, or roughly 1043″. This includes some illegal positions (e.g., pawns on the first rank, both kings in check) and excludes legal positions following captures and promotions. After each player has moved a piece 5 times each (10 ply) there are 69,352,859,712,417 possible games that could have been played.
How many unique positions are there in chess?
There are 400 different possible positions after one move each. There are 72,084 different possible positions after two moves each. There are over 9 million different possible positions after three moves each.
Do you win chess if you get your King to the other side?
When a King reaches the other side of the board ( i.e. “the 8th rank” — the farthest opposing row of the board), nothing happens. A King will remain a King. Whether the King moves to a square in the 8th rank to get out of check, or capture, or make a regular move, it remains the same piece with the same abilities.

How many legal positions are there on a square board?
Since each location on the board can be either empty, black, or white, there are a total of 3 n2 possible board positions on a square board with length n; however not all of them are legal. Tromp and Farnebäck derived a recursive formula for legal positions
How to calculate the number of possible games?
The total number of possible games can be estimated from the board size in a number of ways, some more rigorous than others. The simplest, a permutation of the board size, (N) L, fails to include illegal captures and positions. Taking N as the board size (19×19=361) and L as the longest game, N L forms an upper limit.
