Chess CAN never be "solved". There is no "best move".
You can never predict what kind of move will tick, inspire, amuse, or bore your opponent. Since you don't know how your opponents deep game psychology might work. You don't know what his game strategies are, what kind of blundering tactics he might fall pray to. The "best move" to them is not the same "best move" to the next opponent.
Or, say even that a player did know exactly what would provoke one of these emotions from his opponent. Consider that the player played a "tricky" move. Even if it wasn't considered optimal by FIDE rating standards. For instance, player may intentionally sacrificed his Queen to gain better checkmate position. FIDE analysis would have regarded it a "dumb" move. Despite this, the player knew that he could use it to trick his opponent into thinking about making a tempting follow-up. The opponent didn't know the move he was baited into was going to be a blunder.
In both situations of knowing and not knowing your opponent's psychology which influence his moves, the "right" sequence of moves that would lead to the "best game" is completely fruitless and inobtainable.
Entièrement d'accord avec toi !
C'est d'ailleurs aussi pour cela que l'ordinateur décrète les supers coups et les coups brillants car ces derniers ne rentrent pas forcément dans la logique classique du jeu à un moment précis du jeu. Ces coups sont d'ailleurs souvent des sacrifices de pièces ou des coups qui vont à l'encontre d'un jeu dit "classique". Ces coups sont d'ailleurs considérés comme des erreurs si la suite n'apporte pas de gain de pièce ou de gain de position.

"over 90% of those games are agreed drawn in positions where neither side knows what the theoretical result is."
++ No.
93% of ICCF WC games end in draws
Of the draws, 74% are agreed, 16% are 3-fold repetition, and 11% are table base draw claims.
Most of the agreed draws are in positions where both sides know that the theoretical result is a draw and where both sides are confident that their opponent will not make any mistake.
They do not agree on a draw in the initial position, though they both know that the theoretical result is a draw, because in 7% of games one player will make a mistake and lose.
There are a few exceptions, where players agree on a draw for convenience because of tournament standings, like coasting to victory with draws after a couple of wins or ending a bad tournament with draws after a couple of losses.
Here is the most recent finished ICCF WC game. It is 99% sure to be a perfect game with no errors. It ends in a draw because of a forced simplification to a 7-men table base drawn rook ending.
