I just had someone swipe an elimination out from under me that they would never have been capable of without my armies having eliminated all the other countries... and I don't mean that I wasn't able to finish, we're talking about a freestyle game and I was still playing, so in the middle of my turn he/she began their turn and took the last country of an opponent, taking the elimination and the cards

It felt like a dirty move to me, assuming that they did it on purpose, but I'm wondering if I'm alone in this? The question is... do you consider this a dirty move by someone taking
advantage of the freestyle mode when there are only 2 players left in the game, or is this just excellent
strategy in a freestyle game?
Just FYI, I don't mean this post to be bitter in anyway. Yes, it did piss me off at the time, but in the end when I asked him about it, he did point out that he realized I was about to win the game... so, could I really blame a player for a last-ditch effort? Nah...
