Here's some very important advice:
If you try to use obscure rules to your advantage, your opponents can and will beat you with the nearest available blunt object. So, instead of being a cheap rule prick, be fun.
Also, if you are considering making a move which may endanger your own minifigs in order to kill the opponent, DO IT. You'll never get the chance again. Even if the loss on your side is greater than your opponent's, trust me, it's worth it.
