5 line is slightly flawed, a top program will "NEVER" lose if it gets to go first. There is a significant advantage to going 1st in this game. Essentially it is a forced win for the person who goes first.
mainly since first move wins most of the games its is such a huge advantage to go first that if you are able to draw the game with the 2nd color you deserve the win. im curious how the top players in the world play when they move 2nd.
