Unless the whole point of the puzzle is to determine the logic.

Bruteforcing (aside from taking longer is just not interesting. When people are setting puzzles a lot of time and effort is put into how the logic is expected to work on the path to solving. When people post puzzles for testing if people find a spot where bifurcation is necessary they’ll generally point it out and the setter will check to see if they made an error or whether the person testing has missed some of the logic.

Guess-and-check is not brute forcing. I addressed this in another part of this thread.

Ok, what do you mean by “guess and check”?

Because general rule for a sudoku to not be considered is that at no point should you be in a position where you are needing to simply try different solution paths to find one that works.

I’d recommend watch a video by cracking the cryptic on YouTube to see how the solve works at the higher levels, as it’s possible I’m misunderstanding what you’re meaning by guess and check, and you’re meaning similar logic to what is used. In that case the problem is calling it “guess and check” leading us sudoku folk to think you’re meaning bifurcation.
