Do the best players have more draws in checkers? I read some years ago that chinook had a lot of draws because of the style of the machine and that the result was 2:1 and 67 draws if my memory is correct. I suspect that one of the reason that chinook could win humans in checkers is the fact that this game is less popular than chess so humans know it less. The game of checkers is also more simple than chess(the number of the legal positions is clearly smaller because the pieces can be only in 50 squares when in chess there are 64 squares and there are only 2 kind of pieces for every player). The fact that the game is more simple help the machine to get better result and I wonder if modified chinook can win 12*12 checkers against the best humans when every side begins with 30 pieces(in this case I believe that the game is not more simple than chess).
