Hmm. This means that if you only have one movable piece, you lose. That moves the bar significantly. On the other hand, it might force you to move pieces that you *can*, but don't *want* to move, which I think is good for this game.
Funnily enough, we didn't think of that at all. We only tried it for a few games, and the "can, but don't want" situation occured, which meant that the game didn't get to a point where there was only one moveable piece (someone would end up with their pieces immobilized, and/or sunk as a result of a forced move). We'll give it a few more games, and see how often/when that occurs. Perhaps the rule could be further modified so that 'one piece' means it can always be moved. We enjoy the mechanics and strategy of the game a great deal; so it's a 'problem' we'll probably work on 'solving' a bit more-- though we both enjoy playing games, we're new to the theory/playtesting end of things, so what seems like a good idea could be a big old misstep. I'll keep you (and the list) posted. Todd -- http://www.cntr-band.com/index.htm
