- One could change the rules so the last to make a move loses (like in
- some versions of NIM). I can't off-hand think of an easy winning
- strategy in this case. However, it may be that (like in NIM) you can
- make a small variant in the endgame of a strategy that works in the
- last-move-wins case.
