Two players play a game on an infinite board that consists of unit squares. Player I chooses a square and marks it with O. Then player II chooses another square and marks it with X. They play until one of the players marks a whole row or a whole column of five consecutive squares, and this player wins the game. If no player can achieve this, the result of the game is a tie. Show that player II can prevent player I from winning. combinatoricsgamegame strategywinning strategy
