Possible positions after 40 moves

The number of possible chess games lies between 10^29241 and 10^34082.

The number of legal chess positions is 4.82 * 10^44

However, as the 3 diagrams show, the vast majority of those positions contain 3 or more rooks and/or bishops per side, which makes no sense.
A better estimate is thus 3 * 10^37 positions

Of these 10^17 positions are relevant.

Yet despite these numbers being so large, my IQ is larger.😎🤓

After 40 chess moves, assuming there were no peices taken, there can be 10^120 possible positions. However after 40 moves peices are likely taken with some peices stuck, so there is more realistically around 10^100 moves. Possible chess moves are statistics, like typing out 1TB in a .txt file in a laptop with 40GB.
