Say I am a die-hard communist (I am NOT!) and I want to grudgingly admit that there's this one thing capitalists are right about. I believe I could say something like "now that's one for Adam Smith" or "...one to Adam Smith," but for the life of me I can't remember which one.
Or perhaps I'm wrong and none of those is the correct usage, in which case I'd like to know what the appropriate expression is.
