no.. but he did have an ace in the hole... something about R2-D2
Yeah, Luke was lucky he made it that far. He might not have made it out of the rancor pit. Lando could have been caught. Artoo might not have been in a position to help. Jabba’s people might have found the saber. It honestly is a pretty reckless plan if a hidden weapon is literally all you have. They got lucky. Or they had the writers on their side. Regardless, it still doesn’t make a lot of sense.
