Rf1+ After Ke2/d2/c2 Rxa1.
1.Rf1+ followed by 2.Rxa1 with a rook advantage… 🙂

1. Rf1 ..Kd2
2. Rd8 ..Kc3
3. Ra8 ..Rh6
4. Kg7 wins
I wonder if:
1 Rf1+ Kc2
2 Rxa1 Rb1
3 Ra2 Rb2
4 Rc8+ Kb1 (4 .. Kb3 5 Ra1)
5 Ra1+ Kxa1
6 Rc1+ Rb1
7 Rh1! Rxh1
8 a7 Rc1
9 a8=Q+ Kb1/Kb2
10 Qb8+ and
11 Qxh2
might do the trick?
If 7 a7? then 7 .. h1=Q+! 8 Rxh1 Rxh1+ and the king is not safe anywhere. It can be chased to .. Rb1+, Ka6 but then .. Rb2, a8=Q Ra2+, Kb7 Rxa8 leads to a draw.
I hope is not as complicated as i’m thinking…
1.Rf1 Kc2
2.Ra1 Rb1 (2…Rh6, 3.Kg7 h1=Q, 4.Rh1 Rh1, 5.a7 +-)
3.Ra2 Rb2
4.Rc8 Kb1
5.Ra1 Ka1
6.Rc1 Rb1
7.a7 h1=Q
8.Rh1 Rh1
9.Kg7 Rg1,… till rb1, Ka6 +-
This looks right
Rf1+ Kc/d/e2
Ra1 Rh6+
Kg7 h1(Q)
Rh1 Rh1
a7 Rg1+
Kh6-g5-h4-g3-h2 and Black runs out of checks.
White wins with Rb-e8+
(depending on where blacks king has moved) and a8(Q).
1.Rf1 Kc2
2.Ra1 Rb1 (2…Rh6, 3.Kg7 h1=Q, 4.Rh1 Rh1, 5.a7 +-)
3.Ra2 Rb2
4.Rc8 Kb1
5.Ra1 Ka1
6.Rc1 Rb1
7.Rh1!!!!!!and white wins
