valid chess positions is in the neighborhood of 10^40^ to 10^44^

Lol, big board you're playing with....

A position is the arrangement of all the pieces on the board.

If you don’t limit it to valid positions/arrangements it’s like 10^120. Closer to the “number of X in the observable universe” caliber of number.

So I think I was wrong, but you are too lmao.

10^120^ is the number of valid game-trees, or valid ~80 move games.

The much smaller number I quoted above, though, IS the valid positions, I was thinking it was actually the trimmed down "truly valid" game-tree sequences.

Isn't math fun? Limitless ways for us to be wrong!
