Pioneer54: was trying to imagine how your idea would work on a 12 (vertical) by 10 (horizontal) board. It would be neat if this site (or some other) offered something like an "idea editor", a system in which games could be played strictly off the record by setting up your own board size and piece array of choice, just to see what might happen by experimentation.
If you have a Windows box, you might consider getting "Zillions of Games". It allows you to create almost any abstract board game you can imagine.
