Iago

Iago is an abstract strategy game for two players. It is based on Othello, but starts with an empty board and has rules for forced capture, like checkers. Enemy disks that are flipped over by being sandwiched by your disks become the third color, red, instead of your color. If the red disk wants to flip over again, one of your disks sandwiching it must be in the outer area or in the center space. Your final score is determined by multiplying the number of discs in the inner area by ones in the outer area. Like Iago, who tricked Othello in Shakespeare's tragedy, you can use these rules to cunningly outsmart your opponent. —description from the designer
