1.h7 and how can black stop white from queening?
o.k. saw it 1..f1Q 2Rf1: Rh2 and Ra2.
So maybe 1.b5…
What about –
1. a7 f1=Q
2. Rxf1 Rh2+
3. Kc1 Ra2
4. b5! (now if 4.. Rxa7 then 5. Rf6+ Kg5 6. Ra6 and White wins after 6.. Nd7 7. Rxa7)
4.. Ra1+
5. Kc2 Rxf1
6. a8=Q (and White goes winning with Q+P vs N+R)
Firt we have to find if white goes up or goes down.
Well…
1. a7 f1=Q
2. Rxf1 Rh2+
3. Kc1 Ra2
4. b5! Kg7!?
5. b6 +- however the white has to be careful

Stulzer – Just making sure. Is your central point that after 5…Ra1+ 6.Kd2 Rxf1 7.a8=Q Rf7, White’s win is there in theory but as a matter of practice still up in the air?
If I do in fact understand you correctly, I hasten to add that I don’t disagree 🙂 As White I’d have my hands full trying to bring home that ending.
There is a last wrinkle. After the try 5. .. Ra1+ you can’t play Kd2/b2 🙂

Okay, I’ll bite — why not? We’re talking about:
1.a7 f1=Q
2.Rxf1 Rh2+
3.Kc1 Ra2
4.b5 Kg7
5.b6 Ra1+
… right?
1.a7!
[1.b5? Nd6 2.a7 Ra4 3.b6 Nc4+=;]
[1.axb7? Rxb4=]
1…f1Q 2.Rxf1 Rh2+ 3.Kc1 Ra2 4.b5 Ra1+ 5.Kc2!
[5.Kb2? Rxa7 6.Rf6+ Kg5 7.Ra6 Rxa6 8.bxa6 Nc5 9.a7 Na4+ 10.Kc2 Nb6]
5…Ra2+ 6.Kb1 Rxa7 7.Rf6+ Kg5 8.Ra6 Rxa6 9.bxa6+-

In this line (4…Kg7) where the white pawn is on b6, it doesn’t matter for White King if on b2 or c2. It matters ib pawn is still on b5, see line in my post above.

Thanks, Pharaoh. That’s a nice line (1.a7 f1=Q 2.Rxf1 Rh2+ 3.Kc1 Ra2 4.b5 Ra1+ 5.Kb2 Rxa7 6.Rf6+ Kg5 7.Ra6 Rxa6 8.bxa6 Nc5 9.a7 Na4+ 10.Kc2 Nb6), and no, I didn’t see it until you pointed it out. But that’s not quite the question I was asking.
