@CaseyReese -
no.
i never said from starting position, or game tree.

actually mere possible single move notations.
my example clearly unmisunderstandlingly showed this. (and excluded your answer)

You asked about possible moves. Each possible move creates a new position. Shannon calculated the number of possible positions. See the second paragraph under "Shannon's Calculation."

"In the game of time there is only two moves that matter: the one that starts the game and the one that ends it"

According to this StackExchange post, it's either 15116 moves for algebraic notation or 1968 moves for UCI notation. Even if that's not the answer you are looking for, there is enough math there for you to fix it and give us the answer that you think is correct. https://chess.stackexchange.com/questions/33329/how-many-possible-chess-moves-are-there

@CaseyReese

you are still wrong.

i asked about merely the moves, isolated from any game or position and i gave the example and a rough incomplete attempt to calculate it.

please refrain from any further comment unless you start understanding the issue!
