Opposition-like with pawns instead

Is there a name or technique to easily know to push two or one space for the pawn. Similar to the rules of opposition of keeping a certain distance away or something. Apart from manually reading.

I haven't seen anything like that. I understand you have to consider all combinations to come up with the best one.

In case i wasn't clear. 1 space push is winning 2 space is draw.

The pawn you are looking to push is essentially a reserve tempo. When you have nothing to improve the position, you make a move with the pawn, placing Black in Zugzwang. If you do it twice, you win. If you get zugzwang only once, you draw. So if it is White to move, paying h3 forces Kh8. 1. h3 Kh8 2. h4! Kg8 3. h5 and now you have the King on the square he started on but you can swap Rook pawns, stopping the draw. 3...Kh8 4. g6 hxg6 5. hxg6 Kg8 6. g7 and Black cannot go to h8. 6...Kf7 Kh7 and Black promotes to a Queen next move.

Let's say White blunders and plays 1. h4?? Kh8 2. h5 Kg8 3. g6 and Black should be able to draw here.

I'm not aware of any rules of thumb that would help to solve this position. It's just a matter of concrete calculation. You should calculate both variations 1. h4 and 1. h3 and see if one of them wins. That should not be too difficult since black must protect h7 and so can only move his king between g8 and h8.

Absolutely.

It looks pretty that the white pawn steps in "distant opposition" to the black h7 pawn with h3. But that's just an illusion. Change the position somewhat, putting the black king to h8, and now h4 is winning and h3 is a draw, instead of the other way. Calculation is required, there's no way to avoid that with a rule of thumb.

Yeah - I don't know of any rule here. This is just straightforward calculation.

But it's not terribly difficult - you know that Black's moves are going to be the king shuffling back and forth between g8 and h8. So then it's just advancing the pawns in your mind and counting squares (or counting half-moves), until you reach this point:

If it's White to move, it's a win (pawn to g7 and Black is forced to vacate the corner).

If it's Black to move, it's a draw (Kh8 and Black's king can't be forced away without stalemating).

Great explanation! Thank you!
