On a serious note, my fiercest fights are usually against Germans/Austrians, they spend a whole lot of money in this.

I've only lost one +10 tokens auction and that was against a Greek. 25 tokens down the drain. Since then I've been more cautious.

Also I don't like this system. I believe in first come - first served. I rarely interfere with an auction that already has bidders. A matter of courtesy.
