Okay, I obviously need to keep Jim from getting one of my major pieces for free, so: Bishop to d6.

This is a purely defensive move that gives me no advantage what-so-ever. It does not put me into the offensive. It does not give me any future develomental choices. It does, in fact, leave me vulnerable to further offensive moves by Jim. And Jim is being very offensive at the moment.
Okay, I am sorry, I couldn't help myself. I will behave from here on out. Oh, and I've got that title for the bridge I have been meaning to sell.

Well, such is the nature of chess, what can I say?
Bishop g-5 to h-6...
