Using minmax algorithm to play N in a row game with a human player and then compare the performance when we use AlpahBeta pruning and we don't use it. The Performance measurement here is based on the number of board evaluations not on milliseconds (which is so wrong Because then it's not machine independent).
The heuristic I implemented was very simple. It depended on the idea of how max number of player's chars in a row (Horizontally, vertically or diagonally). Finally Tell me if you could beat the AI :)
