A. Munoz, you just need to calculate a little further. White pawn queens first in all (reasonable) variations. Black knight is too far from the action and will either not survive (at which point White will win by virtue of having another advanced passed pawn and of having White king available to capture Black’s b-pawn) or will move closer to the action and allow White to capture the black e-pawn.
I looked this game up to see how Alburt won. When I saw that Lerner didn’t resign for another sixteen moves, I didn’t feel so bad about not finding this position completely clearcut.
Nxc5 and b5 to get two passed pawns. The knight can only stop one of them.

That’s 2.b4, right?
Why can’t Black give up his knight for one of the pawns, play …Kf2, and promote his e-pawn?
maybe
g4 cxg4
na5 wins
Artic Knight
”maybe
g4 cxg4
na5 wins”
You mean,
1b4 cxb4
2.Nxa5 but then
2…Kd4 and Black looks fine.
I just cant figure it out. Nxc5 looks good but a gamble.

Here is one possible line:
1.Sc5: bc5:
2. b4 ab4:
3. a5 e4
4. a6 Kf2
5. a7 e3
6. a8Q e2
7.Qa1 e1Q
8.Qf6:+ Kg2 (..Kg3 9. Qc3+ +-)
9.Qg5+ Kf3
10.Qd2
i think this is winning.
if 2. .. cb4: there is
7. Qf5+ and Kd2 stopping the black e-pawn.
Tobe
1.Sc5: bc5:
2. b4 ab4:
3. a5 e4
4. a6 Kf2
5. a7 e3
6. a8Q e2
7.Qa1 e1Q
8.Qf6:+ Kg2 (..Kg3 9. Qc3+ +-)
Typo in the parentheses? White does seem to win, but not with 9.Qc3+? bxc3.
early 1.b4 is playable?
‘early 1.b4 is playable?’
1.b4 cxb4
[1…axb4 2.Nxc5 Kd4 Black is ok]
2.Nxa5 Kd4 and Black is ok
Here is how the game went on, (see move 65.Nxc5) :
