Keryo-Pente is like Pente
except that you can capture either two or
three of your opponent's stones by flanking
them with your stones. You
can capture a row that lies vertically, horizontally, or diagonally.
You win either by doing either of the following:
Place five or more of your stones in a row.
Capture 15 of your opponent's stones (as opposed to 10 in traditional Pente).
