More typical Terry NONSENSE!

 So please don't be such a mule.

Hee Hawww
You are disconnected from Reality!

In this tree, there are 20 possible moves for white. There are 20 * 20 = 400
possible moves for black, depending on what white does. Then there are 400 * 20
= 8,000 for white. Then there are 8,000 * 20 = 160,000 for black, and so on. If
you were to fully develop the entire tree for all possible chess moves, the
total number of board positions is about 1,000,000,000,000,000,000,000,000,
000,000,000,000,000,000,000,000,000,000,000,000,000,000,
000,000,000,000,000,000,000,000,000,000,000,000,000,000,
000,000,000,000, or 10120, give or take a few.
That's a very big number.
For example, there have only been 1026 nanoseconds since the Big Bang.
There are thought to be only 1075 atoms in the entire universe.
When you consider that the Milky Way galaxy contains billions of suns, and there
are billions of galaxies, you can see that that's a whole lot of atoms. That
number is dwarfed by the number of possible chess moves.
Chess is a pretty intricate game!
No computer is ever going to calculate the entire tree.

 What a chess computer tries to do is generate the board-position tree five or
10 or 20 moves into the future. Assuming that there are about 20 possible moves
for any board position, a five-level tree contains 3,200,000 board positions. A
10-level tree contains about 10,000,000,000,000 (10 trillion) positions.
