First move is 20 for one side and 400 for both. Idk, a very large number!
How many chess positions are possible after the first 2 moves?

Harder than it sounds. Chess mathematicians, take it away! The first move for each side is easy...then it gets more complicated with lines like 1 b4 e6 2 b5 Ba3 and so forth. Black's move Ba3 was influenced by White's b5.
