The two players move alternately by connecting two dots by a horizontal or a vertical line. The player who has the most number of squares wins. Note that a player is not forced to complete a square and this leads to the first strategy. Consider this boring game on a 6x7 grid. The players have only used horizontal lines.

Clearly, this strategy can be defeated by having many short chains but that is when the game gets really interesting. Three problems for this week. Group entries are allowed but only one coffee cup will be awarded each week. Unless otherwise specified, the submitted answer should include the reasoning behind the solution. For those who really want to challenge themselves try to find the winning moves in the next two games.
