My feeling is that Andy is facing an opponent he has played before and who he has a good H2H, will be back on stadium 1 which plays differently to the other court, and this will help him. Remember the US Open and how he played on the main court to his matches on the second court.
In general court conditions are not great for Andy in Indian Wells. There is a myth that Andy is best on slow courts, which is not always the case. US Open slow court is perfect for Andy, espescially Ashe, which is noticeabally slower than the outsider courts. Here, I'm not sure what it is, something about the courts that Andy does not like.
