I love getting the "Piledriver" achievement as much as possible, since it's such a great way to catch opponents off guard who themselves might have gone for the automatic double Province. At the end of this City-Lab-Uni-GM-Trade Route game I have exactly $16 and 8 Buys due to a Chancellor I managed to pick up with Uni and draw immediately. At this point, Cities + Labs were obviously gone.
