I see nothing. I could drag it out an extra turn by dropping an SC instead, but that wouldn't be pretty useless...
Don't feel badly about talking me into that sacrificial move, because I honestly needed very little convincing to make it. I wanted to move the game along and that's the best way I saw. I probably could have avoided this situation a few turns back, but I think the outcome would have been very similar in the end. It was a good game though, and I enjoyed it. It's just too bad it was so short (not that you consider that a bad thing :)).
