You are correct, chess does indeed have a solution. If it didn't, then there must exist some position where multiple results could happen with optimal play from both sides, which is clearly a contradiction.

There is no need for anecdotal evidence when the proof I have provided is simple and rigorous (I have sacrificed some rigorousness for simplicity, but one could certainly come up with a more rigorous proof if one wished). Furthermore, I don't see how this is even evidence in support of your statement.
> Essentially White has to make a mistake for Black to win. White always does what Black is doing with half a tempo in advance.
Okay, so you are saying that chess engines and humans are imperfect. This is true. I don't see what this has to do with chess having a solution.
> I am creating a fun game of mine with solutions
What game is that? You only mentioned it once and then never said what it was.
> since Chess is clearly a solved game.
If you define "solved" as "has a solution," then yes, chess is "solved." But this is not what most people mean when they say "solved." If there is an empty crossword puzzle, most people would not consider it solved even if it does have a solution. Similarly, even though every chess position has optimal solutions, we do not know those solutions so chess is not solved by any reasonable definition.
Furthermore, you even support the fact that chess is not solved by saying that chess engines are fallible, since, you say, they can win with Black and White must make a mistake for Black to win (I am assuming an engine vs. engine match). This in itself does not prove that engines are fallible, because even though you say that White must make a mistake for Black to win, we do not know this with certainty, because chess is not solved. If, however, you created a position in which you had an engine play itself (say Stockfish), and got more than one result for different games, then this is proof that engines are fallible. Nevertheless, despite your lack of proof, your statement is still in support of the fact that chess is not solved, and then you directly contradict it by saying chess is "clearly" solved. Clearly there is some cognitive dissonance that you should probably address.
