(And that's >probably a really bad sentence.) Yes, this is possible. I was thinking that this would be a bigger hack than just using DTC, but I suppose it's a hack, no matter what you do. :) It's sort of like this thing in Japanese Go where there's a certain corner stone configuration that they score it as even, but if you play out the actual move sequence, one player would get more stones than the other. It's somewhat illogical, but the rule was made, and that's the way it is. Dave
