What is solved?
Many things. How to make alcohol. Every possible move and combination in Checkers. Global communication networks have a solution, too...
Lots of things.
So you have to be a little more specific.
OK. With regard to chess, what does solved mean?
Lad aside and BTT:
"Solved" means every possible position has a known perfect response without ever losing due to optimal play.
But we don't know the perfect moves yet. Chess isn't solved because of that. Current engines don't know perfect moves. They calculate millions of positions and pick the "best" based on evaluation, but they can't see every possibility to the end of the game. There are simply too many variations (more than atoms in the universe). That's why top engines still lose to each other.
Chess will be "solved" when we can prove the result of perfect play from the starting position (win for white, win for black, or draw) and demonstrate the exact moves to achieve it. Until then, even the strongest engines are just incredibly good approximations, better than any human ever could be, but still not perfect.
Once perfect = chess solved.
Until that day, it's unsolved.
Checkers, Tic-Tac-Toe, etc, are much simpler games with way fewer possibilities. So for computers it was a lot easier to solve those games. Those games are deemed "solved".
Yes, so it's meaningless. There's no possible use for chess being "solved". Incidentally, obviously "what is solved?" is in relation to the comment preceding that question.

We cant exactly rule out having a perfect solution for every position and still losing by force due to opposing optimal play lol
