Is there a 'theory' / method to calculating positions like this?

I don’t see any position. Please make sure it’s an inserted board, not a screenshot. The mobile app can’t see screenshots.
Oh! I am such an idiot ;) Forgot to share the actual position. Here it is. [Event "marcelosem vs. DrFleonSunoco"] [Site "Chess.com"] [Date "2025-09-30"] [White "marcelosem"] [Black "DrFleonSunoco"] [Result "1/2-1/2"] [WhiteElo "1751"] [BlackElo "1729"] [TimeControl "600"] [Termination "Game drawn by agreement"] 1. e4 c6 2. Nc3 d5 3. exd5 cxd5 4. d4 Nc6 5. h3 Bf5 6. Nf3 e6 7. a3 Nf6 8. Bg5 h6 9. Bh4 Be7 10. Bd3 Bxd3 11. Qxd3 O-O 12. Ne5 Nxe5 13. dxe5 Nd7 14. Bxe7 Qxe7 15. Qd4 Qc5 16. Qxc5 Nxc5 17. O-O a6 18.

Kd4 Kc6 33. a4 b5 34. axb5+ axb5 35. g4 g6 36. h4 h5 (36... Kd7) 37. g5 Kb6 38. Ke4 Kc6 39. Kd4 1/2-1/2
Move 36 (I played the losing h4)
After move 25, this position seems terribly drawish, There's equal material and no pawn majorities that would allow either side to create a passed pawn, I think you and your opponent both played the rest of the game quite well, although there wasn't much to do.
I don't understand why you called 36.h4 "losing." I can't see anything wrong with it. And your suggested 36...Kd7 seems to just lose to 37.Kc5!
Is there a 'theory' / method to calculating positions like this. The game ended in a draw, despite me playing a losing move here (my opponent didn't find a winning continuation, which is not trivial). The computer says there's only one non-losing move.
My question is: is such position trivial to calculate, given some proper method/system (if so, what IS this method?). Or is it just a tough calculation grind, evaluating every possible continuation?
Thank you
