Business Genre
Short Business Description
When contemplating what box to give away, count out the number of boxes a chain reaction would be worth. Is there another run that could give away that has fewer points?
Long Business Description
Let your opponent win the last two boxes in any chain longer than three squares. This may seem sacrilegious, as you're giving away free boxes, but what it actually does is force the other player to take the two boxes and then give you the next available chain. Note that this strategy only works if there are no open moves left -- otherwise they could take the two boxes and still avoid giving you a chain. When played well, this strategy will win you most games.
In serious games, this is called a "double-cross." Double-crosses are the heart of serious dots strategy.
Once you make a double-cross, you gain control of the board. Your opponents only moves are to open up a new chain for you or take the two boxes you've given them
