[The Hobbit] What was the Dwarves' Plan for Killing Smaug?

Did they even have a plan? They just show up to Erebor planning on taking some treasure and apparently never considering the problem of the giant near-indestructible dragon. What was Bilbo's involvement in their plan for killing Smaug if they had one?

They didn't really have a plan to kill Smaug.

There was a remote hope that Smaug was dead, he had not been heard from for a while, so it was possible he had died.  Short of him being dead, Bilbo was brought to steal as much treasure as possible.  It was not a well thought out plan.
