Go up one level in this thread


I'll give you only one or two examples.
Initially there are 20 possible moves for white and assuming that the Kings pawn
makes the first move then there are 20 possible moves for black.
That equals 20*20=400 moves for a two ply search.
Continuing on with the same opening moves now there are 29 possible moves for
white once again, that equals 400 * 29 = 11,600 moves for three plys.
Then numbers grow from that point up. Set up a board and try it yourself.
His statement is that at two plys there are a total of 420 moves. He is getting
confused by adding the original 20 to the new 400 possible moves that already
include the original 20, and he carries this flawed logic throughoput his
equations. It is a simple matter of doing the math...
I hope this helps to see the errors of his ways. In all other respects his page
looks real good, and I am sure that some people will benifit from it.
