If AC can string together two wins in the US Open Cup, it looks like Chicago will be playing here in the third round. Many different places I've checked have the Fire down as the #5 MLS team in the tournament (exactly the team AC would play after two wins).
Who is playing AC? Des Moines Menace (PDL) in the first round, then NSC Minnesota Stars (USSF2) or the Kansas City Athletics (USASA). http://thecup.us/2010-lamar-hunt-u-s-open-cup-bracket/
