Yeah, you think you're smarter than they are. Believe me, they're professionals. They do this for a living. They know how to screw you without getting screwed themselves.
When you opened the account at Chase, you put your neck on the line. When that check turns out to be fraudulent, they're not going to go looking for the people who sent it to you -- They're going to come looking for you, because you cashed it. And, when you filled out the information on the little card to open the account, you told them right where to go to find you.
Unless you opened the account under a false name and social security number, in which case you just doubled the charges against you.
Y'know that house you and your wife-to-be were planning on buying? Forget it. Your credit is going to be screwed for 7 - 10 years. And, even then, you'll have to explain to potential creditors why you got busted for knowingly cashing a bad check.
Oh, and I hope your new wife doesn't mind spending her wedding night making a conjugal visit.
You are so screwed.
I really hope that you didn't open that account...
