how is this so complicated?

I wasn’t talking about your “90% luck” number. I was talking about your “100% optimal” number.
your still completely missing the point. I'm saying that just because you can get lucky because of how your opponent moves... luck does not determine the outcome of a game. because your opponent is still making a choice. so you can be lucky or unlucky... thats fine. but you yourself are not a game of chess. in order for the game to be determine by luck a move would have to be made that was out of BOTH players control.
I do not disagree with you that a game, including its outcome is made up of a series of moves by two players. I do agree with you that those moves are chosen by the players and are not random. But I do not think that randomness in chess is the subject matter.
Given that in chess the consequences of a move can only be apparent several moves later, and moves that are rigorously calculated to be strong can turn out to have weaknesses that are surely practically impossible for a human to have forseen, it seems to me that Chess involves a degree of luck which is not often discussed. If you have two candidate moves, each of which seems equally strong to you, but one of which is, unbeknown to you, actually weaker, surely then it is just a question of luck which one you happen to randomly choose?
This is the original post. It is slightly different in meaning than if you take the title literally as you do. Like btickler, you have a problem listening to what other people are saying. You stick to words than meanings.
