Yes: in a drawn or won position there is at least one correct move;
in a lost position there is no correct move.
Is There Always a Correct Move?

"the best two moves are mate in 2"
++ There are no bonus points for a faster checkmate.
Mate in 1, in 2, in 3, or in 39 are all the same.

Sure there are, just ask stockfish. But yeah if we simplify like that, like I suppose we should, then moves that change the status from game theoretically you are winning to a draw or from a draw to opponent winning are worse than moves that keep the status. And the moves that change the position from you are winning to you are losing are worse than moves that change it from you are winning to draw.

I am having a problem on how do any being (including computer engines) decide on which of the checkmate pattern is better if it is already solved even though they have the same tempo... I don't know the answer...

"moves that change the status from game theoretically you are winning to a draw or from a draw to opponent winning" ++ Those are mistakes (?)
"moves that keep the status" ++ Those are correct moves
"moves that change the position from you are winning to you are losing" ++ Those are blunders (??)

And moves that the status from you can mate in 1 to you can mate in 10 are brilliant moves. They are so good that they are banned here on this site.
The answer is always yes, because if white or black always can win, then they have to play the best combination to win, and if the best combination is draw, then they have to play without errors to draw.
Only that we dont know what case is.
Just how say tyqxc.
¿Could have a game no solution determined?
I think its possible, but the possibilities trends to infinite.

Creative and unexpected moves can sometimes be strong, catching the opponent off guard. These moves might not conform to standard principles but can still be effective.

This is obviously not true.
The above position is a draw.
If you are white, you can play any move you wish, and you can't lose. You can try your best to win, but it's not about you to find the best move (there is no best move). The only hope is that the opponent fails to hold the (obvious) draw.
If you are black, still every move draws. Maybe you'll have to be a bit careful later, but still, it's an easy and obvious draw. Again, there is no best move.

I understand that chess is still not mathematically solved yet, but am curious if in theory there is always a singles best/correct move?
Sometimes it is obvious such a move exists (e.g., a checkmating move), but other times it's not so clear what the absolute best move might be in any given situation. Nevertheless, I wonder if there IS still a correct move (even if we don't know it )?
Hopefully my question makes sense.
(p.s., I wonder if there can also be more than one correct move? )
... if in theory there is always a singles best/correct move?
No, of course not. There can't be a single best move here, for example. (And if you're in a theoretically losing position you only have theoretically best moves.)
Well sometimes moves can be equal aka both of the best two moves are mate in 2 or no matter which move you make opponent has mate in 1. But outside of moves being equal, then other moves are better than others, of course.
Yeah, maybe the question didn’t make sense, since the answer sounds so obvious, that I’m not sure I answered the right question.
