1) …Rd1 +
2)Bf1 Nb3
3)Nb3 Ra1
4)Na1 c1Q
1…Nb3 appears strong for Black.
Maybe you should change the move order since after 3)…Nb3 in your line you must consider 4.a7!
Then I propose, 1…Nb3! 2.Nxb3 forced Rd1+ 3.Bf1 Rxa1 4.Nxa1 c1=Q

1. … Nb3!!
2. Nxb3 Rd1+
3. Bf1 Rxa1
If
1. … Rd1+?
2. Bf1 Nb3
3. a7!
1. …Rd1+
2. Bf1 Nb3
3. a7 !?
1 …Nb3
2.Nxb3 Rd1+ appears to limit White’s chances with the a-pawn
@7:20:00PM,
What if 3. a7?
1…Nb3! first is a try.
Now, if 2. Nxb3 Rd1+ 3. Bf1 Rxa1 4. Nxa1 c1Q wins as pointed out Anonymous @ 7:20:00PM.
But I am not seeing a clear-cut win after
2. Ra2 Rd1+ 3. Bf1 Rxc1 4. a7 Rxf1+ 5. Kxf1 c1Q+ 6. Kg2, seems unclear.
Anonymous’ suggestion doesn’t seem to work, since White can play 3.a7! and 4.a8(Q)+. Instead, Black should transpose moves with 1…Nb3! 2.Nxb3 (2.a7 Nxa1-+) Rd1+ 3.Bf1 Rxa1 and wins.
1. … Nb3!!
2. Ra2 Nxc1
3. Rxc2 Nb3 and Black is a piece up
Certainly,
1)… Nb3
2)Ra2 Rd1
3)Bf1 Rc1
4)a7 Rxf1
5)c1=Q+ Kg2
6)Nd4
Complicated, but White have two knights to atack. I guess. (+-)
Maybe,
1)… Nb3
2)Ra2 Rd1
3)Bf1 Rc1
4)a7 Rxf1
5)c1=Q+ Kg2
6)Nd4
