- Abstract:
-
The importance of the first-move advantage in rules of board and ball games is presented in this article. Consideration of the firstmove advantage i n ConnectFive lead to the invention of a new board game, ConnectSix. The valu e of the firstmove advantage can be calculated after studying the evenodd effe ct in computer gaming programs. Since the firstmove advantage can be evaluated, t he principle of nullmove pruning is identical to other pruning algorithms base d on an AlphaBeta window. This is the reason the functions of other pruning alg orithms are concealed by nullmove pruning in chess programs.
