If the Cubs can get to Billingsley early, you definitely have a chance. Even though Billingsley's ERA is sub 3.2, he gives up quite a few hits each outing. If the Cubs can get the hits and capitalize on them, I think Z shuts down the Dodgers offense.
However, I picked the Dodgers to win the NL the other day and I'm sticking with that prediction. If the Cubs win tonight, I think Harden throws a good 5 or 6 innings in Game 3 and assuming the 'pen can hold it for you guys, you'll be in the driver's seat to win the series.
