Forum:Luke's intent for his message to Jabba?

OK - was watching ROTJ today and I was wondering... was there an intention of Lucas (or whoever wrote ROTJ) behind what we see in the movie?

Obviously Jabba would say no to his request to give back Han, so was there an undertone to this?

Did Luke use his message as a method as a decoy to possibly lower Jabba's guard - in that he let Jabba think that this is the "best" that Han's friends can do? Then use this decoy to, as previously mentioned, get Jabba to lower his guard and come in with the real plan - with Leia in disguise - to free Han?

What do you think?
