Yes but you do not need to analyze everyone of them and no program does it. >Then there are 400 * 20 = 8,000 for white. The number of possible games of 3 plies is more than 8000. The number of possible positions that you get after 3 plies is smaller because 1.e4 e6 2.d4 is identical to 1.d4 e6 2.e4 Then there are 8,000 * 20 = 160,000 >for black, and so on.

No The number of possible games is higher than 10^120 The number of total positions is clearly smaller. Maybe 10^40 and it is easy to prove it. It does not mean that it is possible to solve chess in our life time but it also does not mean that it is impossible. Uri
