black "?"]
[Result "*"]
[SetUp "1"]
[FEN "8/p3P3/rp6/kp6/1p4PK/1P6/1P5p/4r2R w - - 0 1"]
[PlyCount "31"]
1. e8=N Rg1 2. Kh5 Rd1 3. g5 Rg1 4. Kh6 Rd1 5. g6 Rg1 6. Kh7 Rf1 7. g7 Rg1 8.
Kh8 Rc1 9. g8=Q Rg1 10. Qg7 Re1 11. Kh7 Rg1 12. Qg6 Re1 13. Kh6 Rg1 14. Qg5 Rf1
15. Kh5 Rg1 16. Qg3 *
Now, white king will go shelter on g2 and white have 2 mate threat N->d6->b7
mate and R->a1 mate
