I've posted my favorite on the pente discussion board as well as a puzzle problem which illustrates how different it is from current pente while still having only a slight change in the rules- Gary and other top players, I'd love to see this game explored at your level of play; it seems to me to be almost pente+ when I have played it(a deeper and richer game) but I haven't had the chance to explore its depths with players of your calibre.
